do you find that the P is too high with dyna gro bloom? Thinking of using a bit of epsom salt and DG bloom in flower for my hpa system. Numbers seem a bit off though

30 days from flip.
Second runoff reading:
350ppm / 0.7 EC in, 500ppm / 1.0 EC out.
pH 6.2 in, pH 6.2 out.
- Both are stable and within range. I'll try to keep output under 1.0 EC out and I'll probably lower to 0.65 EC input and call it a day all the way through flower. They seem stable somewhere around here.
Cheers!
Hey there Wastei, looking awesome. Have a quick question about potassium silicate in my hpa system.
I believe that you ran 30-50ppm of PS in your aero system correct?
I’m running agsil16h and being told to run 16gs per 100gallons for aero. It puts my ph right at 5.8 using Jack’s 321 with RO water but it’s only 12-15ppms. If I go to 30ppm I do need to use ph down which isn’t the end of the world but wanted your feedback (please). Do I run 300ppm or use as directed?

I'm helping my friend out ordering mineral salts from a local distributor of Yara.
I decided to make a copy of Jacks 5-12-26 since it's simple and effective and not accessible in the EU.
Jacks 5-12-26 copy:
3330g Magnesium Sulfate
1150g MKP
480g Potassium Nitrate
250g Rexolin APN
~ 5kg
/////////////////////////
16.65kg Magnesium Sulfate
5.75kg MKP
2.4kg Potassium Nitrate
1.25kg Trace mix/Rexolin APN
Total: 26.05kg
Jacks 5-12-26
Jacks 5-12-26 copy
The different ppm values corresponds to the different batches and quality of the different mineral salts. Manganese is higher in the copy but with dilution I think it's a better concentration being slightly higher. All the numbers are from ~5g per gallons of either mix(they're more or less identical).
You could modify this formula and remove potassium nitrate to create a Copy of Masterblend 0-12-24. If you add back the potassium with potassium chloride you have instead created Jacks 0-12-26 formula. I guess they needed to change it slightly to not be a straight copy of Masterblend.
I hope this info helps somebody out, especially someone trying to source nutrients and minerals salts in the EU and wants to stay under the radar and at the same time use the best mineral salts available.
Cheers!
