indoor small soil grow

So i'm about 5-6 weeks in... The tips seem a tiny tiny bit yellow, and the top leaves look stiff, bubbly, ruff, like heat damage or light damage almost. I have a 150w HPS about 21 inches up (moved up from 16-17"). I have 2 fans blowing directly on light and the temperature next to the plant is 80 degrees. Help!!!!! Should I check the pH maybe? I have 2 plants in one pot too is that bad?

2 in 1 is bad, not sure about ur other problem

any pictures? they would help

It's not light burn or pH. You can't have 2 plants in one pot. I know it seems like you should be able to, but you can't. I don't know why. It sucks but you need to start over with separate pots. You could cut one now and hope the other one improves, but honestly that is pretty unlikely. Chalk it up to experience.

this guy runs more than one plant per pot. he flowers really early though. and he said he makes out fine.

read down where he said he had 3 plants in a 5 qt pot, flowered at 8 inches and got 10 grams each plant, 30 in all. sounds like it could work to me, just as long as you flower early.

how often do you give them nutes?
