Help: Leaves Curling Up & Brown Spots

I have already flush it with ph at 6.5,
Today I fed them with 0,5ml of bio grown, 1ml of top max and 3ml of bio bloom that contain potassium ecc so want to see these days how things go
 
Thanks everyone for the help, I still thinking that are heat stress! But I will buy bud candy and rhino skin and test it!

If you check the soil water coming out of the bottom you ph might be high. You can also take vitamin C put in hot water blend it add to watering plant will take the stress out of the plant, guy called the farmer the company hired to water our plants mess ours up his water testing equipment messed up, so I mixed Vitamin C in and plants went Back to color and finished budding. PH in water coming out was high
