Hello everybody,
This is my first post here, so greetings to y'all : )
OK, the problem:
I use organic soil, the following mix:
53% Organic potting soil
25% Perlite
10% Vermiculite
12% Worm Castings
My nutes: BioBizz, I use BioGrow, BioBloom & Alg-A-Mic.
The strain is Jack Herrer. I use RO water for irrigation (TDS < 40).
I am using clones, root them in small plastic cups, repot into 1 litre pots for a couple weeks, then into bigger pots and into bloom. Been using 1.7 gallon pots for flowering for awhile, but I think they're too small, so I'll be using 3 gallon pots exclusively now. Also need to shorten my vegetative growth phase for clones - I seem to keep them vegging for too long, so the plants become too big for their pots and for my bloom-box....
Plants are growing pretty fast, but almost from the beginning there are signs of deficiencies - paling leaf tips and also the tips of the serrated "teeth" along leaf edges. Leaf edges curling up.... the leaves are too light green in general, and other signs of defs I cannot, for the life of me, make sense of.
Pretty early on the pH starts trying to escape the earth's gravity. It goes over 7 and keeps rising. I was pH-ing my irrigation water to 6.2, then to 6.0 (using GHE pH down - nitric & phosphoric acids), with no effect. Tried flushing the big ones that are in bloom - flushed a 3 gallon pot with 9 gallons of RO water, and the pH wouldn't budge. Stayed at ~7.3. I pHed my water to below 6 for the last gallon of water to which I added a mild nutrient mix - runoff pH was not impressed.
I've spent days searching the net & reading about pH and other issues, but I'm still clueless. How do I bring the pH to reasonable levels?
Thanks,
