This is the second veg stage for this gal, but she's 4 weeks its about 85-90 but not sure my temp gauge is broke. But I am using CFLs 2-3 inches from the top and a few on the sides. The yellowing is not bad but you can see it. Any advice?

Could be a number of issues, pic 3 shows twisting leaves...a sign of moisture stress.

You are either over or under watering, and/or over or under feeding.

And if you're temp gauge is anything close to an accurate reading, temps are too high...should be at 78.

Yeah but if I'm over feeding wont I get a nut burn? And or drooping leaves from over or under water? Maybe heat stress, that's all I can think of but I'm still learning so idk.

Click to expand...

Over watering was my first thought yesterday, that and heat stress will cause leaves to droop.

Yet there's a leaf in the backround on pic 4 that doesn't match overwatering/heat stress...looks like a grasshopper got to it.

Picture #3 looks like heat stress - the leaves are curling up. Do they feel crispy?

Let us know what you are using for nutrients - also, what is your air circulation like? Do you have circulation fans? Intake? Exhaust?

No intake and exhaust. But I have a fan in there. The leaves feel a little dry not crispy oven keen using MG
nutes and the first two grows went excellent and same with this plants first veg. Went great.
