nute burn or heat stress will plants recover 5 weeks flower...pics included

I have dropped the nuted down to 600ppm from higher and raised the 400watt hps a little higher ....any thoughts on recovery.....buds look great

Looks like they have a case of ph lock. Is the inside of your pipes clean if its a dro setup. If soil to much nutes resulting in ph lock which can lead to root rot. Hows your ventilation. Good ventilation will drop heat fast.

thanx for reply its dwc setup using flora nova bloom and calmag plus in 5 gal buckts .ventilation is perfect temps never over 80 bringing in fresh air from outside always ... ph seems to be good and stable 5.7 it rises a bit daily to about 6.. I did have about 1 week the ppm went up to 1700 on .5 conversion ...lately I have been adding only ph water with a bit of calmag to get the ppm to 600 every day the ppm rises about 50 ppm the plants are drinking about 2 litres a day....

no reply I have the same issue
