I have these brown spots starting to pop up on the plants. It is day 23 of the grow. It is mr seedsman zkittlez auto fem seeds. I’m using general hydroponics nutrients. 2 ml /gal. Micro and gro 2.5 ml /gal. Bloom 1 ml/gal. I added worm castings to the fox farm coco perl 70/30 mix before the grow. I think that is throwing off my runoff readings. I was at 200 ppm in but over 2000 ppm after. the website said that this strain sucks up nutrients so a couple of days ago I started using the same amount of nutrients but using less than a gallon of water because Ibwas always having way too much. I am under two viparspecra 450 lights about 26” above the canopy.
