What type of medium;coco What brand and type of soil? biobizz coco coir Indoors or outdoors? indoors What strain? Nl auto How old are the plants? ~16 days What is your watering frequency and source of water? every 3-5 days What, how much and when was it fed? NPK? Hesi tnt complex What is the medium/runoff pH and PPM if in hydro? So this where the problem lies. Yesterday i checked cocos pH it was 7.3, so it was about time to feed so I feeded with tnt complex about 350ppm at 5,5pH, I checked it today and runnof is 7,3 and checked from pot is 7,8 so I don't know how to stabilize ph that my plants would get all their needed nutes, any help pls? I really don't know what to do now so any help would be really great.
Just run a shitload of water through them. Add 5ml per gallon calmg and 1ml per gallon of your base nutrients to the water and run 3x's the volume of the container; 1g container gets 3g water/feed. Coco is easy to correct, just don't run straight water and don't worry about running ph or even attempt to measure the ph of the actual medium. Check ph going in and the EC going in, and the EC coming out if you're unsure of how much you should be feeding.
