Plants in coco need to be fed daily with the optimal situation being a smaller pot say 2-3 gallons recieving a few feeds per light cycle.
When you let you plants dry out the salts are concentrating as they are coming out of solution with the h2o. Then when you run fresh solution, all those salts are being picked up in the run off and your PPM shoots up. The roots are sitting in that salt, and water is being dragged out of the plant by a concentration discrepancy and you leaf tips are where that water is coming from. Also you get a situation now where the plant can’t take in nutes because the water is flowing OUT of the plant not in!
Not sure what your ratios are but your ppm is good..make sure to read H3AD’s sticky in the coco forum, good stuff.
Run nutrient solution EVERYDAY!! You need to provide oxygen and total coco saturation DAILY! Always run nutes in coco! The ONLY time to run regular water is in flush!
Get in the mindset of coco is hydro...
Start running fresh nute solution daily till run off is pretty much coming out what’s going in and I think you’ll be fine.
