Day 21 with new equipment ran into some probs any suggestions??

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

here are some pics

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?

humboldt nutes conventional 3-part the whole line except for ProZyme

What type of soil? Most soil mixes have plenty of nutrients for young plants they just need plain water for the first 3-4 weeks.

happy frog, i didnt use nutes til the 15th day which may have been the problem but i flushed them out and problem still persists on one of them.

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.

Imho 15 days to early for nutes . I use pro- mix and dont add nute till at least 3-4 nodes, just my opinion

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
