8 x Northern Lights Fem AF

GROW DAY 22 (day 1 of wk 4) Had some heat issues in the tent, max day temperatures were around 30-32C, so I added a inline fan to the intake tube also. This helped to bring the day temperatures down to around 26C and the night temperature is around 16-17C thanks to the thermostat heater. Watered with 1l/plant. Drainage seems to be working, had around 2dl runoff, so I guess 0,6-0,8l will be enough water next time, after 3-4 days from now. GROW DAY 25 (day 4 of wk 4) Did some more LST to get some more light for the lower branches. Bent some of the plants and for some just moved the larger leaves out of the way. GROW DAY 26 (day 5 of wk 4) Watered with 0,6l/plant along with this weeks nutrients. Still had some drainage, so maybe 0,5l does the trick next time. I figured the humidity in the tent is too low partly due to the quite effective ventilation. Decided to order a humidifier and control units for it and for my inline fans. Looking forward on them to come so I can rig the up. GROW DAY 28 (day 7 of wk 4) Visited a local grow shop to get some supplies as I´m planning on trying for some chili growing on the side. I´ve grown chilies before, but nothing too serious. On that shop visit, I also got some Alc-a-mic, Activera and Leaf Coat, all from Biobizz. Going to apply the first two with tomorrows watering. As for the leaf coat, I already tried spraying it. You´re supposed to use it once/week to fend of pests and other nasty things which are after my precious plants. It formed a wax kinda film on the leaves with a glossy finish. Let´s see how it works out:) One plant is showing signs of a nutrient burn (my initial diagnosis). Seems like couple of leaves are goners, but otherwise it seems to be doing fine. Ps. When looking at todays pictures, I noticed signs of nitrogen toxicity on the leaves (clawing). Will leave Bio-Grow out of the mix when watering tomorrow.
