Nutrient feed at half strength this week. I have tied as many colas up with string for support. Filtered tap water only now. Found mites on one plant at the back. Predatory mites on the Ready, they work for me!
Ive decided against the hps and added another 315w LEC, so there is now 3 315 LEC in total. 2x 3100k and 1x 4200k. The temps are lower using LEC than using a hps even with an air cooled reflector.
