3.30-4.1: Week 10. Days 67-69. Trichomes 50/50 clear/milky. A few random ambers. Leaves are fading but still feeding 1/4 strength. Maybe a week or 2?
4.2-4.5: days 70-73. Moving along nicely. Trich's more milky than clear. Stopped feeding and only water.
I really appreciate your grow diary!! I'm on first grow and alos using the xs1500pro and everything was great but I also notcied the white tips around week 4/5. I've searched high and low for other users with this light. Right now I have it at top of the tent on 100% so about 30 inches away from tallest plant. I did have it about 18 inches on 80% but definitely had some light stress going on. I would like to run a couple few plants at different stages so that is why I'm testing the light where it is. I've noticed several users of this light reporting white or yellow tips on top growth. I'm also running 20/4
@Heretic, i'm shooting from the hip here but i'd guess somewhere in the 375-450 range. At the time of this response, i'm at 12 inches from top of the plant at 50% power or 75 watts. if you check the light's specs, 50% power at 12 inches should be somewhere in the 400 ppfd range.
