Hey, Kevin..
How are those white widows coming along? That's a strain I would like to try next, along with some Ice. I didn't get a sense of how many grows you have behind you, but where would you rank white widow in terms of sensitivity to nutes, temp and other factors? A lot of seedbanks list it as a strain for "experienced growers". I think seedbank sites have a lot of marketing BS on them, too.
Looks like we are following some of the same lines. I like to keep things fairly simple too.. I might take a crack at some cloning this year and try to put some plants outside when it warms up.
I'm growing some bubblelicious and superskunk in MG Moisture Control right now. I'm going to give the Organic a shot next time; this is my second grow and I've run into early nute burn issues both time -- MG-MC is just too hot for young plants, I've concluded. As an organic chemist, I can tell you that there's no material difference between chemical and organic nutrients, but the delivery is very different -- chem nutes are "ready to go"; organics need bacterial processing for release, so they come out more gently. And the major diff between FF nutes and MG is the micronutrients -- more variety in the FF. But otherwise, they're both chemical nutes with plenty of potential for overdoing it / burning plants up. FF is acid as all-get-out too, out of the bottle -- def. has to be pH'ed up, IMO. All that said, it sounds like you have a good thing going -- watching for actual signs of NEED before adding anything, and then going low-dose.
Still LOL at the chicken rancher / short horse thing... hah!
Here's the link to my current grow, if interested:
