I re-read your posts & to see if you're hydroponic or soil. We need to know which before we can help you with your nutrients. Also there are hundreds of nutrients out there, so unless one of us has used your particular brand???? The best thing is to read the package instructions. Whats the NPK? Organic? I'm using a cell phone, so pics are sm, but from what I could see, doesn't look bad, maybe only a tad dried out on just the very edges of a couple of leaves. Don't ever pinch off your main bud unless it's already dead. You'd be seriously shorting yourself on bud wt at harvest time. Do you have any side lighting in addition to the 400hps? I like to throw in some fluorescents on the side to give some light to the undersides of the buds. Helps plump them up. There have been times when I've had to harvest the main bud & leave the lower ones to go longer to plump up & ripen, being farther from the light & somewhat shaded by the main bud. The side lighting helps the lower ones keep up a little. Just a sugestion, but not necessary. I have some suggestion for you just before harvest, but won't over load you with that now. Keep posting so I'll know when you're ready for that, & so we can help you over any more bumps in the road you may encounter. Just remember, as long as the stems haven't turned woody, you can bend & tie down as needed.
