Hello and welcome to your show DGC. Wondering what is going on with these.. they have about 2-3 weeks left. Grown in 3 gallon fabric pots with coco loco. Mega Crop nutrients fed around recommended strength. HLG 600 rspec QBs @ 500 wall watts. Lights are about 18” from highest top. (Im maxed out for height and let these get too tall before flowering) LST is around 80-83f. C02 ran from 800-1200 ppm lights on.
I think that’s all the details, so what are they showing signs of? I am going on my 3rd year of growing and want to dial it in, I’ve been lucky and had minimal problems, I don’t know what to look for with deficiencies, toxicity etc. thanks!
