I think my ph is off so I ordered some ph up and down with a ph tester kit I gave her some bloom booster 1/4 tsp per gallon of water im going to wait till I know what the problem is might just need some nitrogen.
I think you have a few things going on there first I want to start by saying ur doing a good job it’s looking good just need a lil help I think u have a mag cal Deficiency along with pH problems I would also say you have phosphorus deficiency Solution flush your medium very well with pH water get a Cal mag supplement along with a good bloom nutrient give it a week or two see how you’re looking easy on the nutrients
If you have gone this whole time without testing or knowing what your PH is at. It probably hasn't changed. And being they are in flower you want less N and more P, K
