AMAZON BLOOM IS KEY! I just harvested my girls four days ago: two L.A con, one NYC diesel, one Master P. OG. All 4 plants were vegged and flowered in Amazon Bloom soil with mixed perlite (30%). The L.A. Con were clones off my previous lady grown in FoxFarm OF her whole life with some deficiencies in last 4 weeks. I swear my plants had NO problems in this Amazon Bloom soil, they packed on weight very rapidly, but didn't make new growth until 2.5 weeks before harvest? The yellowing of leaves came naturally around last 10-14days.
I used full spectrum botanicare nutrients at 25%-50% the whole grow and again, no clawing, no added dolomite, and when I did pH check on runoff 7 days before harvest the pH was flux between 6.45-6.55. I am happier with Amazon Bloom when compared to Happy Frog or Ocean Forest. Roots Organics, I have had bad experience, whereas my boy grows pretty short and fat ladies with Roots Organics.
