    Hey all- just canvassing to see what folks think this might be- deficiency? Currently running foxfarms, roots organics, orca, calmag, phd to 6.3, ec about 1.1 to 1.3 (1100-1300 us). I picked up some dr repair micro nutes and mammoth p (iron), just in the advent it's a metals issue?? Select leaves only at this point. While i realize this clone is way overdue for transplanting (just taken care of that actually), i don't think that's the issue and not too worried, as i saw this on my last run on the same strain and wasn't a major issue.... it seems like some older growth has an almost iridescent dark blue color as a precursor...

    More early stage:

    What’s the new growth like? A pic would be nice.

    Copper is harder absorb for the plant if the medium is too dry I believe.

    that doesn't look like copper or iron to me, looks more like Manganese, or maybe phosphorous

    Appears to be a P deficiency. Since you just transplanted you probably just took care of the problem.

    @blake9999 Lol, yup! Just transplanted last night. :) I was actually intentionally neglecting these, trying to stunt a bit to get a rotation going, and figured that was part of the problem for sure... i have 9 clones the same age, transplanted 4 about two weeks ago, and those ones are exploding bigtime... so i think I've established enough of a lag on the other 5. Between that and some planned super cropping on the 5, i think ill have two very nice harvests back-to-back :)

    They are a little too small for the EC you are dropping on them. Cut it in half and take it up slowly as they get bigger. Less is more with small plants. Transplant may be all they needed.

    Upped my calmag and added some bloom for extra P and K... almost 24hr improvements... :) it's this chocolate mint og strain, seems to be a lot more sensitive compared to the blue dream....
