@McDee - I didn't want to clutter the T20 thread but I saw your post about megacrop. Any ideas on what you might try next?
I've been having really good results with the Jacks 321. Pretty simple program, 3 parts to mix. I do use RO water system that I believe makes a huge difference.
I am just a couple days away from two new runs starting. One of Autos and one of Photos. Both going in coco with Jacks. Should be interesting. I can tag you if you would like? The beginning is admittedly a bit boring.
