OK I have a problem I cannot figure out. I have an auto flower in FFOF that was pre dolomite limed and all waterings were phd to 6.5. It's roughly 5 weeks old have only given nutes the past week. Very low dose nutes probly 300-400 ppm. Have had temperature problems dropping into the 50s on some occasion when lights out. As of now I think I have a deficiency problem. Originally I had a heat stress problem with the light to close but that was 3 weeks ago. I moved light and added nutes I now think it's a nitrogen deficiency bcus of the twisting of new growth. And lower growth tips turned up and dieing off. It has experienced rapid growth in the past 2 weeks and I think I just didn't have enough nutes in the soil at the time of this growth. Thanks for any help.
