This is my second grow. Got a question....i checked the trics on my plants and they are about 50/50 cloudy/clear....no amber that i can see yet. The top 2 inches of my biggest plant seems to be drying out while the rest of the plant seems fine. Is this drying out a problem? Wodnering if I should harvest. Its bag seed and looks mainly sativa. Under 400 hps with 4 13 w cfls. Flushed on week 7, no nutes since. Ordered some seeds, hindu kush..anyone with knowledge of this strain, appreciate any tips, thanbks.
