These plants were showing female after only 4-5 weeks under 24/0, so I switched to 18/6 and added some light. I used Age Old Grow half diluted (with some local spring water from this hippy co-op grocery store) from 3 weeks into 24/0 and have been using Fox Farm Ocean Forest soil. I did 18/6 for two more weeks, at which time they were already essentially flowering at the very tops. I got the 150W HPS and switched over to 12/12. I'm now using Age Old Bloom half diluted. I keep the temperature around 78-80 during the day and around 68 at night with humidity fluctuating between 30-50%. I'll admit.... I've never tested the ph of the soil.
They seem to have some decent buds forming...
