Personally I would pull those leaves aka defoliation, then feed lite 1-1-1 npk. Looks good tho still really heathy.

Slowed growth, yellowing top fan leaves
Any suggestions as to what my plant may be deficient in here? I have been feeding very minimally with less than the recommended amount every other week. Nutrients I am using are biobizz fish mix, bio bloom and top max with just some cheap compost soil.

What's wrong with my seedling?
I don't understand why there is something strange in the leaves of this seedling. It happened to me for the first time, even though I was always raised in the same technique. As a fertilizer I just added 0.5 ml to 1 liter of biobizz grow.

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake
