Started an ilgm amnesia haze auto in tap water (ppm170) with added nutrients (4-3-6). Grew fabulously, now 3ish weeks, no problems. Added ilgm blueberry auto a week or 2 later, had issues (brown spotting on lowest true leaves) due to what I thought was switching to distilled water (tap is ph 9.5!) and resulting calcium deficiency. I ordered cal mag and added it, but symptoms got worse and started on the higher leaves too. Switched back to tap 2 days ago, continued getting worse. Added cal mag again today, but my little girl is looking crunchy and curling under, and I’m worried maybe its not a calcium issue. My older plant is starting to get brown spots on lower leaves now too. Both plants are looking pretty droopy after adding the cal mag today. Thanks in advance for any help.
