I was getting some discoloring, necrosis, and curling of fan leaves on Anna which indicated a potential nutrient lockout. Considering the amount of salt built up on the smart pot and my lack getting a substantial runoff during each watering makes me think there could be some salt builtup on the roots that is causing some issue. Will continue to monitor and do a semi-flush next watering.
Hey mate, careful with those Quantum Boards at that strength. For comparison i run a single Qb288 and it's enough for 3 plants, in fact i turn it down to 90-100w while vegging. Check out their website and check the par ratings for your board's, you should be able to find some pictures of the different ratings around a 2x2 space. You're aiming for no more than 600umol during veg, which i get at 18" at 100w.Also the leaves look very droopy, are they getting overwatered? Ive always used soiless so im unsure about nutrients in super soil, but i can make out some burnt tips on your leaves, maybe the soil is too "hot"?Anyway man, good luck with the grow!
