Dry Crunchy leaves? Early orange hairs?

Okay thanks guys., I think it is the PH fluctuation, now when thinking. I've been using five gallon buckets, and sometimes the nutes sink to the bottom so not sure if my mix is staying PHd correctly. I'll go back to gallon at a time and see.

PH fluctuation , correct the ph but don't expect for a recovery , just to keep her alive to let the trichomes mature

that's can explain while ur pistils turned orange abruptly....it s not only a question of burn the plant tried to concentrate her energy to mature some flower to try be fertilized by pollen.....cause the goal of this plant is to produce seeds to survive.....to reproduce !

hi dude..... only you can know for the heat cause we dont have any info on your box on ur nutes schedule.... but if ur WW is close to the same condition that ur gelato 41 25°c can't cause this burn.....alone but if u had same or a bit higher temps or/and a light too cloose or /with a strong ventilation...... u had a harsh combo of burnt causes ....u are in the late stage in my point of view..... https://www.growweedeasy.com/wp-content/uploads/2010/06/heat-burn-appear-overnight-flowering.jpg here some pics the final problem is that during the evolution of this problem the plant loses its assimilation capacities of nutes so they burns also 😓.... it could be a slow and vicous process... hope this help for futur dude 👊
