Little update:
I don't know what it is with megacrop. I emailed them about the new bag I bought and they basically told me if I didn't want the little balls that I should grind them up myself. Thanks a lot. Even if I could grind them up, I'd have to grind the whole batch of them and it is so hydrophilic that it would soak up all the moisture in the air before I was done I think.
Anyway, I finally got tired of more brown spots showing up in the middle of the leaves indicating Ca deficiency, while at the same time seeing tip burn signifying excess N. So adding more Megacrop was just not going to be the answer. I top dressed both plants with two table spoons of powdered dolomite lime and soaked it in with a feeding. That was on Wednesday's feeding when I saw more signs of Ca deficiency and more burned tips. I am also adding botanicare Cal/mag and backed off on the megacrop. Since then, I see no new signs of Ca deficiency and a slowing down of tip burn, and the plants seem to be responding with renewed growth and trichome development. I have read that FFOF soil often times is acidic, but I can't get a decent soil sample to do a slurry test. Both plants have such dense roots that I really can't get any soil much below the surface. So perhaps the dolomite lime with regulate the soil pH and give the plants the calcium and magnesium they seem to be needing. Anyway, the plants seem to be responding.
