Quick question my friend has 3 Northern lights autos and 1 Jack 47 auto under 300w led lights but the don’t seem to have much growth in them,. Jack 47 is biobizz all.mix medium and feeding only when dried out completely whilst the northern lights are in coco and again feeding when dry, the water temps and medium temps are okay same as humidity and temperature. Could the slow growth be from poor leds and would adding a 600w hps light into the tent help benefit the grow?
