TL;DR: My tapwater is really hard. I use pH down on it now. So, I am wondering, is this excess of calcium (or something else) and/or causing nutrient lockout? Or is this a calcium deficiency? Is it a phosphorous deficiency since it was really looking fairly decent until flowering began? Is it something else entirely?
My plan is to use reverse osmosis water from the store now (sigh…) and add organic calmag and organic pH down. Please let me know if that is a terrible solution!
Humidity is 40-60%, but usually 40%, sometimes lower. Temp is almost always 78-84F, usually 81. Organic soil (Promix for herbs with “3 months feed” and myco and perlite, extra perlite, extra myco, vermiculite, worm castings).
I was using black molasses at first but realized that is really for flowering stage. I might start using that again, but I don’t know if that’s dangerous at the moment while I have no idea what’s happening.
Mars Hyrdo 150w TS1000 about 14" from canopy, did some very artless LST (feel free to advise me there too).
I also had some pollen sacs develop, and I removed those. I’m keeping really close watch for more.
This is my first grow, and I thought it was doing okay. It’s still doing okay, but obviously something is seriously wrong, if it’s developing sacs, has the chlorosis and necrosis, etc.
Photo spam below. I have included many photos of the WW, but I have also included for reference two AK-47 seedlings to see if anyone can spot signs of the same issues and thereby figure it out. I also have a photo of a basil plant.
