I watered for the 2nd time since I posted this thread on July 31 with no nutes, and yellowing increased. The bottom to mid range is most effected, but some of the leaves closer to the top have the same problem. Is this natural and I dont have anything to worry about?

None of the actual bud spots have yellowing/browning, its just the fan leaves. Like I mentioned previously most to all fan leaves have brown tips, which I read could be nutrient defiency(maybe try leaf feeding), but yellowing of the lower to mid range is also a nutrient problem, but it seems like I over did it and burned em, so im lost on what to try.

Not seeing any more pests

Room temperature for past week 1/2 has been about 80F, and the canopy high 70's.

Also, took one of the two fans and put it at ceiling level for exhaust, has kept the room 5 degrees cooler since
