Top dressing is directly related to the size of pot you use. The bigger the better. My 10g sips are just too small for bigger plants.Great topic. I am pretty new but really trying to learn the dynamics of keeping healthy soil and reusing it over and over so be lurking around this thread.
This is true but using same dirt over time, like years, you'd think it has to build up.Some of my soil is almost 2 yrs old now.The calcium in your hard water May not be available to plants.
My water is extremely high in calcium and magnesium and I use it only when I must.
When I did hydro my res had a good white film on it,used CLR to clean it off.This is true but using same dirt over time, like years, you'd think it has to build up.Some of my soil is almost 2 yrs old now.
Peat is my go to for ph down tooI also reduced my lime input to 3/4 cup from 1 cup per cuft.
I think Ill add some plain peat to the older soil for a little pH down also.
Initial fertilizer should have a P input, but re-ammending should not have PIs that even a word?
I know we should go by how are plants look and what seems to be low ,but in general do we use a percent of what we used when we first mixed?
Or Is it as simple as just add back the same amount of dry food and cook again?
Ill be on my 4th round with this soil,it needs help.
What say you?
They look nice for sure, but I dont think the yellowing is from N alone. I'm willing to bet that it's iron chlorosis. Maybe a little of P toxicity? Read up on the problem before you dismiss it anyways. I've been dealing with P tox pretty often.

P tox which pic? This round I was leery of Ca tox so was top dressing with kelp,alfalfa and frass.Almost no P other then the little 444 I added. Thanks.They look nice for sure, but I dont think the yellowing is from N alone. I'm willing to bet that it's iron chlorosis. Maybe a little of P toxicity?

I wasn't saying that you had a full blown P tox issue and your buds look great. I was just sharing a common issue that I have, actually dealing with it now. My last soil test said I was low in P, so I listened to my agronomist and added bone meal. Now, I'm dealing with micronutrient deficiency. I stopped using fish for that reason also. There are other ways to chelate micronutrients other than using fish. I started using soy bean meal and bottled humic acid, it's the only bottle that I use. The whole reason behind Clackamas Cootz recipe was to achieve lower P, just a thought.P tox which pic?

Oh and why no P for re-amending?
Ok I’ll look that up. Cheers.It was Tad Hussey on KiS Organics that said to not re-ammend P. He also suggested getting your soil tested to take the confusion out.
