Thanks for your help, John. I'll keep you posted on my progress.

John, I later realized that was what you were referring to but it raised a whole new question for me about ph up and potassium bicarbonate. Now I'm back where I started and would love some input on acceptable sodium levels. Thanks for replying.

Does anyone think 16 ppm of sodium in my tap water could be problematic?

Thanks, Judge. That's the helpful info I'm looking for. I'm not going to use the ph up anymore- instead I'll focus more on my soil, let it do it's job. My water does have very little calcium or magnesium so I have been supplementing with calmag. In the long run I think I can remedy my problem...

Yes, judge mental, sodium bicarbonate is baking soda. True, alwaysgreen, my ph is what it should be, but at what cost? It takes a lot of ph up to get there. I've read that some people think that too much ph up is bad. I just want some confirmation/clarification. I know if I post pics I will...

Anyone else?

Good to hear, mrblu. I think I'm going to follow suit and ditch the ph up. My problem now is how to correct the issue I've caused by using too much potassium bicarbonate(ph up) Potassium deficiency or toxicity? Thanks for the reply.

Thanks Silky, I wish I had realized that earlier.

Thanks for the reply, BSD0621. I do use dolomite lime in my soil, and I'm starting to wonder if I should bother with upping my ph at all anymore. It appears there are two completely opposite schools of thought on this subject. I'm trying to diagnose a problem though, so I specifically want to...

My well water has a ph of 4.7 so I have to use quite a bit of Ph up to get to 6.5( I grow in soil-FF OF) I use Earth Juice natural up, in crystallized powder form. It's main ingredient is potassium bicarbonate. My question is: Is it possible to use too much ph up? Does Potassium in this...

John, Not sure why my water has such a low ph. I think it is a common ph for the ground water in my area...I blame glaciation. I'm not treating the water with a softener but I think you might be on to something: I use Earth Juice Natural PH Up, and often require lots of it to get to 6.5. This...

Thanks for reply, JohnDee. I'm already doing that to no avail. Nothing else stands out to you?

Hi all. Long time onlooker, first time commenter(I hope I'm in the right place, if not please let me know) I've had an issue with my last two grows that I presume to be a deficiency, both times manifesting itself about 3 weeks into flowering. I know this may be unorthodox, but I'm not going to...
