Ive got 4 Purple Rock Candy ladies 3 weeks in flower and one of the girls just isnt happy and needs additional magnesium.
Ive been pushing Demeters and adding amendments but it just aint doing the trick.
What is the recommendation for a bottled cal/mag that would be friendly to the calcium based line?

Thats the amendment I tried. Though I hadnt tried adding it to the feed water, I just worked some into the top of the potting soil.
At this point she needs attention pretty quickly as Ive been fighting this for a while

Could your media have gotten too acidic? Just from what you’ve said - adding adding and worse - I wonder if you need to bring the pH up.

Do you use the liquid lime or adjust some other way?

For sure it drifts lower, always. I was using distilled water so that wasnt helping. Ive added lime (granular as top dressing)to address the constantly falling soil PH and Ive added Epsom Salts (the garden variety with added Sulphur) also as a top dressing. 3 of the 4 are fine but that 4th has some funky leaves.

See above.
Also, this is the 1st time Ive ran this nute line from seed to flower and this is just part of my learning curve. But yeah Ive been fighting falling PH and what appears to me to be a mag deficiency.
Ive watched many episodes of Oregons Constant Gardener with the owner of NFTG (Scott Ostrander?)on Y-Tube and I know that having your PH off can mimic a lot of things so Im gonna do a slurry test to see of maybe its just PH. I have to wonder with 3 other girls that are looking fine.

No worries! There is a full on thread here that I just recently saw for nectar line if you search. Those dudes would get you dialed in perfectly.

The whole line is acid except Zeus which you don’t need right now and then the liquid lime, Olympus up. Any lime would help but I really like theirs honestly. Its potent. Once a week they get their bone meal with 2.5 mls liquid lime and it resets it. I’ll use a few drops with heavy feeds too. Demeter’s is potent and can keep up so I have a feeling this is pH low here.

NFTG. Nectar For The Gods

Niiice. Got an even better understanding now what to do with my slurry data. So bk not only has the plant uptake calcium at a more rapid rate but other nutrients as well. So as long as my soils in range bk is all good and when the ppms are on the high end I can up it. As long as soils loaded and...

Let’s start with the slurries ….. if ph is low that cause your ppms are sky high or your not giving enough herc and herc should be used with every root drench expect on tea days .. but let’s see that slurry 1st then get you dialed in …

Bingo. …..what you can do is double the feed … and next root drench check your slurries again … or if you do a normal feed you mite have to do a feed feed feed ….

I have not had a PPM reading that low, like ever. I hovered around 500-600 pretty consistently. I was using SLF100 and Recharge and continue to do so but when I added Photo Plus, thats when the PPM numbers really bottomed out. Indicating those microbes are working!
Now I rotate through all 3.

Thanks for your input, I really appreciate it

I havent had a slurry register anything higher than 500-600.
I was using (in the plants young life) distilled water, which Scott Ostrander has said is not a great practice because your PH will fall (I paraphrase) and so I began using Dechlorinator+ which is a whole lot easier and leaves my cities hard water with its calcium and other minerals in the mix. Much easier and I think much better.
Insofar as Herc is concerned, yeah I think you're right, I havent been using enough herc. Just ordered 2.5 gallons to remedy that.
Happy growing!

Good stuff! I’m just getting the hang of it myself. I shouldn’t have assumed HH overload. It’ll catch you up no prob. Stuff is aptly named.
