Nute or Light Burned Trichomes?

This is Afghani BullRider Kush

Little Sugar leaves taken from top colas

3 Step AN used throughout Veg/Flower

So far 1 Month 1 Week veg, 2 Month Flower on Sep 1

big bud was used last week (Never used before) used twice since, still 1-3 weeks till harvest (Buds now just forming rapidly)

Trichomes seem to be degraded, degrading, nutrient burned, or light burned.

Temps are usually 75-81F 25-55% RH During Day, 65-75F 20-60% RH During Night. This was with the light hanging from its side with some heavy watt CFLs on top of plant (Wasn't enough room to hang HID from top) for the first 2 1/2 months.

This changed 1 week ago now 65-75F 35-55% RH During Day, 65-75F 45-60% RH Duriung Night, Now light is hanging from above with very limited space. 7-9" from light, 3-4 from glass of air cooled hood.

Plant has 4 main colas each tied to lean slighty to the side of each direction and shifted every few days, anyway let me know what you thinik.

Seems too cool to have heat stress. Do the rest of the plants look fine? Could be a genetic thing?

they look good to me man.

Well if you look close you can see some are not cloudy but a tinge yellow and some random red/amberish ones popping up but its mainly still hairs you can see budings forming underneath them but still 2-3 weeks at least I believe

One other question is how long should I continue to use Big Bud by looking at this Trichomes?

Also to answer the first guys question the rest of the plant is fine just minor burnt tips
