going onto 4 weeks now. I watered with nutes and the runnoff is 2956ppm. I have no idea what this figure does for me. I remember seeing some onformation and charts but now I cant find them.

Runoff PPM should be ~1,000, though it is common for it to be very high with new soil. 2956 isn’t too surprising if in new soil.

I’m assuming this is a soil grow?? Regardless 1000 PPMs is the optimum TDS with 1200-1600 being the upper threshold. With the run numbers you have I would water feed only to get this down. Give us some more grow info, medium, nutrients you’re using and your feeding/watering habits
