The leaves from the bottoms are turning yellow at the tips and curling up, I have flushed both plants and it seemed to have work for one but not the other is this nute burn or what?? Pics coming soon
It's hard to say, to me the yellow leaves look like a bit of nitrogen def. but when the tips dry it up could be nute burn. What type of nutes are you using?
I wouldn't worry about it too much, looks healthy and about the right size for 21 days. Just go easy on the nutes for a few days. Happy frog has plenty of nitrogen so I doubt it's a N deficiency.
I have a 39x39x79 grow tent, 4" inline fan for exhaust with a jr. carbon filter, and a 6" inline duct booster for intake along with a 6" clip on fan... My Lamp is 400w hps with an easycool reflector hood.
i figured it was too early after the factthats why i flushed them but i dont veg for very long anyways just cos of my situation I cant veg for 4-7 weeks like ive heard other people doing so ive never been sure when to start nutes
