I have 48inchesX48inchesX78inches tent. I had 2 ak autos 35 days old and 2 nlXbg 21 days old under 400 hps. Just got new digital 1000. First day ran on 5O% day 2 75% day 3 100%. Hooked up to fan and temp in low to mid 70's. Light about 18 inches away in cool hood. Plant leaves started growing oddly, really thick on one side and started to get the crinkle/twisted look. Today I backed light down to 75%. Are they just too young for that much light or what am I doing wrong? Thanks for any help
