dear watsei,
by your experience are the flowers okey or are the becoming trans its now 12 weeks just switched to 12/12 lights are led full spectrum and 1 hid 400 watts, feeding once every other watering but i stopped due to the nitrogen burn, is the flowers okey or no for 12 weeks old temp are between 22-27 c humidty between 40-60
The don't look to bad. They may be a little root bound and would probably benefit from bigger pots.
They've just entered flower. Maybe just decrease to every third watering with the feeding? Either that or decrease the strength of the feed. Many people feed with every watering, some every other and others feed->feed->water.
I feed pretty low in containers. Maybe top out at 0.6-0.8 EC(every watering with a little runoff). You're on the right track when you're looking at the plant response and adjust feeding accordingly. That's the proper way of dialing in your environment.
Good luck in your endeavors, you're on the right track! Cheers!
