Grow Mediums Trying Coco After Soil

[St. Tom]

You Say to not count my water ppm,so subtract from Total ppms?
If so I should up the nutrients a bit and go 0.8-1.0 EC water + nutes...right?
Those are the plants today,do not count the Tan pot one

going forwards id shoot for an ec with your starting water included of 1.0 and taking them up gradually a point here and there as they go later in veg that's my sort of ballpark I go for as they look great but they will need stronger food going forward to get them a little bit more greener

I was looking more at the tan one but yeah, I would not count your water PPM into your solution EC targets. Shoot for .8EC at that stage, and then up it as they grow. cocoforcannabis has good, conservative EC targets. I tend to overshoot them a bit, but it's generally OK. Some plants do better than others with nutes.

Basically I shoot for 0.8-0.9 only CANNA COCO A&B Total Ec,adding After that 0.4 from my tap.That Is right?
I was giving 0.8-0.7 EC totally,water included.

With what @St. Tom said,I would give 0.6-0.7 EC only by Coco nutrients,then Adding 0.4 water and we are about 1 Ec.
I Will do this slowly starting from next fertigation going up a TAD.Maybe 2 days to go full 1-1.1 EC and check Them regularly before craftinf the automated system

St. Tom is more experience than I, but I don't include water in my measurements as long as I can get it around 150-200ppm total. I'm using canna A+B as well with rhizotonic and calimagic. Will be adding greenleaf sweet candy PK booster soon as I'm in flower at this point. Good luck!
