Hi all.

Was just wondering if this is due to some sort of Nutrient deficiency. My guess would be a Potassium (K) deficiency from what I have read.

Anyone else know whats up with this?

Temperature is only around 75 - 85 max! Plus, there are other plants in the same room that are not displaying these symptoms and they are all fed the same.

Could possibly be slight nute burn, however I only nute at 1/4 of the recommended dosage.

the npk value is 15-13.1-12.4? is that the time release in the soil? i'm unfamiliar with that particular formula...

I switched from shit generic potting mix to miracle grow mix and sand combo. Also after switching to Foxfarm big bloom, I noticed a large jump in growth over m'g. started flowering today with a modified hps security lite.
party on!!!

Judging from how dark the leaves are, it's probably nute burn. Marijuana is *really* sensitive to nutrients - I'd say much more than any other plants I've grown are. Had to learn that the hard way. :-P
