Here is my major plant, topped 3 weeks ago. Grown in MG potting soil with perlite, bat quano, and worm castings added. About 6 weeks old, started under cfls for the first 4 weeks (grew slowly). Then switched to a 600 watt hps (grew much faster). Had a few heat issues ran at about 90 degrees f got that fixed now, about 80 f now. She has 4 main colas from using Uncle Ben's topping technique. Thanks Uncle Ben and RUI!! My question is, should I start foliar feeding her with my 1/4 strength seaweed, fish emulsion spray? When to feed, during it's 18/6 light cycle? And how often to feed? Any help would be verywelcome. BTW, I only have to water her about once a week or less because I use a moisture meter and I know how horrible overwatering is to my plants, I killed her twin by overwatering, causing nute lock-up, root rot, and general disaster. That is why I will only use foliar feeding, and soil watering, because the soil mix has some nutes already. My NPK levels in my soil are very good at this point.
