A Case of Drooping Leaves

Hi all, first post, first grow. Day 16 since plant placed in netpot (put it in there way too early, what can I say, I was excited) and having some drooping issues as of late. Leaves still look healthy and growing, however things seem to have slowed a bit.

Details:
Single bucket rdwc w external res outside tent (5 gal + 5gal), 315 CMH, super silver haze from seed.

Res temp @ 62-70 started using HG a couple days ago
Ambient @ 70-80
Light height @ 36"
RH @ 50-60%
pH @ 5.6-6.1
Good airflow
Silica, GH trio, calmag combined for 350 ppm from RO water

Just did a res change the other day as it was time, and leaves had begun drooping. Went up from 240 ppm to 350 ppm as well. I lowered the light down to 26" the other day which I suppose could have created some stress, so strung it back up to 36".

Any ideas? Lots of opinions on the web for similar issues and would prefer to narrow it down before changing too many variables in desperation lol.

Pics attached, help is more than welcome.

How far below the netpot is the water level

Water is about 1.5", recommend backing it off a little further?

I have noticed quite a few threads saying it's over water / under air. I do have lots of air going into plant bucket as well as res

Too much light too quickly,water just at net pot.You should see new roots coming out the side of net pot in 24 hrs.If not something is very off.Temp,air,nutes.

New roots have been coming out consistently, and temp, air, nutes as stated. I suppose it's still shocked from the light as everything else is in the ballpark

Ya they were white prior to upping the dose of GH trio. That bottle of micro is pretty dark.

I guess try to rinse em off?

Figures with addition of hydroguard and res temps under 70, rot shouldn't be a problem. Will advise if I can rinse the brown off

Did the brown roots show up at the same time as the wilt?

No they started drooping when I dropped the light 10" in a day, turned this colour after nute change. There is a chance that I didnt notice them starting to brown prior however

Wondering why the long stringy root coming out the bottom,should be new roots coming out of ea little slot in net pot.Perhaps water level was to low for bubbles to hit net pot.

Hmm kinda weird,this is why i see two drain lines.Would rather see top feed,then only one drain.Pump is only heating your water but it does look small so maybe not a concern.

Ok so leave the two yellow drains,I would change the rez from pail to tote.15 G ish.Plant is going to get big!!
Change pump to top feed with 1/2 " line,T in res to bleed a little to make a waterfall..Then put that extra air stone in with the plant.Water flow between buckets doesnt need to be huge.

2 yellow lines, 1 is feed, 1 is drain, both 1". Not really an rdwc BC flow is so little, but it does circ.

Was going to setup a proper waterfall system w 2 Buckets on the next run like the 1 you mentioned. Think I should change it now.

Still unsure what my issue is

water level at net pot say 1/2" below,lots of air i like the 4"cylinder type,should see new growth of roots and plant in next 24hrs if not flush with plain water for 36 hrs .reload nutes at 3~400ppm after flush..
