Super Skunk Auto Seedling in Bad Shape Help please

So Im doing an hydro setup for the first time... My ladies are still seedling so I jave them under 2 (2FT) T5s HO UNTIL I move them into my cabinet with 600W MH.

In rest are a little older.
Why is the are the coloylodon leaves turning yellow... The new growth looks mangled as well... Is something wrong with her? The next oldest has some brown spotting on the tips of the leaves... Whats going on there? The rest of these guys are taking a long time to pop there little heads out.
Should I put the oldest one in the cabinet to flourish?

Should I only be feeding kelp, pro bacteria, and root 66? No nutes really... Why is the oldest yellow and managled... Deficiency?

Do you know anything about hydro? It doesn't sound like it. What is your present EC or PPM? Base water PPM? What did you start at? Kelp is an additive and not a complete nutrient.

Check out Advanced Nutrients pH Perfect nutrients. No need to adjust pH and that is a real bonus. It sounds like it's on a water diet and starving

Always post pics and give basic information such as strain and the breeder, growing medium, water PPM and pH and all lighting.

SUPER Skunk Auto from Sensei seeds
Moved them under 600 WATT MH about 3ft away. No longer hand feeding hoping the roots chase the popping water bubbles.
Will spray very lightly the RRs in a couple days if they get 2 dry.
Base PPM of my tap water is 58 not sure of EC. Current PPM around 125.

These are autos and dont require much Nutes in the first 3 weeks. Cant assume its lack of nutes as the others are quite healthy.

Currently the Res Contains 11-12 Gals PH is 6.12
Hydroguard Bene Bacteria (Full Strength for 1 Week seedling)
Root 66 Root Stimulator (Half Strength)
Magic Cal (25 ML)

(No Boost, Grow, Bloom, or Thrive Alive Red/Green)

Thinking the yellowing seedling will probably die. And one is trying to recover from nute burn... Will watch closely if it gets worse I'll change the Res again. Hoping at least 3 out of the 4 will be viable plants. WENT THROUGH 20 SUPER SKUNK AUTO seeds to get them... I personally killed 2 but the rest never sprouted... Also I do know somethings about Hydro but I'm no expert. But I wouldnt sat I dont know anything I think you're making assumtions. Mayne my fault from lack if details.

Todays Pics... One of the ladies look a little droppy otherwise everything looks good (same)

One of the seedling look a little droopy otherwise things look good/same.
PH moved up to 6.3 which ia still acceptable. Sprayed the top of the RR of the droopy looking plant although maybe its slightly over watered but thw roots are out the pots ahoild be getting plent of oxygen.. Will keep an eye on it to make sure its ok.. What does wind burn look like im concerned the fan maybe blowing on thwm quite hard... Stems look strong though
Oldest still doing the V WING THING.. New growth looks green but stunted. But its a fighter...

They obviously need the PPM increased. Maybe change out the reservoir. I'm not an auto expert but they have to use nutrients from some source. Personally I start DWC around 350 PPM and increase to 450 within a week. With base water at 110 PPM. I use cal mag as part of the nutrients from the start. Adjust nitrogen from your Grow down accordingly

Decided to do some basic LST to the older seedlings also added an small humidifier. Have to refill every 10hrs or so... Added some plastic as humidity mist was getting blown away.
Roots are coming out of all net pots now. Some are even touching the water.
Will watch to see how they respond to the LST.
LADIES are looking healthy....

Yeah Im made some adjustment and they seem to be happy. Has grow. Alot in a couple days.
PPM 490(Still high) reduced PH to 5.9.
Root production has really taking off... Roots were kindabald before... They are really long some over 1ft...

Also added 2 2ft T5 HO supplemental lights as well. And frozen water bottle on the outside of help with both ambiment temps and added humidity...

Lots of new side brancing and leaves popping up in random places on each of the nodes..
Still cant seem to get the humidity over 45%
Also had a heat wave and my temps were up to 93 degrees. Saw some leafing cupping... Seemed short lived onced I cooled everything off hopefully no permanent damage notices some crumpled up on the youngest and even the stunted one (Which is was producing beautiful new grow) tooks some damage... My AC was off.for about am hour and the temps took off. My electric bill will be high. Can only turn AC off during off light hours.
Plant age varies from 21 to 18 days. So my PPM are a little high for autos... Havent noticed any adverse reaction. Other then they didnt seem to respond to high temps as well as when the PPMs were lower. 93 temps didnt cause cupping before. And the honestly dont look quite as "happy" No drooping of burning but I did see the edges look at little raised and crisscrossey slightly... Idk maybe its my imagination... Take a look at the pics...

Update...
Coming along nicely... 3 are about 2ft tall the other 1 is a little shorter

Getting there!

Had a couple low ph swings not really sure why. PH drops in low 4s. Didnt notice any adverse reactions. Adjusted to 5.5 hoping for up drift.

Defoilation and pruning continues as the buds develop. I removed most fan leaves. Especially if they had red stems. After week 3 of flowering the plants dont need them. This will maximize airflow and lights.

Buds still rather pisitlly no real solid buds... This auto was much talller and will take at least a month longer then the seller described.

Super Skunk Auto Week 8

If your leaves are fading from the bottom up you probably have a cal deficiency, I have been growing autos for a long time and it never ceases to amaze me the amount of stuff people do to there plants, me I keep it simple, I use ffoc + pearlite and wormcaseings, I only feed my plants base no food, I just want them to top and be in full flower, this usaly happens between day 50 and 60, at that time I flush out all the base, add flower base and agent and put plants under bloom light, my mean average from seed to chop is 72 days, what I'm trying to say and this is not advice but the more simple you keep things the better. Here is a pic of grapefruit just before I chopped, I keep things simple and usaly have no trouble, this site will not upload my pics sorry.

May have to chop early for stealth reasons....

Looking much better. Just ordered a scope but I think they are ready to chop...
