I have had a lot of PH lockout since I started in September. I have a list of about 10 DIFFERENT things I've done to abuse the plants, so its not even worth going there (soil, light, air, water? where do you want to start?). I grew some pretty crappy weed, but now I know what these plants can take and its quite impressive.
The water here is 7.8ph and 800ish ppm, its hard water with a lot of cal/mag.
I have started to use RO water (20ppm) and then just put about 1/3 or 1/4 of tap water (which run through an anti-scale whole house filter as well), enough to get the PPM to 75-150ppm.
I use living soil and top dress the glandular amendments. In the water, in the past, I've added epson salt, cal/mag, molasses, silica, mycos and phdown. Now I'm just recovering from nute lockout on my current grows that's in week 6 of flowering (from adding all that crap AND nutes AFTER lockout
lmao). I have 10 plants coming out of veg stage soon...going treat these gals like queens! I promise ill try.
My question is because I am adding in this 100ppm of cal/mag from tap water, should I still add the 60ppm of
general hydroponics CAL/mag with every watering? Its better to add the tap water because of the buffering qualities, eh? Also, I'm afraid I'm killing bennies that cal/mag liquid nute, but I have it and ill use it if I need it.
