Deficiency or Burn or both? pics

My Plants ( 2 HSO chemdog + 1 barneys blue shark) are 4 weeks old and it has been 3 weeks since I transplanted em into 3 gallon smart pots filled with Roots Organics Original soil + applied myco to their roots upon transplant. I've been watering only w/ distilled water except for two occasions where I watered with BAS 200x aloe vera powder. Average Temps have been 77-80 with RH 35-45. Under an HLG260 + hlg65 quantum boards @ 22-26" away. Liberal amount of venting/circulation. I also topped em last week and ever since they have grown very bushy. Anyway, new growth is showing yellowing at the tips and starting to yellow at the serrated edges. it also looks like some new leaves are going paler green in places + some look more green towards the tips/fingers. One of the plants also has white/pale leaf veins ..i've been also seeing purple petioles/purple stripes on some new stems..don't know if I should feed yet as I heard roots runs 'hot' .i have also noticed some 'clawing downwards at the tips' and darker green foliage on the blue shark/chemdog
thanks

Can you check a runoff EC/PPM? Forget pH checking it.

Feed a half strength feed if you can't and watch for a few days.

i unfortunately don't have a meter as of right now :/

thanks man will do

I would consider a little Mg...

update*

i fed them 1/2 tsp of roots organics uprising grow + 1/2tspfoundation + 2tbs ewc and 1/2tsp roots myco/beneficial oregonism topdressed 5 days ago, also watered w/ aloe vera powder two days ago..the rooms been at an avg rh of 32-38 % 76-79 degrees. I've recently noticed leaf curl on newer growth as well an overall 'droopy' look. the plants also seem stunted
Watering 1.5L/pot every three days

My experience with Roots is you get a 3 week charge max. It's not hot.
At 4 weeks you should be on a feed schedule already. Half strength.
Check to see if your nutes have sufficient cal/mag. Especially with distilled water.
Plants were topped so they slow down for a minute before they take off again.
PH your water.

yeah, I started feeding at the 3 week mark from transplant (they were 4 weeks old) ...I started feeding them roots' Uprising Foundation 2-1-1 and Uprising Grow 6-1-2 dry amendements as a topdress a week ago . Fed them twice so far, 1/2 tsp of grow and 1/2tsp of foundation each feed as recommended as well as some EWC + myco....
my original concern seems to be fixed but now they just seem lifeless and limp/droopy. they perk up upon watering but only stay perked for a day. I give them 1.5l about every three days. I can't see how this is a rootbound problem as i'm using smartpots.
***the bottom leaves are starting to yellow.

I tested soil PH (the test tubes/capsules) and it read 6.5-7

that looks to be the same problem I'm having! I'm also organic living soil, I gave mine a Lil dolomite lime, I'm hoping it does the trick!

I think you're drowning your plant

7 can cause lockout of micronutes incl. Mg. Above 7 definitely will.
