Hi Farmers, I'm hoping for some help on this. I switched from coco to rockwool on this run and it's my first rockwool grow. I'm having major ph problems in the run off which my plants are suffering from. I flush once a week. My run off ppm is around 800ppm however my ph DROPS down to 4.0 or 4.7 tonight I checked after feeding for the first time after flush last night and it was down to 3.5 WTF!!!!! I always ph my flush water to 5.9 Here's my set up. My water is ph'd at 5.9 ppm 1250 2 weeks into flower, top drip system, watering 4 times a day at 3:00min each comes to 1 liter a day. My rockwool is Hugo 8X8 Grodens. Yes, I pre-soaked. My room is 77degrees, 48-50 humidity. I have no idea whats happening. My plants are still growing tall but the leaves are yellow, curling, basically dying! I see what's happening and can't fix it. They are in nutrient deficiency because my ph in the rockwool is sooooo off. How do I dial this in?
Any help please. I don't want to lose this run. I'm under 1000wt lights. If you look close at these photos you will see dried up, curling, yellow very SAD leaves.
