Grow #1: White Widow Automatic

[Day 15] Upgraded from 60 to 80 Watt LED panel (will use both later) and started using Vita Race today. [Day 16] Topped the plants main stem. Also sprayed some water on the leafs, to get the spots left by the Vita Race off. [Day 17] Started measuring Ph and EC level and noticed they were way off. Will only use water the next 1 or 2 days and use less fertilizer. [Day 18] Also added a second light panel (60+80 Watts) and upgraded my ventilation from 100mm (100m3/h) to 125mm (185m3/h). [Day 19] Started LST by tying the plant down with a bit o help string. Topping seems to have worked. [Day 20] Will give it some fertilizer today. pH and EC is going into the right direction again.
