New here (Hello!), with some questions/concerns. I have an outdoor project going in southern New England, in 5 gallon buckets. I really need the portability having everything in buckets brings, but obviously the small soil base is going to present challenges ... I think. I've grown in ground before, and typically use a lot more soil in the holes I dig, as well as the native soil being available to tap into when the root system expands beyond what I dig. Right now I'm getting some nitrogen deficiency signs, lost the bottom 2-3 sets of shade leaves, and the pairs just above that are starting to yellow. PH in a few buckets dropped to ~5.9 and I went ahead and did a flush along with dressing the top with a bit of lime (my tap is 7.0, artesian well). PH is a little high now at 6.8-7.0, but I'm thinking it will drop on its own.
But I'm thinking my soil is getting taxed. I've been using Miracle Grow, I know most growers despise the stuff, but I don't know any better, and it does work ok for its intended purpose. But I had what I believe was signs of over fertilizing (had been watching for it), green leaves with brown/almost burnt looking edges, brown spots here and there, in the plants that had the lowest PH reading. So I'm flushing to keep the salts from building up and still have nitro deficiency...... I'm still going to come out of this successful, but there's obviously things I could be doing better. In case it's relevant, I had a male I cut down 3 days ago. I took the opportunity to check the roots (was one of the low PH plants). The soil is pretty bound up and came out like brown bread from the can. The bottom (which I had a single layer of gravel to start) was just solid white roots matted together.
Seeds are Pine Warp from BCbud depot (early finisher, high yield, although probably not that high with bucket limitations)
Soil base was a custom mix:
50/50 bag garden soil and bag composted manure.
Perlite and sand for drainage
blood meal
powdered lime
Fertilizers used - Miracle grow all purpose (30-10-10), mixed as directed, 1.5 gallons distributed among 12 plants, bi weekly at first, weekly now with the leaves I'm losing to nitro def.
Also have their bloom solution (15-30-15) on hand
Specific questions:
General fertilizer advice, what should I be using instead of MG? Should I be mixing as directed/more/less/how frequently?
Should I prune off the bottom branches?
Should the nitro def signs worry me, or is this expected/unavoidable/not that big a deal?
Any pointers on how to get the most out of what I have going in the situation I'm in?
Should I fertilize in smaller doses but more frequently?
