no just noobs make it look hard by overcompensating it . you literally need 3 products. a+b nutes cal mag and ph down plus water that isnt shit.
it being synthetic is a different topic but its no different . npk and all micro nutrients are the same to a plant regardless on how its absorbed. i say growing soil indoors is way harder and allot more guess work
A+B nutes if they can provide a buffer. Or use tap water.
Hell I don't even do that I use a 1 part and tap water with some ph down

this is my first auto with this much of a root system, i honestly underestimated its potential. I had been thinking the same thing when i pulled it out.. it makes the rez way smaller making swings super dramatic possibly.. roots have like 80% of the bucket now it looks like.

should i run a mix of dist and tap next res?
At this point its just gonna be a battle keeping anything stable. I would try a 50/50 mix but you may end up doing res changes almost daily

i love the idea of running something bigger in my tent, i was thinking about going out and grabbing a larger cooler
somthing like this
https://www.walmart.com/ip/Coleman-50-Quart-Xtreme-5-Day-Heavy-Duty-Cooler-with-Wheels/149949357
but i have an 8g tote from my last run and it did me well, it was just to omuch room for my last auto.. do you think rootball is going to need somthing more? this seems like a larger strain of auto as its really filling its home out well... also i need to be super quiet.. my worst enemy is droning vibration through the floor so the bigger the rez the more air bubbles i need which usually means larger louder pump so i was trying to avoid

I had been taking a look at the data logs from the past 2 days somthing seemed off, I find my light timer was off, and running my lights 24 hours.. I recently had a fault in my house and had to resort to using an old 2 prong outlet to run my entire setup off a jump pack and i had to take off the 3 prong timer and run the light straight.. i had forgotten to put it back on.. so 2 days full 24 hours instead of 18/6, although temps and hum were in check this deffanitally played a role in the drooping, would this explain the ph swing? my plant is stressed heavily today ph is back down to 4.5, but it will have a new home soon

I didnt read the whole thread just the first page, justw anted to drop a tidbit here that using a 4gal res could be half your problem here, such a small amount of water can be hard to dial in, why not upgrade yourself to a 10 or 15gal barrel?

most people now dont even bother with DWC (which is what i assume your doing even though you havent really specified that) they do RDWC where their plant buckets are all connected to a control bucket and the water between all of them constantly recirculates. Also you mentioned somewhere in here that you applied nutes through the top of the plant??? never... never again. nutes get mixed directly into the water, preferably one nute at a time with enough time in between each to allow it to fully mix in, if youre using any kind of silica product that needs to be added first.

I think you my friend got pythium root rot! Most common issue with DWC. I use Polysorbate20 and chlorine when I need to treat an outbreak. Last couple of years I've helped friends combating this issue.
Polysorbate20 work as a strong surfactant removing cyanobacterias ability to grasp on to roots, linings and walls. Chlorine is used for oxidation and sterilization. I run 100ppm of Polysorbate and 5-10ppm of chlorine. I also usually add some light feed and run this solution for a couple of days before doing a res change.
I have never used H2O2 but I've seen many people having successful results with it. It's a very strong oxidizer so it's easier to overdo and burn the plants with it.

Wanted to ask a question after things got resolved.
I enjoy your posts and knowledge.
Is it correct that heat/light stress slows down transpiration?
I thought heat/light stress increases transpiration.

Yes transpiration rate increases with light/heat stress. Photosynthesis slows down because the plant draws nutrient from nearest point of entry trying to hold on to water/moisture. Potassium deficiency is almost always a result of light/heat stress.

water uptake increased by half a gallon per day during this mishap
