Last grow was in soil and standard plastic pots. This grow is in 70 coco / 30 perlite in Airpots. The soil grow, I basically did nothing - no temperature or moisture control, no PH balancing and the standard feed schedule (albeit feeding when the top soil was dry instead of daily). The only issue I had with the last grow was fungus gnats. This grow, I've had no pest issues yet. But the change to coco with airpots opened up some new challenges as I'm finding out with this issue.
Should also mention that I changed the light from a cheap LED to a Spiderfarm 1000 which is now on 24/7. I have it at about 80% power just now and around 20" from the top of the plant. Ventilation is good. Humidity, I'm going to adjust by adding a humidifier (tomorrow hopefully) because it's lower than it should be. Again though, the first grow I had no issue with humidity.
Also, the strain is different this time which I think is partially to blame. Last time was White Widow Auto. This time it's Auto Kryptonite (a 'dwarf' plant).
