What ppm should I be hitting about this time ?Underfed in general I think. There are some links in my sig to deficiency
Yeah the humidity was low during seedling.magnesium and/or ph. if its just a few leafs it could be because of wrong humdity at the seedling stage.if you are after the seedling faze then you should feed.
how do you feed?
Saw that too and got scared but under a microscope they are trichs. Idk how they are even there so earlyWhat are those white dots on the fan leaves in pictures 2 and 3? Trichs or bugs?
They are in small 4inch pots. I was trying this run to flower in 1gal pots but now they are yellowing more with brown spots so I think you are right and I’ll have to pot upNeed potted up maybe if they are in small pots
