Hello fellas!
So yesterday, 5 days after second feeding, I checked my run-off pH and found out that it had went up to 8! I became surprised by that, so flushed the medium with plain water at pH 5.5 until the run-off went down to 6.5. Today I noticed some yellow or brown spottings on middle and lower leaves and many of them are becoming twisted to left and right, maybe because of the sudden drop in pH level and fluctuations. Now my question is: should this problem stop or can spread to the whole plant? Is there anything more I can do? I was thinking about lowering my pH to 6 next time watering. I'm growing in coco/perlite mix (50/50) and always adjust my water pH @ 6-6.4. Could this increase in my pH be due to CalMag?
Any help and answer will be greatly appreciated.
