Pro mix starts at around 5.5 - 5.9. I've been adding lime in an effort to get around the pH lockout I tend to hit in late flower. My thought is, start higher, water lower. Test regularly and adjust as needed/if needed.Doesn't promix already come buffered with lime? if your adding more when you water it raises the ph of the soil.
Stop adding it :P
PH down till your root zone ph comes out closer to target.
Unless I'm just flat out wrong lol.Pro mix starts at around 5.5 - 5.9. I've been adding lime in an effort to get around the pH lockout I tend to hit in late flower. My thought is, start higher, water lower. Test regularly and adjust as needed/if needed.
6.5 is good! With 6.0 - 6.1 leech... It was my target. Lol 6.8 is surprising is all...
At any point will that amount of lime bring the pH of the media above 7 if I'm consistent in watering in at the appropriate pH.
Gotta roll with it, it is an experiment after all, no point in stopping now. If I fail the lime goes away or gets cut in half...

Your right... Try cutting the lime in half.Unless I'm just flat out wrong lol.
Roger that. Less lime.Your right... Try cutting the lime in half.
Ppl need to remember that we need to build our soil to match the nutrients and source water we use.
Straight peat is what I am familiar with but iron sulfate will work... Don't ask me the dose to use though I have no clueTop dressing with unaltered pro mix? Good idea to lower the pH in the cups testing higher?
You may have a disaster brewing!? I did the same thing, put Dolomite in my pro mix and the pH was through the roof and I had trouble the whole grow with various lockouts, I never did get it below 7.2 the whole growAs some of you may know, I've been teaching myself about media pH and alkaline buffering. I recently started mixing 2 tblsp dolomitic lime per gallon of promix hp. w/ 1 gallon of perlite to every 3 gallons of promix/lime.
I start prepping the media two weeks in advance to allow the lime to activate. Before planting the cups are flushed down to 0.8 EC left to dry and then fed at pH 5.9/EC 1.2. after feeding the media is testing at a pH of 6.5, leech water pH 6.1 EC 1.0...
Mostly I have happy plants but the clone cups are testing at around 6.8... giving me problems every couple days. I think they got a higher concentration of lime... I'm going to top dress those cups with a little straight pro mix at the next watering, hopefully that brings the pH in line with the other plants. I plan to continue watering in at 5.9 as long as everything stays consistent.
My question; Can anyone provide a little insight on what I've done here and whether or not my chosen course is the best one?
Thanks!

Well, they are not in final pots yet... The flowering plant is happy. Shes in a similar mix... Its just the five cups, cbd strain out of 10 plants at various stages.You may have a disaster!?

Also I would have trouble believing that it comes out of the bael at 5.5 their website says 6.2Well, they are not in final pots yet... The flowering plant is happy. Shes in a similar mix... Its just the five cups, cbd strain out of 10 plants at various stages.
I dont think I overdid it by that much...
