Hey guys so I'm in Canada so I'm allowed 4 plants...this is my 4th grow now and every single time my white hair turn dark ealry ..like by week 3..every time with 3 different stains...now I'm half way thru week 3 flower and again white hairs coming out brown, orange looking kinda burnt.its happening on a few sites on each of the 4 plants ..some at the top some in the middle and some bud sites on the bottom of the plant..I asked so many ppl and I still havnt figured out why..
My temps at 80 with light on but still around 78 with lights off because I turn my ac off when lights go off..co2 at 1500, humidity at 60..spiderfarm 4000 light 30 inches away and around 650 ppfd
I have 2 fans one on each side blowing low speed and Rotating...one small fan on top blowing the co2 in a sealed tent
They seem healthy otherwise drink about 2L each every second day and I'm doing a feed feed water schedule. Current feeding at 1000ppm ph 6.0-6.4
I jus defoliated 2 days ago
Any ideas on what going on with the hairs would b appreciated thank you






My lights on temps are 80 because my ac is on but to save power and also so my neighbors don't wonder why the ac is on in fall I turn the ac off during lights off but the temps stay around 78..how big of a problem is that?
Also more and more pistils are coming out brown and burnt looking
