Sounds more appropriate for a hydroponic system to me. For organic soil I'd think a sulfur based amendment would be more effective at lowering soil pH. Something like: https://www.espoma.com/product/soil-acidifier/

I have read conflicting information on this. I have read a lot of information suggesting using nutes in the reservoir is just fine. So I am going to experiment with it and see what works. I was going to use Chempak soluble nutrients. I have seen multiple videos on growing various fruit and veg plants and they all say it is fine. I am going to do some tomatoes, one reservoir fed and they other with dry amendments and see what happens.

I would think that would depend on the medium correct? Neat experiment tho and I hope you share with the Rollitup community!

I have too many Ca inputs,ie.. my tap water. Gypsum just adds more.With adding dry amendments like Gaia 444 it has lots of Ca inputs so need to lower ph without adding Ca

Im just going by my last grow,nutes added to the top watered in is ok.Nutes in the res not Ok lol
Feeder roots are on the surface, water roots in the res. Top water nutes, youll be happy.

There's also elemental sulfur, as in pure S. I would assume a little goes a long way in that case...

If I have to top feed nutrients then what is the point of a SIP? I want to be able to fill the reservoir and walk away for at least 4 days. Dry amendments are a really expensive way of feeding a plant.
For the first 4 weeks they will get just water as my medium is good for at least that. I am drawing inspiration from videos like this...

Thats DWC without air, not a sip. Tomatoes seem to do ok with that.

That sounds like a hempy bucket to me.
Dry amendments may be expensive (debatable), but in my mind it's worth it to pre-load the soil with them. I use 2 pre-mixed dry fert blends, because I can't be bothered to source all the individual meals and flours and such. I fill my SIPs' reservoirs with plain tap water every 3-4 days, top dress a couple times during flower just for peace of mind, and that's it. Doesn't get much easier.
In my mind it's important to have the right amounts of medium and nutrients for the right sized plant(s). If you get that down, you don't even have to top dress, just add water to the reservoir. And once you get a feel for how fast they empty the reservoir, you can automate the watering with a timer and almost never even have to open the tent...

If you want to leave for a week i would use a drip system.long time ago i bought some asian drippers its like a porculan spike with a hose.it drips 1L a day

I grow in a attic. I have to be able to get everything, including water, through a 2'x2' hatch.

You use a cable less than an inch its really cool i got a pack of 4 for 0.5dollars
Question-
I just finished my 3rd grow, first time organic, first time SIP, first time with a new-to-me HLG light, first time growing a Mephisto autoflower (not my first auto, just the first of theirs).
Is 10 ounces a decent yield? 2 ounces was larfy stuff I water cured for edibles. Should have done some training I think, but I really wanted to see how it grew naturally.
My CBD plant yielded 2 ounces. It was a stumpy thing but smelled great.
My first 2 grows gave me about 3 ounces per. I think I’m good on bud for awhile, but damn, I’m ready to get some more started.
LOL

I would say that depends on what your expectations were going into it. Also a lot of of other things lol
If your happy that’s all that matters! I can’t wait to do my SIP setup
I was thinking around 4 ounces, just less maintenance and less chance of killing them by over feeding.I would say that depends on what your expectations were going into it. Also a lot of of other things lol

Yep, I’m happy with that.

Week 3 down....
I believe she's done stretching. What a relief. I trimmed her up a bit too.
I just top dressed some dte rose and flower for the first time tonight. I wanted to try it out and see how it does. Also some ewc, some build a flower, some kashi blend, and I watered it in with 500 ml of build a bloom. She should be good for a week. Lol
