Co co coir perlite and happy frog 50/50

Yo yo, Bushdog here from Vermont. So I have been a soils grower for years. Decided to step it up a notch. At the moment I’m in the 5 th week of veg with 2 rouge kush, this hole run ? The girls just r not happy. I started straight coco pearl lite, 5.6 5.8 5.9 up to 6.2. Unhappy and I decided I must b overwatering, always removed the run off. So went from a 5 fabric pot, to a 10 gallon plastic, this where happy frog came in. Did not water for 5 days , ladies were looking better, not great. Now time to water , think I made a mistake with 2 teaspoons of fox farm tiger bloom. These gals def big enough to send into flower. Also overwatering signs , looked like a potassium or phosphorus deficiency to me. Mind u , this is all subjective, I know some basics, here to learn. Then I over thought the ph, I went 6.4 cause of the frog. Now they look exactly like where I started. Forgot to mention, a real nice cal mag problem the hole 5 weeks. Yes , I have used cal mag. So , just looking for a lot of knowledge, and trying to see if I can make these gals happy. Lol I know I can’t in my marriage, so happy gals in the tents is my only chance of any kind loving.
