The plants were re-potted about three weeks ago with a supposedly all-in-one, high end organic soil I picked up at my local garden supply. The package stated that it had all essential nutrients etc. including B1 and that I wouldn't need to fertilize for at least three weeks after planting. Other than that, I have given the plants a very diluted foliar spray that has B1 and Iron in it. I've been monitoring the PH and itis out of whack at 7 but I'm not sure how to correct it without risking damage. I do have some Fox Farm on the way I think it's called Grow Big? which I plan on using once it arrives. I've also dressed the top layer of soil with diatomaceous earth to ward of any soil crawlies.
