Hi every body I need some advice about my PH levels .................................................I have a ph level of around 7 from the tap and i've been using PH down to bring it down to 5.8
i'm using rockwool slabs in a flood and drain system and i've checked the runoff ph of them and it's around 4.8............now should i raise my ph in my rez gradually to bring the ph of the slabs up to 5.8
I've been noticing what i think is a calcium defeciency and just by what I've been reading .............this is from (mynamestitch) THANKS VERY MUCH
"Calcium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0- 5.3
Calcium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.4-5.8 (Wouldnt recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Calcium Deficiency."
does anyoneelse think that i should begin raising my ph until the slab runoff is between 5.4-5.8 It might mean that my nutrient solution is as high as 6.5 or 7 .............which is right where the tap is right now!!!!
I might get away with not adjusting my tap water at all to get it up to the 5.4 to 5.8 range
any thoughts???????????????????????????
