started grow question 5y ago
Say if I get a high reading of 800ppm from runoff. And my goal is to be around 650ppm. Would I just flush and bring it down to goal? Or am I just to feed less next? Still trying to get this ppm stuff, cheers.

answered grow question 5y ago
U can flush to force the salts out. Or u can water with balanced PH water. a few times (Or however many it takes) until its 650ppm or below :)

Water ph for promix Bx (soiless peat).. also can fert for soil work with promix bx?
Hi, if anyone familiar with promix bx, it is mostly peat so it count as soiless medium. So can I use soil nuts or hydro nuts? I currently only have soil nuts can it work if I adjust it to hydro ph(5.8-6.2)? And should the ph be hydro (5.7-6.2) or soil ph (6.5)? Confused, pls help

PPM run off higher than Solution PPM (Soil)
Nutrient solution at 550 ppm - 6.2 PH, I water the plant and get 15% run off which read 1500 ppm - 5.9 PH. My plant still look healthy no sign of deficiency or toxic problem. It's the TDS in soil still remand or salt build up this case. Should i flush her next turn.

low pH problems
I discovered that I had irrigated with water at pH 3.5 for at least 5 days. yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

Can I combine treatments into one?
My question is pretty simple. I wanted to give my plants a light foliar treatment and also wanted to include some neem oil. Is it OK to mix the two together or should I do it separately? I'm sure it's likely fine to mix them, but didn't want to take a chance. Thanks for helping!

Hydroponic PPM and feeding. How do I match magnesium sulphate to potassium for flowering??
Do I got this right? Hydroponic Flowering cannabis eats at a rate of 1-1-2 and for maximum useage, feeding 1-1-2 makes sense. Extra nutes outside the ratio is wasted and extra. You want highest PPM possible before burning. Will extra Cal-Mag burn roots/leaves?
