First grow, first post, no questions till now. She's a bagseed -killer bud mostly sativa strain, I m 6 1/2 in flowering. I have 300w hps overhead and 4 23w cfls (2700k) at the sides. I use foxfarm nutes. veg nutes when veg, now flowering nutes. I have no problem with foxfarm nutes. It stop growing up and started fatten 3 weeks ago. But, I noticed couple of days ago it has grown new flowers on all tippity tops. the flowers all have pistils. Its growing more and more. I feed it flowering nutes once a week. full strength. full strength causing to grow up? Anybody knows what going on? Is this normal?

Ya mon, normal.

It's quite normal. Your plant will continue to grow tall as well. As long as everything stays green and grows, yer doin fine.

Its definitely all green no burns. Thanks alot guys. just getting nervous toward the end. Don't want mess up. Its been going so great. 4-5 more weeks to go . the pistils are still white.
