Seedsman Purple Haze Auto & Lemon Auto

Lemon auto plant is having some issues. Purple Haze Auto and other Lemon Auto are doing fine with zero issues. I've noticed that the Purple plant is now starting it's preflower phase, just a week a or after the lemons🍋 and that calyxes are slight pink to a purple! I've also realized I've been watering with Reverse Osmosis but not doing slurry tests as previous cultivars haven't needed to have PH up or down, I have almost 5 acidic water with EC 20, PPM 15. I was feeding 2ml cal/mg before I had toxic symptoms on all plants except bagseed. Anyways, my ph is too high and my soil reader is old at and saying 6...i feel like this plant has both Geranium Rust Fungus and mg deficiency. I will PH my water to 7 and add 2mL cal/mag per Gal and let sit 24hrs before watering. Bagseed plant, so strange but has the center of my attention. This has to be a landrace strain from back in the days when brick weed and schwagg was still hip(I still love brick weed myself!) as it isn't expressing alot of hybrid vigor. Branching and frame of this plant is very Indica and I see no definitive example of plants true sex...this being almost 60 days into this grow. That and the sex parts aren't showing balls or spikes either, just crab like growths, almost like a premature leafset at the middle of a axiom but smaller. Weird. I removed these plants stand which gave an extra 12" off the ground, lowered lights 4", bam..within 2 hours all plants were "praying" like to say "thank you for moving me away from that hot ass light, shit!" Lol Could be light burn for the one lemon auto. Will keep you updated.
