I’m like you Pute, I have to lower my sink water from just around 7.0 to around 6.5 every time I water. It seems now that if I would use my sink water at 7.0 ish, it should take care of the problem. I’ve never been one to measure runoff but now that I’m measuring it I’m surprised it’s low.
I’m starting to wonder is it the FF happy frog. That soil gets right with your pocketbook too but I switched from ocean forest soil after everyone complained it was burning up their plants. I never had a problem with that so I probably shouldn’t have switched over to the happy frog. I don’t use a lot of nutes or additives and depend on that good soil to provide nutes to my plants between transplants. I do use fox farm nutes but don’t go crazy with them just feeding the last few weeks of veg and thru flower. I also add cal mag every other water. I will add perlite to the bottom and top of the soil tho that’s a good tip as I do wonder if the roots are soggy down there. Also I’m going back to the 5 gallon plastic nursery pots as I’m not sure how much I’m loving the cloth pots. They do seem to work ok outside tho. Maybe I will put a little dirt in first then a layer of perlite so the perlite don’t leach into my drain pan. Thanks for the perlite tip
Older thread I know, but I he have been having what I thought were simple ph shifts.
I also used FF soils, frogg and the Ocean Forest. I had ratty platinum GSC do the same crispy thing. Like you, I powered through and actually got a good yield of good pot.
Recently I posted PH related threads and after much back and forth came to the conclusion that it is the FF soil. I have had excellent results some times and sometimes not. I measured run off and so forth like you did with similar things happening.
The final cure was I realized the FF just is not always a consistent product. One bag worked, one bag wouldn't.
I started collecting all the parts to duplicate gmo's areoponic tote, and will build it, but first tried semi hydro with Promix. Got this info from pute, who also uses AN nutes along with Promix.
I am not looking back! PH probs vaporized, garden back lush and green. I am a promix convert.
