Hi Gandalf, are you growing in coco? If so, do not let it dry out. It will cause your root zone ppms to go crazy which will turn into lockout/deficiency/or even burn. From my experience with coco, I never let more than a few grains on the top go dry. Coco is to be treated as a hydro system. Feed lower ppms at a more frequent intervals. Feed to runoff as well. I would recommend flushing your plants with half nutes. Check the initial ppm runoff to see whats going on. Ideally that ppm should be close to what your putting in plus or minus 100. If its significantly higher, keep flushing until you bring it down to range. Also, take a coco sample from deep in the root zone and do a slurry test. Take 1 part coco and mix with 1.5 part 0 ppm RO water and mix thoroughly. Set aside for 2 hours and mix it up again and check the ph. Make sure your in the 5.8 to 6.1 range better 5.9 to 6.0 to be perfect for coco.
This was my biggest "A-HA" in improving my grows. Lastly, your feeding ppms seem awfully low as well, most autos in flowering if fed once a day should get 500-800 ppm. I see signs of N, P, CA, MG deficiencies which will really hurt bud development especially resin and could lead to hermie as well. If it were me, I would flush the hell out of the coco until the rootz one ph reads 5.9 to 6.0 and ppms running off at 700ish ppm. Just trying to pass along some experience, not trying to step on toes. Best of luck finishing her out. Cheers!
