I think I have an idea what her problem is, but I don't want to influence anyone's opinion. Soil grow Temperature is maintained at 76 -- 78 F Distilled water Fox Farm Grow Big Nutes HPS 400W light on an 18/6 schedule. 38" tall on 5/26 and was 23" on 5/3 Indica / Sativa hybrid (Caramelicious from Amsterdam Marijuana Seeds) (BTW: they suggest the plant's max height is 65cm or 26.6", which she has exceeded by a foot) pH has been fluctuating due to grower's inexperience (5.8 on 5/3, 6.1 on 5/11, 6.8 on 5/15, 6.2 on 5/19, 7.0 on 5/22, 6.8 on 5/26). Water schedule is about 450ml per week spread over three applications. One is straight water, one is water + Epsom Salts, one is water + fertilizer. The watering is applied in the dish under the pot in order to keep the top soil dry to discourage gnats from nesting. All except the last watering was absorbed within 5 minutes. The last feeding took about 2 hours to absorb into the soil. The grow room is an extra bedroom with a ceiling fan on the lower floor of the house. The fan is on low 24/7 to provide adequate air circulation. The leaves are sprayed with distilled water once or twice a day. Her photos are attached. I can provide more if desired.
