Nute burn or deficiency?? Please Help!

I think my plants are still about 4 weeks from harvest, but all the leaves are turning yellow, curling, and dying. I was giving them about 1 gallon of water every other day, every day during 95degrees or more outside (I am in NorCal) And I was giving them about 4-5ml of TPS Bloom each watering - and yesterday I reduced that to 2ml per gallon. My buds look ok - but I am scared the death is creeping up to them!

Are you checking your ph? Your water ph might be locking out nutrients despite you putting nutes in. If not that check your soil ph or test the water runoff ph. Ph should be around 5.5-6 I think for bottle nutes
