dolomite lime or epsome salt?

[HansBud]

hey everyone so I have a pretty bad mag deficiency going on and I believe its from acidic soil (6.4)ph the pictures posted are from last week but has progressed up to the middle of the plant on just the big solar leaves. I've watered twice with half gallon of water and usual nutes with calmag added and phd the water to 7 hoping it would help bring the soils ph up but no success. I'm wondering since dolomite lime is a natural ph up and has a good source of mag but is slower absorption compared to Epsom salt which is faster absorption I'm just not sure how espom does with ph would one be better than the other? Or neither? And just flush and re feed?
Temps 68-88f(its been hella hot here past week)
soil happy frog with perlite
4 300watt blurples
nutes- general organics go box,advanced nutrients b-52/bud candy
fox farms tiger bloom once a week

mix one tablespoon epsom salt in a gallon of water and soil drench and foliar spray. works fast. GL

can I foliar spray while flowering? And water and foliar feed with just Epsom salt?

You can use epsom salts to fix the deficiency now, might be a bit too late for dolomitic lime for pH buffering, not too late for granular lime however, if you do use granular do NOT use too much as it contains a crap load of calcium and can break down in weeks, too much will worsen your mag problem. With a decent amount (tablespoon p/gallon) it will help up the pH a bit but you will still need epsom for mag. Next time, cook the soil with dolomitic lime and it will help prevent future pH swings while eradicating cal/mag/pH issues in the future.

ill giver a shot and see what happens I do however have ph up can I just ph my next water/feeding to like 8.0 to raise the soil ph and just add a little epsom? Or is that no beuno? I was dumb and didn't ph my water for the first 4 weeks of their life and I believe that's what's causing my issue now

With synthetic ferts? Yeah i would pH to 6.5-6.7 and water with run-off everytime to help prevent low pH build up, You can also try leeching with 6.5 in basically same thing as flushing but without the excessive h20

I use just the fox farms once a week I believe that's the only synthetic I have, the rest is organic but even that bring my ph down to 6.2-6.4 which I didn't know cause they say no need to ph water once added, and I will now do one water a week with light nutes and make sure I get run off cause I never water till I see run off

You said you added cal-mag when you've seen the problem right? If no more mag deficiencies show then you've probably already fixed the problem, still an epsom salt watering wont hurt.
