[*BUDS]

its not heat stress. I think it might be too much nutes

Yes i agree. Get back to basics and use just vega then flores and finish the last 2 weeks with boost only.
I use terra and this works great , no burn, no yellow leaves before the last 2 weeks, big healthy heavy buds. Also raise the light as well to reduce intensity on stressed plants.
