Flipped to 12/12 light schedule. Swapped MH to 400w HPS. Female flowers visible on all three. Eugene(Wembely) and Herschel(Glueberry OG) are both much lankier than Beth(Strawberry Shortcake). Beth definitely looks like an indica.
Hey chef, I suggest to inspect Herschel and the others plants, it isn't Cal/Mag deficiency, it seriously look like spider mites bites.
Check all the others leaves, the first leave infected is a kind of first base where they eat and reproduce then the colony moves and females start to let their eggs a lil bit everywhere.
This leave is the first sign of an invasion, and the first wave looks to be massive as your leave have been bitten on the 5 fans on all the veins from the petiole to the tip.
I seriously hope I'm wrong ..... but start your full inspection, if I'm right I suggest you Sierra Natural Science SNS 217.
@WeedishChef,alright, by the spectrum I wasn't sure if it was MH or CMH.
These plants are 100% healthy, not even 1 tips burn, no purpling stems, they're perfect π
@Bigpun, Thanks Bigpun. I almost messed this grow up because of my misdiagnosed bug problem. They all recovered nicely though. I'll be posting harvest pics shortly.
