Ah, dolomite. This might be the reason for your deficiency. It acts as a Ph buffer waaaaaaaaaaybefore it breaks down to make any magnesium available to the plant. Replace Dolly with a 50/50 mix of gypsum and crushed oyster shell. Another issue is how it is nailing your Ph really high. Dolomite lime removes the olant's capability to control Ph. Nutrient absorption changes per nute as Ph and temps change. I have a feeling your narrow Ph range coupled with lower temps are also affecting uptake. Epsom salts work very well for may deficiency, half tespoon per gallon water should do the trick every time. But in my OPINION top dressing worm castings is the best emergency treatment for most non bug issues.
I'm really wishing I had never bought any. It was just so cheap on that Hydro store shelf when I first got into Organics, box lasts forever too..
Well I went ahead and got some epsom salt last night and gave them a small watering (they already got watered yesterday morning) at a ratio of a tea spoon per gallon. I also used it to give them a foliar. Somewhere suggested I focus on getting the underside of the leaves more so than anything, so I did.
I also went through my worm bin last night and there's no way I'd have enough compost to top dress even one plant. I need to buy more worms instead I've been procrastinating for a month.
Sigh. If the epsom salts don't work I may not be able to get any vermicompost / castings before I get paid again. So hopefully it does!!
How long does dolomite take to break down? I've let my soil mix mature for almost two months now, it's like 50+ days old now. I'm not afraid to give all of my plants some epsom salt but I'd rather avoid that if possible.
Maybe make a very light epsom salt "tea" to compensate until the dolo works and water that mix into my maturing soil? My Yunnan landrace that's a week younger than these 3 gals I've been talking about acts like it has nothing wrong with it even though it's in the same soil, less mg intake?
You are right, it is a great idea for a thread, call it 'dangerous or useless organic amendments' or something like that. There was one like that on a different forum which happens to be exactly where I got all my info on dolomite lime from. Coot was very good at explaining it all. That particular overdosed crop was taken to finish but just barely. Got some bud is all I can say. It was pretty severe though, one of my first ever runs so when I was told to buffer my soil I just dumped a bag of the stuff in and barely mixed properly lol... bro it was BAD.
