I've been growing organic in soil for years with great success and the only time I adjust the ph is when I flush them with water adjusted to 6.0 for the last 2 weeks. During bloom I use either Bio Canna or Bio Bizz nutes or else some homemade guano teas. I always thought organic nutes self regulated themselves,ph wise, maybe if somebody knows better then they can let me know.
I thought a ph meter couldn't measure organic nutes with good accuracy, so instead of adding lots of ph up or down I just fed my plants the nutrient mix without adjusting it and my yields from it are nearly on par with my nft system, where the ph is constantly monitored.
Great chart. Can someone give me an idea on how I can lower my ph in soil? My ph is reading 8, so I need a way to lower this. First it was too low..5.5.. so I added bone meal and baking soda but my plants weren't improving, so I just started over and transplanted into new soil (miracle grow organic). They look much better, but now it is 8. I've heard lemon juice or vinegar in water works, but it doesn't last long. Is there anything I can top-dress the soil with?
i see every one has Q's bu tthey get little answers? Well I have one as well th ph of my guano tea.( One tbs pr gal-guano2tbsewc5ml liquid karma and onetbs mollasses.)
is very low ph up does not work in moderate amounts to adjust my ph of the tea. And the soil becomes acidic (foxfarm happyfrog soil is used.) Should i used bone meal? in the soil or the tea? how much? or should i add one tbs of lime per gallon of soil when i mix soil and perilite? or Both? The chart looks nice but how we apply it is most important. Also my plants grow healthy and have quality smoke with ph of 4.5-5. All seix varieties.
the chart refers to your water with nutes in it ( the ph of your soil is or should be from 6.5 to 7.0) soil nutes should be 6.5 hydro 5.8 . yes you can use ph up and ph down at same time what ever it can do to plants ph to high or to low will be worse PH stands for possable hydrogen or IMU to much H = alkaline to little = acidic hope this helps
EVERYBODY GROW EVERWHERE :harvest:
BG - thanks for the adjustment advice for the ph meter. I have been using the garbage can and was not aware of the hammer trick. After 4 ph pens 2 different brands I am done with those shitty things. The drops work awesome!!! I rarely use the drops or ph meter anymore as I have found my water source is very ph stable and consistently tests to about 8.0-8.1 which I have determined the formula on how to adjust when feeding and use the same formula every time......works like a charm (1 year + now no probs). Also another trick is when you empty your dehumidifier water use it for watering plants the water will always ph at 5.9-6.0 and is pure as distilled water with no contaminants.
All this PH talk and I am almost getting confused. I have been PH'ing my nutrients, plants in soil (pro-mix), always to 6.2 throughout flowering. Should I be doing 6.5 through the entire flowering period? I have know some guys here to lower their ph to 5.8 the last 3 weeks of flowering, is this nonsense?
