My plants are about 6 weeks old and undersized cuz I stunted them by accident. I used FloraNova 7-4-10 the last couple of waterings not realizing I should of been using it the whole time. I put them under the 1000W MH about 5 days ago. Alot of my plants have yellowing on them that I assume is from N deficiency. Should I start using some stronger Nutes? If so what combination should I use? Thanx.
