The early pics say more.....Yes heat was a major problem......nothing to do now but run them out,,,except,,,,,I also see some other telling facts....Like in the second set , second pic. To much P to early and running the nutrients a bit hot.
Drop the high P nute or supplement and simply run them out with the base nutrient....
Run your veg or base nutrient to week 4 of bloom and then add a small amount of a higher P bloom nutrient if you have to (you don't). I bump the P up very little at week 4 and give it a "spike" of P at week 6 and then only once....in synthetic grows.....I like Hesi nutrients my self.....but in no way do I follow their schedule.
Want something simple and effective for nutrition? Run DynaGro....water, feed, water, feed.....simple, single package and you might only want to run some silica with it, if you want to...After a cpl of good grows,,,begin to experiment with small adjustments in bloom.....Dyna foliage pro works well too!
Good luck
