In ProMix HP and SIP's I have found they don't care, watered from the top to full reservoir and they just keep on trucking
FYI > on my last grow I increased to 4g/gallon on day 48....

Day 45 - Veg Day 25 of 48ish:
Well on the positive side they are still growing! Having to continue the tuck under the net daily.
On the flip side they are not getting better and the issue seems to worsen looking at yesterday’s pics to todays there is a noticeable difference in color. I am still optimistic that I can get it turned around with some additional Mg. Going to take a hard look at the numbers this weekend and hopefully have more answers than questions.
They both still have a 1/3 left of their reservoirs so that are not drinking much so the initial addition of epsom salt hasn’t fully kicked in. I’m assuming if it was a Mg lockout that a flush and 1 addition of epsom salt is not enough to stop the lockout and reverse it’s progress?
Time will tell

The flush should reverse the lockout but Mg def is slow to show and slow to recover.

Day 48 - Veg Day 28 of 48ish:
Twas a busy weekend so didn’t get a chance to update.
Ladies are looking a bit rough
no real signs of them turning the corner yet and I am hoping I am actually able to save this grow before the get much worse.
They are still growing though! But lots of damaged leaves on both of them….
I am working on figuring out where my efficiencies and deficiencies are between my water makeup and my nutes as this seems to be the problem. Once I get that worked out it should be easy street!
Until then I am on 4.5gr/gal of MC and 1gr/gal of Epsom Salt to increase the magnesium.
I will however continue to match my weekly DLI and VPD goals to give the best possible environment I can, or at least attempt to haha.

I think my first instinct would to be hold off on all feeding and stick to rain or RO for water depending on your situation for at least 2 weeks if that’s soil. Don’t know crap about SIP but they definitely appear to be struggling.Day 48 - Veg Day 28 of 48ish:

It’s Pro-mix and already flushed them on Thursday I think it was with 5-7gal of water each
Hopefully I can get them turned around!

Yeah, I’d give it a couple weeks and see with no food or toppings, then let the SIP experts guide on feeding. If new growth improves you should be good, wouldn’t expect much if any improvement for the already damaged leaves.It’s Pro-mix and already flushed them on Thursday I think it was with 5-7gal of water each

Are they still drinking as they were before they were showing any damage? I'd be curious on the pH of the ProMix now since I had issues with MC and ProMix.

I did a slurry test on this bag of ProMix I have and it came out to 6.0 on the nose.
That's a bit high and would be higher still if you wet it and tested a few days later when the lime kicks in. And now it would be even higher with the MC and its high nitrate content. That's why I was curious.

I ph down after nutes to 6.3 think I should go lower?
The pH of the nutes doesn't matter. I think it might be a good idea to do a slurry test on the ProMix in the SIPs. Grab some from the top and dig around down the sides to get a mix of different places. Then distilled water and stir!

That’s exactly what I did last time and it came to 6.0. I should have specified that, I haven’t actually slurried the stuff from the bale before it has been used.

I’m going to run it again though just to be sure. Equal parts promix to distilled water right?
Yes, or a bit more distilled water if equal parts won't stir. Mix it every 15 minutes for an hour and make sure your pH stick is accurate.

Just calibrated and the first reading is 6.2.
6.2 is the upper limit according to the manufacturer of ProMix. They really want it in the 5.6-5.8 range.

Second reading is at 6.3
If things don't improve you could try the sulfur again. I can't remember if that helped last time or not though.

I didn’t add sulfur last time I added dolomite lime. And I think it did help but then again I made a bunch of changes at the same time. Though all of those changes minus the like I’ve been doing this entire grow.
It just jumped up to 6.4. Would it be easier to just ph down to like 5.6-5.8 rather than the lime?
