Well bottom leaves are yellowing and coming off. it started when one plant had a slight claw on it, 2 days later it looks like this
I didn't think it was a nitrogen deficiency they to young and good soil don't make sense to me.

Plant looks too big for that cup.

I know its that time to transplant, im waiting till I get this figured wasn't trying to add any more stress to em.

It may be the reason though.

Then ill transplant now just in case that's what it is.

Honestly don’t need to add much to fox farm ocean forest my man it is specifically designed to carry your plant well into bloom without adding to many nutes to it... all I do is add a bit of dolomite lime to the soil and only add nutrients when plant shows def... worm castings may be giving your plant too much of one nutrient and in turn looking out another... I’d transplant into just fox farm ocean forest and just do a microbial tea with earth worm castings when needed.... good luck

Welp done allready replanted them yesterday in the same mixture fml, so I just changed all the soil out very carefully for pure fox farms, lucky I had exactly enough left to the last drop worked out perfect. Hopefully this will help.
