I have my seedlings which are 3 weeks and 5 days old and in starting to notice that the tip of the bottom leaves are kind of being burned. I have planted them in coco 2 days ago and started neuts 2 days ago as well. my drainage water from the coco is at 2200ppm and 6.5ph. is this normal or i didnt flush it good. I'm feeding my plants at 370 ppm and 5.8ph. should I stop neuts and just drain it with plain ph water.
The run-off was 2200 ppm after you transplanted? Run-off should be within 10-20% or so of what goes in. If you watered them at 370 ppm and it came out 2200, that should the main problem.
