Guys PH is a result… it doesn’t in any way shape or form tell you anything about the influence it may or may not have one ANYTHING added to it or ANYTHING its added to.

We really need to change this eay of thinking

Okay wow I got plenty of replies while i was away. Little new to the site so im going to reply and tag as best as I can , I appreciate all of the replies as i go through these troubles.
@GNick55 @Aqua Man @TSD @Heywood @Deadstill @NorthernOrganics
I did raise lights as they got taller. Right now lights are 1.5ft above tallest parts of the plant. Im using a Marshydro LED 300watt & its non-dimmable, I use Primo purified drinking water.
I will post a lineup of all the items im talking about. If its root rot how could i check? Could my 3gall pots be too small? @GNick55 I also think all the flushing mightve deprived it of nutrients but as soon as i added some it went droopy the next day so that confused me. I try not to over water either i only allow a slight run off and i try to make sure it has a dry period i check the weights of both and one does appear to get lighter than the other quicker but that might be to how much soil i have in the other i think. Ill show that as well

So before coming here i believed it was a salt build up due to too much PH solution in my nutrient solution so i started flushing w/Hygrozome & now that ive been adding Nutes in w/ no ph solution at a PH of 4.5 ive got yellowing , brown spots & theyve been droopy more often now on the clone my other plant has been saggy and some leaves are dry and crispy falling off w/a small touch.

So far reading through the replies some of the ones I had an alike thought with were; an issue with watering , maybe too much or not enough nutrients.

Also PH but my Ph was good up to the point of adding nutes so not too sure how fast those issues arose but I’m stumped on what to do next would not like to put into flower if they are not perky / happy. My thoughts were to flush all over again but i might deprive it of nutrients especially my left plant that has lost many fan leaves already & is at 8 weeks of veg already ahead of the clone.

Aha enzymes in soil, what for? Bacterias can do that job and these actually suffer immensely from pH swings. I'd do a slurry soil test to see where you are otherwise it's just guessing. 300ml RO + 200ml moist soil, shake 1 min, filter and measure pH & EC. Should be in the range of 6.3-6.8 and 1.5-3 (the latter in organics, that tolerates higher) and if not you gotta correct.
Also calibrate your meters and look at your watersource, because adding nutes and calmag shouldnt make it so acidic or is that some berry fertilizer?

I think he was talking whats going in? And i 100% agree PH swings are an issue which is another reason not to mess with it in soil

Super busy at the moment, didn't have time to read whole thing yet - I will say I've seen plants droop like that from pH issues within hours of feeding wrong pH. I'll jump back here later when I have more time

i think or i’m pretty sure that when you starting using the ph up/down solution which is synthetic in an organic medium with organic nutrients you severely screwed up the soils natural ph buffers, creating what you see now along with couple other things that happened because of trying to fix it..
your best bet or see if others agree or have better advice is from this point forward is raise the light to 25-30 inches, just wait till plants need a watering/feeding and now use your ph stuff for every feeding,
wet/dry cycle, give it a week or more to see how growth is going and looking.. cross your fingers in the meantime..
faded/yellow/browning leaves will only look worse in time, they don’t get better but can kinda be stopped from getting worse..
wait and see what others think as well..

He said the PH of the nutrient solution was 4.5... but what is the plain water PH and the actual soil PH... because isn't that what really matters? I dunno I don't usually mess with PH unless I have an unidentified issue just to rule that out.

You are using water that has been stripped/filtered and had food grade minerals added for human taste buds. You should switch to tap water for the alkalinity/buffering. This will solve your pH problems. If you are going to feed bottled nutrients to soil, you must water to runoff and only feed 1/4 the dose to start. It is better to feed the soil with organic inputs, topdress or bottled.

So keep flushing and lights raised till they seem happier with no nutrients ? @GNick55
I believe I tried that except for the light raising , They were real happy with pure water and hygrozome by 2nd flush so I added nutrients on 3rd watering (3rd watering after I stopped using PH solution in my organic nutrients) and that's when they started to sag all over again. Should I remove damaged leaves as I'm flushing?

I had the assumption that my tap would be harmful to cannabis since they use chlorine & fluoride to clean it out.

no don’t keep flushing never said that..
but i agree with using your tap water instead of what your using..
just feed as normal when time comes, use tap water and i’m guessing to ph your feed before giving.. i have no idea about ph stuff as i never bother..
but there is sine great advice here from others..

and just leave the bad leaves for now.. the more you do more than likely it’s causing more stress..
let’s just get her back on track which will be a week or two..

I think of you leave it out uncovered for a day or so the chlorine will dissipate... not sure about the fluoride... but yeah if the water you've been using has added minerals and you're adding calmag... that could be part of the issue too. I don't fuck with calmag anymore, every time add it shit goes sideways... If you're using a good nutrient and proper water it should have enough really... but I dunno, everyone seems obsessed with adding calmag for every ailment lol. I added it this spring unnecessarily and my girls were so unhappy a few days later I actually transplanted them.... they were due soon anyway.
