twenty20 Mañ'O'Green does Twenty20 Mendocino Knows Candy / MSG / Autowreck

I am not giving up. I will figure it out but I must admit that I am frustrated at the moment. I hate it when my tools and knowledge limits what I want to do.

Hang in there @Mañ'O'Green Your heavy lifting is appreciated.

I assume "the addition of substances that interact heavily with plants wants to be avoided" includes N

if you get that feeling imagine how we mortals feel always a pleasure to watch your adventures

OMG I just found a math error in my spreadsheet

I was only calculating half of the Potassium strength of reality. The 5 grams I added to yesterdays formula took me over the redline and as we can see Too much K locks out the Ca & Mg. Just what I am seeing. There is still too much N as the dark green in all plants and little bit of clawing on the Autowreck in the back is showing.

Maybe I should go over all of my math while I am on this Tolerance Break

I am looking into using calcium sulfate dihydrate (gypsum). I was always under the impression that this was not soluble in water. I found an article that states that it is soluble up to 550 PPM before it begins to drop out of solution. Since I only need to add 100 - 150 PPM this should work for me.

Dissolve the gypsum first into sulfuric acid. Be careful as the reaction can be quite direct!!

1. Use a large beaker or other glas container (min 1Liter / 1 quart)
2. Take 1gram of gypsum and put against one side of the wall of the glas container.
3. ***PUT ON SOME SAFETY GLASSES***
4. Use a dropper and carefully drop two or three drops of sulfuric acid in the glas container. Not directly on top of the calcium, but on the opposite side... Now swirl the container around. The reaction will take place immediately and the calcium will start to foam, be careful for your eyes as the foamy bubbles are a mixture of a base and an acid.
5. repeat step 4 until only a clear liquid remains... (maybe 4 or 5 times, depending if you used two or three drops)
6. Put the container on a kitchen scale and zero it. Add 1000gr of demineralized water (actually 999gr)

This should give you a 1L bottle with about 294ppm worth of calcium which is directly absorbable by the plants

Ignore the above answer as for this price you don't have to play crazy lab assistant

You do know you are talking to a pyrotecnician. I know how to make acids and bases go boom
