Maturing early?

Can anyone help? i have been growing whiteberry for a while now, but i just got a 400HPS system and im used to High Output systems (4bulbx2'). im flowering at 22 days right now and it seems like all the hairs are turning already!!!! ( 52 day for whiteberry) anyone? also, notice in the second pic the bigger fan leaves turned yellow, but its tips pointed up? it seemed like it stopped growing or sumthin.....but i know this strand booms big 3 weeks before picking, but im worried it wont with the hairs already turning?!?!
thanks for any help!

spraying them with any thing.

Plus it is the trichs not the hairs and the last part of flowering the buds tighten and not so much elongate.

im spraying them with some nutes, mostly organic foxfarm every other day

sometimes the neut spray will cause the hairs to change pre maturely

but my previous ones almost never turned even til the day i picked them they were maybe half MAYBE

I would not do that, spray them with clean water.

oh ok! i actually just started nute spraying this time around since i got the hotter lights

Watch the spray with hot lights the beads of water can magnify the lights.
