My tap water is 800 to 900 ppm. Check ur tap
What about when I go to start my flowering nutrient cycle in a few weeks, putting big bloom and tiger bloom into my tap water usually brings the pH down into the 5's. Should I use pH up to bring it back up to 6.5-7 or just run it through after nutes with no pH adjustment? I will double check the bag to make sure it doesn't show any nutrient content, but I am almost positive the only ingredients were peat moss,perlite, lime, a wetting agent, and microhizzae. None of these contain nitrogen that I know of, so if it is salt buildup/over fert it would have to be from too much lime in the pro-mix or im using too much pH up/down. So maybe all of the things I read about Pro-Mix needing 5.5-5.8 pH is outdated and I should pH at 6.5-7 and treat it as a potting soil?
I have no reason to lie about it as I am still really new and have a ton to learn, and I know the only way I can get the proper help to improve is to be honest. I actually thought it could have been caused by not feeding. These are autoflowers and they are at a really awkward week 3 preflower stage where they have recently left seedling stage, and are in the middle of a very short veg/preflower stage. I have noticed in my other grows that they start to get really P and K hungry right around week 4-5, so that's why I was planning on feeding flower nutes with my next water (tomorrow or monday).
Yep, tap water. I have never tested the ppm/ec of the water here straight from tap. I should probably take that a little more serious because if it isn't caused by something that's in the pro-mix or the pH up/down solutions, then it would almost have to be hard water right? I will have to dig up some old pictures of my past grows where I ran into what seemed to be P and K deficiencies, but it could have been lockout instead of deficiency.
