Well, today was the first time I felt confident enough to flush my MG MC 6mo... It was a good thing I did as I was experiencing some salt toxicity. Got this from fighting root aphids (got them quick) which required some soil drenching and drying out and what not...but the salt build up was pretty bad... the first TDS reading was almost 2000 ppm. I flushed until I got down to 340 ppm and tried to get ph back to 6.5. I noticed, while I was using tap water with a ph of 9.5
, that the ph would stay around 5.9 to 6.0. This is why MG users really have to use cal/mag a lot more specially since the soil keeps dropping down. I have roots organic for my next soil as it does not have the moisture holding material, but it still uses peat (which I understand is a hot ingredient in the soil). It will be interesting to see if I can keep the roots up around 6.5. The girl is recovering and still has a bad cal/mag deficiency... but it looks like P, cal, and mag all need around 6.5 or greater for soil uptake... It will be interesting to see if I can keep on top of it with periodic Epson salts spray before bed time. I hope I have better luck with roots... looks like I will be going with FFoF next purchase. I have four 5 gallon smart pots and the roots will only be enough to fill two of them... so the other two I will try FFoF. Out of all the soils that I have come across on the forums, FFoF seems to be the route to go. Will reply again as she recovers from her flushing and getting more Epson salt foliage feedings.
