    I am having the same problem with the last bag of #4 that I got. I was undecided if it's the soil mix or something else. I think my pH was too high at 6.5 ish. Forgot it's a soilless mix, so pH should be more like hydro. I add 2 tbsp of dolomite, a tsp of azomite, and 3 scoops of Great White to each bale, and it has worked well until the last few days. Wonder if it WAS the sunshine mix, after all.

    Looks like a phosphorous deficiency, which is what an overage or lockout can look like, too. I'd give a push of phosphorous, because your other numbers look pretty good. Oh, the ppm #'s, what conversion factor is being used?

    Im on the .5 scale. I thought phosphorous.....it is possible that its locked out. Im using 10g pot so i dont get any runoff...which sucks cause i cant test it. So my Ph is based on what its going in at. Im gonna try one of those 3 way meters to try and get a ph reading. Thanks for taking a look guys.

    If you're not getting run-off, if it were me I'd take a sample of the mix, then take an equal amount of either distilled or 0EC RO water and mix, allow to set for 5-10, strain then test for pH and EC. Depending on where it's at, you may or may not have to make adjustments.

    Good idea Seamadien, i think thats more reliable measurement then the 3 way meter.
