I ran out of calmag and they don't sell it in my country. Need help, deficiency's

Epsom salts is perfect for correcting a magnesium deficiency, but you need calcium nitrate (hydro) or limestone (soil) to fix a calcium deficiency.

Thats true. I use a tsp of lime per gal of soil.

My last grow was 20 plants. My nutes for the year cost was about 15.00. A box of lime 5.00 a bag of epsom salt under 5.00 those two last a few years. 2 box's of home depot over the counter nutes about 5.00 a box but has all the trace minerals. I also add some steer compost to the soil.

I found a 1kg bag of calcium chelate (don't know what it is but they say it's for plants) and i'll be using epsom salts.

I'm switching to rdwc so hopefully i won't need much. I'm over looking this calmag stuff up all the time anyway.

Can you use epsom salt that they sell at Walgreens
