Nute burn? Nitrogen Def?

[Thunderfingers]

Bagseed grown under 2 75w CFL's. Plants have been doing great for a first time experiment but one of the plants seems to be headed south. I've been using a 20-20-20 mixture once a week. i switched to plain water a week and a half ago and havent seen much improvement except in the very top of the plant. I switched to a 12/12 cycle about 3 days ago. Any suggestions? Should I flush the plant?

When in doubt flush it out....looks like your N is not low at all. There is some sort of problem though, I think that looks like a zinc deficiency. Flush with PHed water and feed with a balanced nutrient. I use hydro nutes added to PH water for my soil ones. Make sure all the plants needs are addressed.

thanks very much for the reply. Can you elaborate on the "well balanced nutrient part"? I'm a noob in the worst way!
