I'm a newbie and I have been watering all wrong. I do let the plant dry out before I water but I have not been flushing the old nutes out every time I water. I have been just watering until the top and middle is wet I guess and not letting it drain to waste. I found this out because my leaves started curling and drying out and I finally broke down and bought a good ppm and ph pen and I found out the my ppm was off the chart. So I know now what I'm doing wrong but could someone please tell me how to fix it. How many times do I need to flush it out? what should the ppm read when I'm where I need to be. I'm in pro-mix and feeding with jacks classic for veg. The blue stuff. The plant is about 8 weeks in veg. If you do a run off with pro mix, the pro mix reads 300 and something by itself. Should my ppm combined with the 300 be at about 1000 or around 700 and should I just water with water only for a week or should I start again at where I need to be? I sure hope that makes sense and someone can help. Thank you very much.
