Indoor Auto white widow grow need help please!!

i'd say heat stress and light a bit close too fast... keep the light baked off and monitor temps... 78 is ideal... anything over 85 is bad.... plants stop transpiring and cant pull mass flow of nutrients / etc up because of it.

As for the 600w hps I think they will get a boost when you get that on will need red spectrum for flowering. I have my larger plants round the outside with my 600w 12 inches above roughly and my younger plants in the middle as there shorter at the moment about 22 inch away. If it's not dual spectrum would probs be a good idea have a couple the cfls in there as well if there blue spectrum. Or even better have the Mh aswel if can control temps. Don't wanna think bout the cost of that tho probs isn't worth it haha

yeah hps is more lumens too and great for flowering... but be PREPARED to PROPERLY cool that grow area... that means maintaining 80 deg F max... 60 deg F min at night... and 40 - 60 % Relative humidity. this can be quite difficult depnding on your environment.

If there is a strong breeze it can also give a similar effect sometimes. Just looks exactly like one I had will try and find a pic. If your run of is 6.5 that should be ok actually but going into flowering plant will start using more phosphorus aswel Wich is easier to uptake at slightly higher ph same goes for calcium and magnesium. I would suggest just giving your usual amount of water with light nutes if you have a fan on it direct it away a bit. Do you now your humidity?

fantastic advice also btw..

applies for both heat and light:


hold 24 for 1st week... could even bump to 30 ... then slide back in 2 inches a day or so... condition them to its intensity...never closer than 18 with 600 watts hps IMHO

Do take my ph advice and so on with a grain of salt I'm not an experienced grower. I'm confident in the lighting though if yours is cooled should be fine mine isn't. And I've had the 600w hps from seed with no heat stress temps been a steady 80f on 20 4 light cycle.

Here is a pic of myn that had nutes burn I basically just gave to much to early. Gave the next to waters with only a quarter my usual strength and sorted itself of its should catch back up in terms of size if you can resolve issues will just end up finishing a bit later as it take time to recover.

the run off is 6.4-6.5... Is this good??

on ph... should be able to water in adnd out at this... if you're in at 6.0 and out at 6.4 - 6.4 your soil is in the 6.8 or 6.9 range...

not bad... but needs to continue adjusting like you are until you get 6.4 in and 6.4 out.

as plants get older thei nutrient needs go up and change dramatically... be ready to supply their needs.

heres a ph chart..

Here's my tent now the bottom left is that weedy looking one that I burnt came back fatter and bushier but is behind on bud production. What you guys think the back 3 are on day 1 of week 6 from germination seem to be racing along especially the one back middle. The others are staggered at pretty random times to be fair just trying get the most out of my area without getting crazily overcrowded

i think it's some form of nutrient or ph issue rather than the light. If there is a strong breeze it can also give a similar effect sometimes. Just looks exactly like one i had will try and find a pic. If your run of is 6.5 that should be ok actually but going into flowering plant will start using more phosphorus aswel wich is easier to uptake at slightly higher ph same goes for calcium and magnesium. I would suggest just giving your usual amount of water with light nutes if you have a fan on it direct it away a bit. Do you now your humidity?

i just checked my run off and the ph was 5.3!!!!!!!!! So i flushed the pots and the ph is now 6.5.. Is that good??? And my humidity is 50%

MY TEMPS NEVER GO OVER 79DEGREES AND NEVER BELOW 60 BUT I HAVE 2 600watt lights im gonna put an hps bulb in one and leave the MH in the other... SO IF MY TEMPS CLIMB CUZ OF IT I HAVE AN A/C in there... ALSO MY LIGHTS ARE AIR COOLED WITH A 600FAN .... and humidity is usually around 50% THANK U FOR THE ADVICE!!! I JUST FLUSHED THEM!!! THE RUN O WAS 5.3!!! SO I THINK THAT WAS THE PROBLEM.. I HOPE SO ANYWAYS...................
