8 x Northern Lights Fem AF

GROW DAY 8 (day 1 of wk 2) Had some issues with timers, temperature variations and such, but now with them sorted out and the bulb changed to the more vegetation-appriorpriate Sunmaster Cool, I think we´re good to go and start some serious vegetation growing. Just watered the plants with water (0,2l/plant) and the nutrients listed in the nutrient section. Also added some coffee grounds on top of the soil before watering. Not sure if this is going to make any difference, but I figured it´s worth a shot. I've sprayed the plants 2-3 times a day with water and also the outsides of the pots within reason to increase air humidity in the tent, which tends to be on the low side. GROW DAY 12 (day 5 of wk 2) I was away for couple of days and rigged couple of 10W plant lights as a backup in case my primary light/timer would quit on me. This way the plants would received significantly less light for some time, but wouldn´t be in complete darkness. Upon returning from a short Xmas trip, I was glad to notice the primary light worked perfectly. Some of the plants showed what I figured was slight heat stress, but otherwise every plant is growing on its own steady pace. Watered for the second time this week (last 0,4l/plant was 4 days ago) along with the nutrients mentioned in the nutrient section. GROW DAY 13 (day 6 of wk 2) Nothing special. Still bit of heat stress. Continued to spray couple of times a day. Humidity still a bit low for my taste, around 45-55%. GROW DAY 14 (day 7 of wk 2) More plants were showing stress signs, so I moved the lights up a bit, not at 60 cm above the canopy again. Also added numbering on the pots to make progress followup easier and moved pots in the middle to the sides and vice versa.
