Coco grow Ugh issues

My well water is about ph 8, and With nutes about 7.6. I can drop it to ph 5.8 in the morning, and by noon it’s up to ph 7.4. A total pain in the ass. With the ro filter I add the nutes and it’s ph 5.7, and at the end of the week it’s ph 6.1or so, it does fluctuate some depending on the plants stage and how much they are drinking, but still in acceptable levels as far as I’m concerned. It’s much easier for me to filter some ro water once a week than to chase ph every day. I wish I didn’t have to and don’t like it, if I could use my well water I would, but in some case an ro filter is easier and more consistent

I will say switching to tap has stopped all of the issues I was having with Jack's and Mega Crop before it. My plants haven't looked this healthy since I took them off of Canna Coco about a year ago. I'm preventing a ton of wastewater and saving a small fortune in filters.

I’m going to start using mega crop. May I ask what your tap ppm is? I have hard water at 330ppm but I also have access to mountain spring water that comes out the hill side at 40ppm so just wondering what is better for the mega crop before I start and run into issues. Thank you in advance

It's around 200 ppm. I had issues with Mega Crop almost instantly, so I switched to Jack's. On top of my plants showing deficiencies, the salts were falling out in my res and gunking everything up. Some growers swear by it, so I don't know.

MC is decent. Usually not 100% soluable. My main gripe with the one part is the inaccuracy with the scoops. Usually was very nitrogen heavy.

Switched to Jack's and have no plans to ever change to anything else.

I will be trying jacks after I use up the mega crop

Lots of info here. So with 14 day old seedling I’m going keep using R/O and feed it 1/4 maxibloom with 1TSP of calmagic for now and see what happens. On other seed I will try my tap water and 1/4 maxibloom no calmag for now and give it a go. My meter reads .05 and 1/4 of maxibloom and 1tso of calmag came out to 625 ppm

Skip the CalMag. Is there a reason you think you need it?

I wouldn't feed seedlings 1.25 EC either. Start them low and slowly increase the feed as they grow.

No reason just read people go up to 200 ppm when using R/0

I used to calmag my RO water to around 200ppm when I was using Canna Coco. I never had any real issues. Although most of my problems after switching were magnesium related, so the extra calcium may not be necessary. Still, it probably won't hurt.

Your going to cause issues like lockout when you're adding extra calcium and magnesium when your nutrients already contain plenty. You'd be better off reacting than overreacting.

Thank you. So much info. I will germinate a new seed this weekend and have you guys see what I’m doing from day one. If I water everyday my coco when a seedling I get no root growth like others do. Im using 70 coco 30 perlite

He's using RO water. I did it for many years without issue. I know your tap has hella low PPM, but it's not RO. When I cut out the calmag my plants suffered. When I switched to tap all of the issues went away. I used Canna Coco too.

Also what you're saying is people who use tap are going lockout their plants.

How does RO create issues? What's the TDS of your tap water?

on my tap water 135 TDS -(soft below safety std for drinking)
Guess I should explain the issues with ro-
RO- is best for true hydro ( DWC) no soil/coco base, have found to many new people start off with ro and end up having to add shit all the time to fix issues with the grow-- easy to use tap water with cal/mag in it that way just add nutrients seedling stage- 180-200 PPM- , after 1-1/2 weeks go to 600 ppm, in flower I go upto 1500 ppm just how I do things in coco(100%), dont see the point in ro these days -

dont use PH up----- use silica only for PH up as the plants love it

Damn maybe I should stop using tap then eh?

You're saying adding calmag to RO water is going to "cause issues like lockout" because "your nutrients already contain plenty." Tap water already contains these elements. I probably didn't need to type this out though. You're not dumb.

I said adding CalMag in addition to nutrients that already contain sufficient calcium and magnesium is likely to cause lockout.

Trying to compare CalMag to tap water is pretty stupid.

That is pretty stupid. One is a bottle of a calcium / magnesium solution that you add to water. The other is piped in water, enriched with elements including calcium and magnesium.

I'm sure you'd agree their concentrations of said calcium and magnesium are vastly different too then right?
