Personally, I’ve ordered from Royal Queen Seeds, The Attitude seedbank, and also North Atlantic Seed co. I can attest to the customer service of RQS. Three of their beans sprouted but quickly died off. I emailed them a few pictures, explained what was going on, and they sent me three new beans. Top notch customer service

I thought it could be a mag deficiency, so I’ve been adding epsom salt to the water. The synthetic nutrients have calcium in them, just not much magnesium. I have a feeling that I could be ph related

Should I just use plain water then to help flush the salts?

I haven’t checked the ph of the soil. From my understanding, growing in soil, the ph tends to buffer itself? Idk if that’s accurate, but if not, that could be the issue
