New Grower berry ryder and sour diesel

[sativalover]

the third day rest
nothing at all unless for some reason there is a problem
but in this day of "rest"
more rest for the farmer because the plant and microbes of course aren't resting they are using the last of the feed and stretching out their roots while the medium "dries" out not really giving a chance to totally dry of course but the medium has time to push out the remaining elements to improve airation and root growth(water search)

then the next day start cycle again

i have high air exchange and higher temps than most use but w/ added blue and nutrient levels this will aid in proper transpiration for plants and if humidity is still an issue add a dehumidifier
i vent 1 400 into cfl balanced spectrum veg room to add dryer air to high humidity and increase temp alittle but all is vented out again at other end of room
trust me people hve rooooooms w/ soilmedium and no messy runoff everywhere
in fact plants will grow better and roots will exchange much better this way once the proper levels of watering are learned
i have seen more pics of this problem that problem most are a result of overwatering in the end
it will raise ph even on the slightest levels as a first indication
if you can weigh buckets and have the time i would do this
mix medium fill container and weigh it then record
little by little add water and mix to evenly distribute water throughout medium keep checking by taking handfulls and once it is moist enough it feels wet but isn't dripping it is ready weigh this it is important to remember
keep adding water right until the soil drips just alittle in hand
this was too much moisture record this weight for comparison to see how much it buffers moisture
now you know dry weight proper wet weight and over saturated weights
or buy a cheap 10$ moisture probe and check
i wouldn't really recomend just picking up containers because even by feel it is too easy to be way off at times slowing your plants uptakes
also should be mentioned i use landscape fabric containers to increase dry times and airation over a standard bucket that will dry out on bottom and top at dif rates
for smaller plants i have been using fabric reusable shopping bags that are less than 2$ and was using chicken wire for ridgidity but switched to a coulple of wraps of some electricians tape to stop buldging
must have good root level air flow to constantly reduce stagnant humidity and reduced evaporation levels from occuring
hope this helps alittle here and there

i am having the same rust looking spot on two of my girls. we talked about me having an overall ph problem most likely. but waht should i do with those two. do i try and regulate ph and hope the nutrients are there just not available to them at the current acidity? or do i try and fix ph AND go buy some calmag and feed them?

i honestly wish i could answer u bro im gonna have to post pics tomorrow i got back and those leaves are really progressing ...She is 53 days old and she is packing ....the seed stock says 6-75 but I havent seen 1 thread where she met that timing .....so what im doing is putting pis up in the cannabis infirmary to make sure but i have honestly looked at so many threads for all the problems i think i got her in check or she is gonna start cycling down ....noty sure she has been fed kinda heavy too but she can drink and this is my first problem with her look for the post tomorrow am when the pics come

Yo bro... picked you up on Forum-radar.. lol

you need to straighten out ph... flush 2-3 X the pot's volume with plain correctly ph'ed water... 6.3-6.5



you can fert em till the cows come home... but if ph is out... it doesnt help...

same with your body too by the way!




EDIT: Sorry for just bargin in swampman... where's my dern manners anyway?

 

[swampman]

dude JM ur always welcomed ......ALWAYS and i just love the shit u throw at me ......OK so i did plan on a plain watering next ......

Sativa Lover ....although im in the learning phase i really appreciate ur advise .....I havent checked or ran every single PH runoff just 1 every week but now seeing this from U i completely understand a lot better I was also told to water at different times to make sure u evenly get the coco fibers soaked it will basiclly just sheild off the water not absorbing it properly ....So now i got a pretty hetic job and just earned another with the ladies coming to a close


Saying this and seeing my total feeding schedule i can understand a lil more ...,....NO one has given me the idea of using actual weight scale so thanks i will be doing this for the next grwo .......

I have a planned better grow coming up as i have learned so much after the first grow and im sure i will still need coaching for the next few .....

I do have in mind to ease up on the feedings cause she is going amber hairs alrewady ......i hope they not actually burning now cause i have read that too


Here ARE MY next scheduled feeding....

Oh i have 5 gal and 3 gal ...
1 5 gal grow bag
'1 5 gal pot 12 in diameter
1 5 gal white bucket
1 3 gal plain white bucket

so they all gonna drink plain water no run off just to get them a lil tase of H2O

then a slight feeding of Seagrow 4-26-26 and 1/2 dose ......
then the MOlasses at half dose
then water plain and PH ......

also how many times should i actually use the stump tea its also a molasses, kelp, microbe shot sort to say a tea in itself .......


thANKS BOTH U GUYS >>>>>.ILL HAVE SOME PHOTOS IN THE AM !!!!!!

GOTCHA BRO i actually ran 1-1/2 gallons throught the BR 4 in the 5 gal grow bag tonight when i got home i checked the dirt and it was down to 6.0 .......and she used some water already she has been doing her thing but u can tell she is off cause i havent seen anything in a few days all the small buds are doing is getting veryyy fosty and sating thick .....tonight she had a few new leaf lets and seems the hairs really woke up ....they did make some progress .....now that i have read what sativa posted i friggen left extra water in the bottom of the drip containers cause i basiclly ran out for work .....she started to run to 6.5 after ust the 1-1/2 gal wash so i left it at that and waited till i got home ,......so maybe she has got her fix


As for Br1 i am pretty sure she is Mag def cause i went through everything before i took a peak and she hasnt been fed hardly any ever ......so let all have a lil :smokebuds: ans see what happens the next few but pleas guys check in and make sure i am keeping up the good buds .....ill put pics in the am they went night night !!!!!!!!

   some ideas which is better the flora lux seem perfect for the dimensions and the square footage i need cause ill have the flo and cfl from other sides ....4 plants in 1 gal should make some ahummmm nice buds as long as the proper yada yada goes on .....​

   just want you to have the facts to help support your decision
   it has been more than doccumented that blue spectrum does advance growth or it wouldn't be used at all in leds if it wasn't shown to increase growth not my 2cents worth more than well documented plus it isn't just about the blue spectrum it is usable energy in the end
   the cmh increases all aspects of spectrum and lowers heat output of bulb
   don't think you could really take somebodies opinion unless they have used one to actually compair like crop yields
   and alot of growers are switching over rooms full of theese and others are waiting banging at the door to create a 1000watt model like me
   but phillips doesn't know if it is a viable profit w/ all the advancements in the industry it cost 10,000s of thousands just to make a new box orientated towards horticulture and this is about the lowest cost for them
   i know personally alot of people that have bought 2 400s and used them to out yield 1 1000 watt w/ no problem and better product but for the most part they won't be taken seriously until people understand them better and understand the vast diff from other bulbs in the family
   sorta like once plasma inductoin lights are cheaper it will be a no brainer at which newest tech is the most beneficial
   good luck in your choice hope i helped you make a more educated decision about your issue​

"The HPS-Retro White lamps allowed us to change HPS fixtures to white light without replacing the fixtures. The 17% reduction in foot-candles has been compensated by the brighter light. The brighter lamps have eliminated shadows. HPS-Retro White has provided another tool for better lighting by just changing the lamp."

just want you to have the facts to help support your decision
it has been more than doccumented that blue spectrum does advance growth or it wouldn't be used at all in leds if it wasn't shown to increase growth not my 2cents worth more than well documented plus it isn't just about the blue spectrum it is usable energy in the end
the cmh increases all aspects of spectrum and lowers heat output of bulb
don't think you could really take somebodies opinion unless they have used one to actually compair like crop yields
and alot of growers are switching over rooms full of theese and others are waiting banging at the door to create a 1000watt model like me
but phillips doesn't know if it is a viable profit w/ all the advancements in the industry it cost 10,000s of thousands just to make a new box orientated towards horticulture and this is about the lowest cost for them
i know personally alot of people that have bought 2 400s and used them to out yield 1 1000 watt w/ no problem and better product but for the most part they won't be taken seriously until people understand them better and understand the vast diff from other bulbs in the family
sorta like once plasma inductoin lights are cheaper it will be a no brainer at which newest tech is the most beneficial
good luck in your choice hope i helped you make a more educated decision about your issue​

man you got my attention
