need some advise with seedlings

ok guys, getting my grow going and have some questions about my seedlings. ill give full details so everything should be listed below.

barneys farm fem seeds
5 pineapple chunk
5 laughing budda

from my grow journal book

5/2 put all 10 seeds in warm tap h2o and placed in cupboard (all seeds sank)
5/3 put all 10 seeds in paper towel, then in tupperware (sealed) back in cupboard
5/5 put all 10 seeds in seed starter kit w/argo heat mat, humidome (vents closed), ph h2o, all 10 seeds popped, 6500k t8 bulbs (2/4') 24/7
5/6 some sprouts showing
5/7 removed starter plug, roots coming out of bottom. uppotted with light warrior, watered w/ph water, light still 24/7 1/2" from humidome, heat mat on
5/8 average 2" growth on 3 of each strain. moved light 6" above dome, heat mat on, watered, 24/7 light
5/10 3" average on all up-pots, new t8 bulbs 6500k, added more LW to pot, watered, 24/7 light
5/11 3.5" growth, 6500k lights, 18/6 light schedule. 1 LB sprout in seed starter (anout 3/4"). others are duds.
5/12 4" growth on all sprouts in up-pots, watered
5/13 4.5" growth on all up-potted sprouts.

water is ph'd to 6-6.5. i also have a water res (18 gallons of aerated h2o). light is dual 4' 6500k daylight T8 bulbs. light warrior soil, argo seed starter kit, dome, and heat mat. 5" clip type fan circulating air inside 4x4x7 secret jardin grow tent.

im wondering if i should up-pot to a 200mm pot (next step up) and bury some of the stem (about an inch) to give it stability. i had one stretching to the front this am, so i switched it around, and its back to stretching to the front. it might be my lights. also, looks like all 6 are stretching badly, even with the light only being 6" away. i have ONLY fed ph'd water (between 6-6.5), no nutes, ect. should i hit them with a very small dose of nutes, superthrive (superjive), or keep water only. also, would it be safe to toss them under my big 600w light and toss the flourescent? i wanna get these babies growing, and not look like im growing dandelions. lol i have a nute kit a company gave me to try. technafloura starter kit (from cutting to flower).


i really apreciate the help everyone. my old CG stopped by 5 days ago, but i really dont trust his judgement. he is still pissed i left him and im growing my own meds, even tho i found him a patient who buys more meds that i did.

the pot in the 2nd pic is the up-pot container in question i want to use. poor stretchy stems. kinda embarrassed. but im a newb, so some slack wohould be given. lol

What is your temp like? The plants too hot to me, and I would go with the 600w at around 3' above the plants and they should be fine. Still too young for food I would say, and definitely don't repot now, wait until you have a few sets of leaves. Good luck

thanks for the help!!

ambient basement temps are 65*, even inside tent. but remember, these seedlings are in a humidome, on a heat mat (non adjustable) on top of the seed starter tray, so temps inside humidomt will be higher. heat mat, tray is on a wood table top to keep off cold basement/tent floor. 1/2 of them have their 2nd set of true leaves. albeit very small. lol i read seedlings like about 80% r/h and moderately higher temps than plants.

durning tent testing/setup (12 hr run), tent temps are 77* max w/temp gauge 3' from light.

I am running some Pineapple Chunk's right now and every one of them is super stretchy I topped all of them. Its way too early to up pot those girls Like Jim said wait for a few sets of leaves otherwise you will just be watering a tiny plant in a huge pot and it becomes very easy to over water. I would not give them any nutes right now as your soil does have some in it so your good for a little while. How often are you watering? Those look kind of like some seedlings I misted way too much as a noob.

planning on LSTing them all. im running in FFLW soil, so there shouldnt be any nutes in the soil. How do you like running the PC? any issues, or other oddities that arose? they grow big, fast, slow?

the schedule i posted in 1st post was taken out of my grow journal. everyday with what i had done.


thanks

apreciate very much for the help.

I`m running 2 PC right now but 1 isn`t looking to good as of 2 days ago.




This is the one that isn`t doing well and I`d love some help or ideas as to what could be wrong

The plant in the second pic started doing what ever its doing about 6 days ago. She fell over and was lying down. I placed a little wood twig to hold her up but as of 2 days ago she is looking really sick to me.
I water twice a day. 2 hours after lights on and 2 hour before lights off.

could be over watering in the 2nd pic. what soil, other grow details? im about 4 weeks into flower with my PC's from seed. in the beginning I had some issues, then they just took off and haven't stopped growing. they love FIMing, supercropping, and lollipopping.

The soil is straight canna coco. I've been using a local shop brand veg nutes. The measurements on the bottles say 15ml per 3ltrs of water. I've been giving them approximately 2ltrs per day each. 1 ltr two hours after lights on and then another 1ltr two hours before lights off.
I'm thinking it's over feeding and watering.
I have just flushed both and will water/ feed every 2-3days and see what happens.

hi demon trich i wouldnt use the prop dome as they only for cuttings seedlings need good air

ive got a pineapple express bag seed going currently. she is in a red solo in FFLW and under a dome misted 2x daily w/6.5ph water. 4" already in a weeks time since popping. and under 600w 18/6 mh. ill remove the dome as soon as her first true set of leaves form.

That second one really looks like overwatering, coco shouldnt need watered daily, especially at that stage.
