You ain't a kiddin' Middler, it sure is. I would rather deal with leaf spot than bud rot though myself, be thankful that nasty spore has not crept into your garden so far.
Plants look beautiful man! Much farther a long than mine, but mine were put out late and I still have yet to put out several more. Hoping my plan will work out this year with a late grow.
I am using the exact same thing, sea grow bloom. I also have some Earth Juice Seablast Bloom I feed with as well for a side by side to determine which I like better for next year. I like sea grows ingredients better myself though.
I also use growmore liquid Kelp Extract, Madagascan bat guano, epsom salts, calmag, earth juice catalyst, azos, mykos, azomite and real growers recharge as well. Do you do much foilar feeding with the seagrow? I do in early flower and it seems to do great.
How much you mixing per gallon per feeding? I'm assuming the minimum since you feed every 6 to 7 days?
