Interesting about the pH... I am also on low ppm well water, I think having them test it would be a good idea.Yup awesome thread, helped me a lot because all the initial info I read on this was just use the 2 parts and you're good to go, but now I see a lot (if not most) add epsom salt to the mix and that would be why my plants (especially one of the strains) are showing MG deficiency. I'm also glad I read this because I finally decided to switch to EC mode on my Blue Labs meter and realized why my plants were burning a bit at 600ppm (was using .5 EC conversion). I'm at 1.1 EC now, plants are getting big and I'm about to change to 12/12.
I ratio I was using used a little more of the cal-nit than mentioned here, so I bumped up the base stuff when I topped off this time. Also added half a gram (per gallon per my concentrated dosing) of epsom salts and I'll add more afterwards if needed, gave them a nice foliar spray couple days ago and they are turning around.
So the general consensus seems to be to basically use the same formula through flower? For anybody here who dials back on the cal-nit, do you find you need to supplement additional calcium?
Also, didn't see much info regarding PH, JRPeters claims this line of nutes is good to go at up to 8PH I believe. My water is 80ppm (well water) and have had it tested by jrpeters and it's very clean, but it is 7.8 PH. I just started using modest amounts of PH Down (half nitrate form, half potassium) to at least get it down to 6.6. Should I trust it without PH Down or do you guys feel I'm doing the right thing, or should go even further and get it down to 6.3 or so?
Can you explain this further?: I'm also glad I read this because I finally decided to switch to EC mode on my Blue Labs meter and realized why my plants were burning a bit at 600ppm (was using .5 EC conversion). I'm at 1.1 EC now, plants are getting big and I'm about to change to 12/12.
I have the same meter and have not switched to EC, I figured 1.1 EC was about 600 ppm...
