I have a constant magnesium problem that I can't figure out to save my life. Every time I switch to flower I have a magnesium problem that sets in almost right away and I have to battle it the whole rest of the cycle. I have used multiple mixes and every time it happens. I've used Lc's mix and dank Frank's mix and Coots. Same problem in all three mixes. I just need guidance on what I'm doing wrong and how I can fix it.
Currently im using lc's base mix #1 with 1 cup of dolomite per cubic foot.
Peruvian seabird guano 2/3 cup 12-11-2
Indonesian guano 2/3 cup 0-7-0
Worm castings 1 cup
Maxicrop 1-0-17 1tspn per gallon
Added to 5 gallons of dechlorinated water and brewed for 24 hrs. Used at every watering in flower
Even with the dolomite lime and worm castings I'm not getting enough mag. I even switched from wiggle worm castings to high quality castings I get at build a soil because I read that if you use high quality castings you should never have a problem with magnesium. That didn't help either. There have been cycles where I've added 1/2 a tspn of Epsom salt per gallon every watering and still didn't fix the problem. I've even recently been using genral organics calmag every other watering and it has helped some but hasn't fully fixed the problem. I thought about adding it every watering but I didn't want to make things worse with the extra calcium when I'm only having a magnesium issue. The only time I really see improvement is when I use Epsom salt as a foliar. That makes me believe that the soil is either deficient or for whatever reason the plants can't get the magnesium from the soil because something else is locking it out ? I am at a loss and don't know what to do to fix the issue. I am planning on dollar feeding one time a week with Epsom salt on my next cycle if I have to. Any help would be very much appreciated. I know the problem is in the soil and I just need help fixing it.
