Pretty sure.
I'm doing 130g of Jacks + 86g of CalNit. I do this in a 50Gal barrel for around 1.2EC. I do this in slightly less water to give me a stronger mix of around 1.5EC
I'll first dissolve each in a 3.5 Gal bucket until fully dissolved. I'll then add the jacks bucket to my barrel and let it mix for a while.. then add the CalNit bucket.

I was mixing via EC on my truncheon (in my previous coco circles room), but you recommended the above in a prior PM as we were finding it odd that amounts that I was adding in to achieve 1.2EC. I was previously mixing Jacks to about .7EC and then adding calnit to a 1.2EC
Below is my quoted PM to you back around March/2013. The grams I was using must not have made much sense so you advised me to revert to weighing to ensure I was hitting a .66 ratio.
I have however cleaned and confirmed my truncheon is accurate. It now is in fact reading 2.77EC in bluelabs conductivity standard solution.
This was what you suggested prior. Should I go back to measuring by EC? My truncheon is definitely ON according to the bluelab solution.

HL has directed me to some photos of a potassium lockout/issue and they look identical to what I've been experiencing.
My question.. is my mix boogered up, or is it merely uptake issues (due to the over-watering)(lack of proper charge)(or pH?) resulting in potassium lockout.

My latest photo. I think the majority are growing out of it. Been slowly pulling fans to see if I can identify if the issues remains. Hard for me to tell though.

I have been finding it difficult to keep my pH down even though my bulk res is currently sitting at 1.5EC and around 5.4pH. My pulse res however climbs up and is sitting at 6.5 now. I've found it at 6.8 before. I've sometimes been doing just a splash of down into my pulse res to correct to 6.0, but it quickly goes back up after a few cycles which is what I expected as I can't alter my pulse res pH itself much, and my lower bulk res pH doesnt seem to be pulling it down over time.
I think things are improving, but I'm all ears guys if you've got any suggestions.
I think that the small amount left in the bottom does eventually cause problems over time. I was doing the same thing as you, just leaving the small amount of solution in the bottom and refilling the res. This bugged me, so I got a pump that pumps down to a half inch then automatically turns off. Then I fill the res back up 1/4-1/2 way with tap water and drain it out, then I fill with RO or filtered water.Thanks for the replies.
To be clear my pH of 6.5 or so in the pulse res isnt what I am getting after mixing up my Jacks+CalNit in RO. It actually nets me a pH of around 5.2-5.4. This might climb on its own a bit, but my bulk res has been consistently testing in the low to mid 5's while my pulse res is always 6.4ish.
It must be only after the pulse/feed cycles that I'm seeing the rise in pH. I initially thought this was due to too low EC so I started pumping into my bulk res at 1.5 as opposed to the 1.2. I am running sealed/co2.
I will add that I'm mixing in my RO barrel. I mix as I described in my previous post and pump it all to my bulk res with a large pump.. now, this does leave me with a few (1-2 gallons maybe?) in the bottom of my 55gal drum that the pump can't pick up off of the bottom. I ignore this amount and flip a switch to refill back with RO. You don't think this could be giving me problems do you? My RO refills never register on my truncheon so it's got to be pretty low ppm.
Tomorrow I think I'm going to try to drain the system completely and re-dose with a fresh batch made in a clean/empty container measured by EC as opposed to weight without doing the bucket concentrates.
I'll keep up with the weekly updates sink or swim. Hoping that while despite the issues I'll still bring this to a successful harvest as opposed to Dave's unfortunate death mid-bloom.
Only time will tell...
PS - despite my less then flawless plants I really am loving how boring this shit is. Cant wait to go turface. I've got a bit of outdoor space so I better get building my slide.
aren't both you guys using longer tailpieces than the 6" ones i use?
