Heat stress/low humidity or lack of nutes?

[BernieLomax]

Goodevening AFN.

My plants are starting to look even worse late, they have a some pretty good nitro and cal/mag deficiency and i started to give them some bloom nutes, and then they started to get a little colour back in the leafes, but now all the leafes are dying and getting dry, i dont know if it is heat stress, it looks a little extreme for heat stress.
Or could it be because of a new or the old cal/mag/nitro def?
I know for fact the temp is too high and the humid is too low, but is it enough to mess it up like this?

I dont have any other pictures at the moment, sorry guys

What is the temperature and humidity? (If you don't have a hygrometer in your grow area, you should get one. They're about $12US.

How old is your plant? It looks like it's starting its end-of-life thing, fan leaves yellowing, etc. Like you're close to starting the 2-week "cleanse" (water only).

I don't have much experience. Just thought I'd post my thoughts while you wait for more expert opinions.

The plants are only in the early week 7.
Temperature is around 32c with the tent closed, 28 when the tent is opened.
Humidity was around 25-28% way too low, but they other day it was way down around 15! I have tried to put water in there and stuff but it doesnt really help much.

I agree, 49 days sounds early for end-of-life yellowing. Do you supplement silica? That seems to make the plants tougher and more tolerant of heat, cold, etc. My plants are at 20%-30% RH and up to 31c (88f) during the day. They're doing fine. Maybe they'd do better at a cooler temperature and higher humidity. But, they're not showing signs of stress. (Could be strain dependent, but that's one comparison.).

Hopefully namvet will comment. I'm a relative newbie and don't have much more to add.

 

[BernieLomax]

No i have never heard about Silica, i dont have anything to add except my powder feeding for bloom, im waiting for some epsom salts that should be with the mail tomorow, for the cal/mag.

it is my first grow so errors will be made for sure, im gonna get a humidifier for my next grow.

and thank you for your input, newbie or not

Hey brother.Welcome first off.As for your yellowing I couldnt open the pic.site is havin an issue atm.it'll be fine before long.

if its a true 60 day satrain your right on the line of it being right on imo.BUT,if its not you have an issue somewhere.ill let the awesomes come rollin though for that.but silica will really help with the heat issues and CO2 will too.those help withsatnd heat stresses really well.but temp dip donw your Rh will shoot up pretty good some times.As long as some air is moving it should be ok.Smal fan,something.And more air for higher heat should be employed too imo just watch for wind burn on the leaves.

if yer nutes are really old,might be that.But they need N looks like too.Id mix a bloom and cal and N batch.PH ok?!Im an organic guy so nutes aint my strong suit though.be good bernie!! Are ya dead?!!

LMFAo Bernie Lomax..damn Im old LMAO!!"AFN smoke out"

 

[BernieLomax]

Haha, im alive when the music is playing bro!
Im on a hunt for the treasure for the mobu.

Supposibly they should be done in 70 days they say.
I dont really have any fans i can add to the tent or money for one at the moment, but i will get a bigger fan for my next grow.
My nutes are about one year old, might be too much.. got them from a friend of mine that didnt use them.
I am currently waiting for some better nutes, Advanced nutrients PH perfect, Bloom and micro.
I dont know my ph at the moment because i dont own a meter for that.

Thank you for your input.

Bernie Lomax :roflcry: maaan, I just chuckle everytime I see that.I spent my early years watchin that and first used LSD watching Howard the Duck.NOW THATS A RIDE!!lemme tell ya!!

Do you have or can you get any hardwood wood ash??if so mix some of that in with your watering.that'll provide Silica for you plant.Run CO2 if you can too.But PH perfect is prety good from what ive heard.keeps PH pretty stable.Your RH is fine.dont sweat the RH unless it gets above 20% cuz of late flower.can lead to mold n fungus issues sometimes.ESP. with no fan.it should be lower imo. with no fan.

the bes advice I can offer you brother is hit it with a 50% of Nitrogen 50% bloom and a full dose of cal mag.But short of that.ask in the 24/7 help thread.there some very knowledgeble gowers there.Just for this occassion.Be good bernie dude,Hpe ya find the Mobu man.LOL!

 

[BernieLomax]

Haha, Sounds pretty fun, never did LSD tho, im sticking to my weed
But no judging tho, i dont mind people trying off stuff and having fun.

Im not sure exactly what hardwood wood ash is, only thing google tells me is... well, ashes from burned wood, i can always burn some haha.
I do have some small fans in my tent but i dont think the air circulation is the best.

I have one 100mm exhaust fan and the same for intake, and i have 2 more blowing air on the plants, but not much circulation in those i think.

eh I was 18 er so soo I hought HEY WHY NOT!!it was a frigin blast.wouldnt touch the stuff today.well maybe a truffle if I get back to the EU anytime.

But hey if its all ya got bro its air moving.And thats exactly it man.Wood Ash fro hard woods.mix in a few teaspoon per gallon of good clean flitered water and bubble i if you can.if not no biggie.just adjust the PH if you can too.it'll help.that goes a long way to helping you plants.in all honesty ya should do that after the first couple weeks,but no worries.Silica and CO2 go a loooong looong way to help with strees of all sorts esp. heat.

Heck Ive been shot with saltrock in Florida when I used to shroom for a livng.LMFAO!!that sucked!all three times ive been hit.LMAO!!
