Sorry for late reply work calledWelcome to the farm. You've come to the right place.
That's a lot of nutrients for a seedling. When you see salt building up on hydroton and you are still on your first node - you may be loving your plants a bit too much. Number one problem with new growers is over feeding / over watering.
I'm struggling to see what you have going on there, are these net pots sitting in a 5 gal bucket? Where is your water line compared to the bottom of the net pot, and are the roots all the way exposed yet? Looks like maybe you are top watering at the moment?
You say your light is 2500W, that is the "rating" and not the true power, correct? Maybe an Amazon blurple light?
You re-mixed to 420 (hehe weed number. 69. I'm a child) but you didn't say your start number - is this tap water?
I think maybe the cold slowing down your early growth has helped you not to kill the seedlings being over fed. Easy to get this all sorted tho. Fill in some blanks for me and I'll help ya.

So in regards to water it was reversed osmosis. Water with no ppm and I added 15 ml calmag first gave a hour that is what brought my ppm to 240 then I added 1 ml micro followed by 1 ml gro and 1 ml bloom then a aggressive 10 ml of rapid start all in that order after mixed it was a little low on ph like 4.1 I wanted to add water to bring up and raise ph but went to add ph up since I was low on water atm . I’m about 3.5 gallons in the 5gallon and I hope a significant amount of roots but I’ll let you be the judge . water line is 1 inch below my pot maybe 4-5 inches of roots are submerged in the solution with air stone .
The top feed look is the top layer of hydroton was never washed I added and after a few foliage sprays with 7.0 water I think the lime or whatever maybe made those rings once dried ? Idk lol
And in regards to light it’s a bloom plus 2500 I haven’t went and recorded the actual watts from amps but will shortly do if it helps . I also have a 300 watt mars hydro that actually is 123w I believe .
Since new nutes at .8 ec it seems to be at 6.1 ph and 420-430 today one day after . I see growth and my single tips that first showed after my round leads haven’t gotten worse plant seemed to perk up ?
room temp today was high 78 and so far low 69 56% humidity in room .
really quick question now that I added up after mixing nutes now that I am swinging and I want to close my gap back to 5.8 is it ok to use diluted ph down ? Or is it a no no ?

Thank you for the advice again and just to confirm it is ok to add ph’d downed water to my solution right now with me already having used ph up to my nutes when mixed a couple days ago ?My advice would be to add the ph adjustment to a gallon of water and add it to the bucket to bring the mutes down to the 300 range. I think you are running a bit hot
Starting with RO water is great. Potassium Silicate is a great option to stabilize PH and provide some buffering, and the plants need silica anyhow.
it takes a little experience to get it all tuned the way you want it, but it is worth the end result.
If I am starting with a clean res with RO water only, the silicate goes in first. Get to a stabile PH with a little time and stirring. Then the Cal Mag. Then adjust the PH to 5.8 using minimal adjustments. Easy to chase your tail up and down if you are heavy handed with the PH up. Then add in the nutes, stir, and come back in 1/2 hour to verify PH.
Once that silica is part of the mix, the PH will not swing as easily.
After you have done this about 10 times, it becomes muscle memory and it just seems to all work out.
I also recommend a nute level closer to 300 at this stage of the grow. The brown spots are because you are running a bit hot IMO. Also, now is the time to start considering if you are going to run biologics or sterile. I completely recommend that you do not run sterile. But it won't hurt too bad to stick with what you have this grow and read up on all that, just keep an eye on your roots. If they start to become discolored, post up pics and we'll get you fixed up.

Ok so I added some ph down to my ro water bout half ml to gallon then set it aside grabbed another unopened gallon and added 3/4 of the gallon to res . Water line had 3/4 inch of net pot being submerged . I took some pics of my set up . Not a full back picture but I’m ashamed I rushed to build this place in my garage it’s still somewhat not finished as far as wiring and I’m so ocd I wouldn’t even want to embarrass myself . . Anywho my new ppm was 350 and .7 ec . Ph atm is 6.0 I could add more of my ph’d down water but wanted to know your thoughts on my water line befor adjusting more ?Looking forward to the pics. I have multiple fallponics rdwc with co2 chillers ac dehey and humidifier with all kinds of light from 1000w hid to led to uvb tubes to uva to far red in all combinations. I’ve probably tried what you are thinking and can probably save you some time and money
I so wish my profession is HVAC so work always callsGot all the parts now you just gotta build the room.
Now would be a good time to get flu so you could stay home a couple weeks
