Okay, given the feedback, I purchased a 400 watt hortilux HPS and also a hydro hut 4X4 for growing (has white reflective coating inside). Also installed a reflector with a fan to remove the heat. The plants look pretty bad, i don't have a picture, but they have turned yellow, all the new growth, the old growth - large fan leaves look fine. Yellow new growth on the bottom and top of the plant, all the white hairs are fine, but all the leaves around the buds are also yellow. The PH is fine, 5.8, the nutes are general hydro, ppm is fine (1100-1400), i change them every 2 weeks, all i can think of is in the beginning the temps went up to over 95 degrees until i got the fans installed (for 2-4 days), and the new HPS lights - maybe this shocked the plants? This new light vs the CFL lights? Will try to get some pictures.
quinn Reviewed by quinn on . to close to light - what to do? Hello, have 2 beautiful plants growing, atomic northern lights. These 2 plants are growing in hydro, for about 6 weeks now, been in flowering mode for 2 weeks. The problem i have is they continue to grow taller, even though i topped them using the FIM method. Should i continue to keep moving the lights up? I am hesitant as the foliage down below (see pictures) will continue to get less and less light. Some of the leaves next to the lights are burning (turning brown). Rating: 5
