Stats:
Nirvana Bubblicious
Four, 125 Watt CFL's with home made horizontal reflectors
Pro-Mix BX medium
3 Gallon container
Flowering stage aprox 3 weeks Lights 12 on, 12 off
Nutrients, Miracle Gro Bloom Booster 10-52-10, One feeding at 800 ppm & PH 7.1.
Watering every 2-3 days at 2 gallons, bottled RO purified water with minerals added PH 7.1
2 straight H2o waterings since bloom ferts added.

Previous problems/symptoms: Early N burn evident but recovered. Initial medium already had ferts. Low PH from peat based medium some PH spotting and mottling. Have increased watering and nutrient soloutions to 7.1 PH.

I have one bean flowering for aprox 3 weeks now in Pro Mix BX. 12 on 12 off. The PH was at 6.1 last week. I began watering with RO, purified H2o with minerals adjusted to 7.0-7.2 with PH up. The PH is now 6.5 with the 2:1 media/distilled H2o saturation test. Hanna 3 way meter at .5 conv.

Question is this, is the PH up watering adjusted water enough to sustain the PH or do I need to add dolomitic lime in soloution?

Next time I will incorporate the lime into the medium prior to planting.

Thanks
