Plants seem to be growing slow, these are the results after 3 weeks from germ to till and 1 week after transplant into ebb n flow system with ph balanced rockwool at 5.6 (soaked for 24 hours then transplanted) The second one is really short ( which i want, but it has dried shriveled edges but still growing fine it seems) the third has a yellow spot in between the veins, the first has one leaf just pointing down, and it the 6th one's leaves are kinda curling under. PLEASE!!! feedback on my plants would be needed, let me know if im doing something wrong or im just paranoid and they're doing fine. additional info I have, the current water is at ph of 6.2 with ppm of 930, nutes im using are the GH 3 part bloom, boost, and grow, room temp is at a steady 73, light cycle 18 hours with a mh bulb 600 watt, watering cycle is 15 intervals every 4 hours. The lights are about 12 inches, and maybe i should lower it a lil bit huh
