Ok, I've been struggling, struggling to get things "dialed in". It doesn't help that I'm new and until recently changing methods/mediums. I've settled on RDWC for now (as long as I dont need a chiller -- drawing the line there). My env is good. I get phases of smooth sailing, but not start to finish yet.
There is a plethora of information out there about using Jacks in DWC. Not so much with megacrop (yet). On more than one occasion I've had Jacks in a shopping cart and almost pulled the trigger. Honestly, if I could have got the 4# tubs on amazon, I'd probably have it. Just would like to get a solid, proven, tested baseline and tweak from there because right now it feels like playing darts while blindfolded.... Plus I like the fact the megacrop already has some of the items I'd probably have to add back in (like Si, Aminos, etc)
So as a thought experiment, I whipped up a spreadsheet and started playing around with replicating Jacks 321 formula with megacrop using what I had on hand. 321 has way more calcium and mag. Here are some approximations (grams/ml per gallon):
Some observations: It's harder to hit the targets with GLN CMP because of Nitrogen. I have Bud Candy, but it bumps K out of range trying to hit target P's.
I'm probably going to try the bottom one for a while going forward.
[edit: this is using MC 2.0 -- I have a batch of 2.1 but haven't messed with it yet]
