Lockout question

Hi all !

I just did a res change in my 4x5 gallon DWC . My plants are one month and have been topped two times .
I set my PPM at 845 . the day after I read 851 ,day after 863 . I think that's a lockout !?! My plants look good ,tight internodes ,but are a little slow . Now what do I do ? Flush with ph'd water ? How long ?
I have tap water at 120 ppm ,and I added 2.5 ml/gal. of calmag ... I think that might be the cause .





Thanks !

Boris

sounds like overfeeding, you're fine if you just top off with tap only until you see ec levels drop again proving she is eating. when mixing nutes, add calmg until you have .4 ec, then add your nutes to your desired ec level. at that size, they probably dont need more than 1ec

it is if your meter is .500 scale. some are .800 scale. ec is best unit to measure by for hydro

I believe you should check your water report and see what it's composed of, generally from all the research ive done since I started growing a plethora of people that use tap don't mix cal-mag in as well. That's more of an R/O and/or LED thing.

Also when I tried to use my tap water (70-100ppm) for hydro the first time it was a tiny plant as well, now this can be from chlorine/chloramine or just bad new growing habits, I dunno but there's my .02.
