I will switch to RO water and get the cal mag and B-1 will I need anything else? Thank you so much for taking the time to help me. I don't really consider myself stupid but sometimes this stuff gets so overwhelming it makes you fell that way as well as having a very steep learning curve. LOL
Yeah hydro can be confusing at first but once you got it down, you want to push limits. At least that is how I felt.

Anyway, I hope you haven't bought that tds meter yet. If you are willing to pay 129 for just a tds meter, you might as well look into getting an Extech EC500. It's a waterproof EC/Ph/TDS with temp and salinity. You can get one online for 139+tax and S+H. I mention this one because it's the one I use. Ultimately it's up to you but once you know EC and how it affects plant growth, you might want it.

I noticed you don't have any grow nutrients. Your nutes have enough P and K but not enough N for vegging. Yes, you will have to modify your recipe to get the ppm's right.

This is how I divide my recipe for ppm's: (Using GH 3-part for example)
Measurements are per liter

Week 1 Veg
4ml Grow
2ml Micro
1ml Bloom
2ml Gro Sup
0ml Flwr Sup

Week 2 Veg
5ml Grow
3ml Micro
2ml Bloom
3ml Gro Sup
0ml Flwr Sup

Week 3 Veg
6 ml Grow
4ml Micro
3ml Bloom
4 Gro Sup
0ml Flwr Sup

Week 4 Flwr
2ml Grow
4ml Micro
6ml Bloom
0ml Gro Sup
4ml Flwr Sup

Week 7 Flwr
1ml Grow
3ml Micro
10ml Bloom
0ml Gro Sup
7ml Flwr Sup


Grow, Micro and Bloom are thought of as N-P-K. Then you have your Grow and Bloom Supplements. And I give recommended doses of Micro Nutes, CalMag and B1.

Just to give you an idea of how you should divide up your nutes to have a stable recipe....

Hope this helps....
