You need to pick one or the other. Hit them with nutes in a feed or use slow releases. Mixing them can have bad effects. It can be done but that's something you will learn with a little more seat time. I'm not a soil dude so hopefully someone will chime in on soil NPK's.
From what i understand, same thing with RO, you never want to use pure distilled or RO through plants. Even when flushing. You always want something in it. If I remember what I read it has something to do with the interaction with calcium and osmotic pressure differences it can cause. Same reason why it will kill PH probes. This is out of my realm of understanding and maybe someone else can chime in with more of a chemistry background but I remember reading about this doing nute research. I could be totally quoting this wrong btw. Hopefully someone who knows wtf im talking about chimes in since it's in the morning hrs for me and i'm cross eye'd atm and I haven't used RO in years.
With that being said not knowing what the PH going in is would be something I nailed down first before I look to other sources of problems. Pool/Spa test kits can be bought t a lot of different stores for cheap and the little shake tests should be plenty for what u are doing.
Also replanting/repotting will shock the plant. Best thing to do when you do this is leave it alone for a couple days before trying to fix something. you don't want to immediately start trying to flush it and run nutes through it. Again I'm not a soil dude people with way more experience in that field then me.
you might not think your a soil guy,but you nailed it right on the money chris,soil hydro soiless there all the same when it comes to plant picture and problems,OP have patience first off,the plant just dont zip up and you smoke it.
first off i cant tell if it is soil or coco,there are difrent methods of medias,first off do a slurry test if it is soil
next get a ph pen or strips,guessing what it is probally the biggest problem right off the bat,even other countries have ways of checking ph,i realize a lot of countries dont have ebay or amazon,but all countries have swimming pool company's.
next you replanting isnt doing anything but stressing the plant more,stop
flushing ,why,really why,you made a mistake with all the difrent nutes your using,as chris said choice one,flushing might be a good thing in coco,but soil it isnt,you wash any life from the pot and then have a mud cake,that goes anerobic,stop ,if you have a issue with your plant,dont feed ,just water the next trip,when you need to feed again go half what you used before that caused the issue. this is considered flushing in soil,not drenching,but just when you get runoff,it washing the unused salts from your pot.same with any soiless mix,that runoff is the minerals not used that why folk say 20% runoff,i dont do the 20%runoff cause i dont over feed,when i see runoff i stop,all that in the media has to come down to the runoff because of gravity,so there is your 20% in reality.
now you say you cant get nutes there i dig,so do teas,if nothing else compost earthworm castings manure combined make great food for you plants,put handful of each in a bucket with water let it sit in the sun a couple days and feed it,done you just feed your plants,with your nutes i asume they are dry amends,top scratch it into the soil once a week and water the other only,anyway biggest issues you have is not knowing your ph right off,your water or feed should be at 6.5 for the sweet spot,with correct ph going in you off to a great start and washing what isnt used out,hope this help
