My leaves are droopy, and on a couple of the plants the leaves at the bottom are yellowing. I see a plant with curled up edges on the fan leaves. What gives?

what are your temps? if its too hot than that is probably it.

have you calibrated your pH meter lately?

my last pH meter almost screwed up the whole grow.

now i have a new one. start by calibrating all of your meters, then troubleshoot. you need to know where you are before adjusting anything.

a picture would really help.

20% humidity for veg is a little low

keep your hopes up here my lifestar

What is your rez temp? any chance your ph has been fluctuating alot? Hope she pulls through for you. Peace

 

[Growdoc]

Your Ph is to high and this is causeing lock up, some nutes are to avaliable and some not at all...

Drop your PH down to 5.5 and use some root juice in the next res mix, this should bring them around..

Also your ppm and EC are to low for optimal growth, raise them up...

The Lifestar seems somewhat more heat stress prone than some of my others. BOG

 

[Growdoc]

is she really sensetive BOG???

[BushyOldGrower]

Well, I have some leaves with curling edges too but not certain its from heat stress or not. BOG

What else causes lengthwise edge curling? PH?

I tend to run on the alkaline side of perfect.

 

[Growdoc]

a lock out of N can cause an overdose of P and K.

to much K can make leafs curl upward..

my 2 cents...

Thanks so very much for all of your help.

Growdoc: I lowered my ph to 5.5, what should my ppm's and ec read?

Bog: what parameters do you suggest??

 

[Growdoc]
