Wedding Cookies Pt 2 ♡

6/24 start of week 2 flowering since topping she is growing more bushier, giving flower bloom nutrient with big bloom once-twice a week, rain afternoons, spray neem at night 6/26 started noticing brown spots and yellowing fan leaves, decided to test ppm of nutes i was giving and the dose of .25 teaspoon was too low ppm i added more flower fuel (1tsp) and 1 tsp of tiger bloom to get 960 (500ppm) 6/27 next day watered plain water 0ppm and run off tested at 820ppm have been watering every morning, nutes every other day 6/29 leaves getting worse, plucked a few small ones, gave nutes 1tsp each, 960 ppm. run off tested 1250ppm which is high I figure the plant isn't absorbing those nutrients due to high ph of the water I'm giving and mixing nutes with...should i lower my ph with ph down every time I water? is the yellowing of leaves a nutrient problem? 7/1 plucked dying fan leaves, lay'd off the nutrients for last few days, will go back to nutrients once-twice a week
