New grower: help! Seedlings falling over

[jnt62]

I searched the forums but I couldn't find anything that would fit my situation.

I germinated my OG Kush Autos in rock wool. they started popping 5 days ago. I had them in a propagator with/ Dome and heating pad. I immediately lower a 2' - 2 bulb T5 light close to the dome without touching it. The early sprouts stretched to the top of the dome by day 3. I had to remove the dome, still keeping the light as close as possible. I turned a fan on low to try and strengthen the stems.

The early ones still kept stretching. I assumed that they must be reaching for the light. Yesterday I removed the T5 and lowered a 600-watt full spectrum led to slow the stretch. I had to give the Rockwool a spray or two because they were drying faster than normal. ( I assume)

Today 2 seedlings feel over. I propped them up with toothpicks. I noticed that the main vein of the leaves and the second pair of true leaves seemed to be a little yellow. I raised the light about 6", but I don't know what the hell I'm doing!!!

I have a 1020 tray with 7" dome coming. What else can I do or look for?

Your time and help is much appreciated!

Transplant into your medium and when you do, cover the first inch or 2 of stem as well.

I thought I had another week. I'll have the system up in a couple of days. I'll just have to baby them until then.

Much Thanks

No water since yesterday and the yellow is 95% gone. I'm going to drain the H2O2 mix tonight. I should have the reservoir mixed and the seedlings in the buckets tomorrow.

Should I stay with 500ppm since they are still seedlings or bump it up some?

I still don't understand why the 1st ones to pop stretched so much. The two that popped late didn't stretch.

I finally plugged the girls into the system. I’ll give a brief(?) description of the system.

6, 2-gallon ebb & flow buckets, (Active~Aqua)

2 - 25-gallon reservoirs w/air-pump extra water pump for circulation

6" carbon filter with 450CFM in-line blower w/2-speed control

6 - 600-watt Full spectrum (not burple) LED grow=lights

2 Century timers. plugged into 2 dedicated a15amp lines

Hi jnt62 500 ppm is a little high for them right now I would lower it some and see how they do.

Hi, jnt62 500 ppm is a little high for them right now I would lower it some and see how they do.

Hey back at Ya

Thanks for chiming in! I germinated them in 500 ppm. I am at a little over 200 ppm in my res now that I have been given an education.

The girls seem to have taken to their new pot… well… all except one. It was one of the last to pop. It has received the exact same treatment as the others. It is even sharing a pot with the other late popper. I may have to cull it but I’ll wait for now.
Rather than try to describe the issue… here is a pic

She's looking worse. Any thoughts? The 8 others are looking healthy and most are larger with 2 nodes

To prevent stretch at early growth give plenty of light i mean full strength right from the start and they will not stretch as much and will have a stronger stem from the very start.I have seen people use a straw cut down one side.To put around them for support.Good luck they look great.

Thanks for your help. The more I learn the more I realize how much I don't know. Getting there with your help and the other kind people here. Thanks again!!

@TysonOG

Would you wait to start LST? Do you think SCRoG would be a better option for this OG Kush Auto?

Scrog is a better method for sativa dominant crosses indica tends to stay short and bushy on there own but its all up to you and i start topping some plants after second leaf set appear and lst start after the first topping.

I made an attempt to top 2 of them but I think I FIMed them. My plants are still very close to the hydroton. I want to start LST but I can't do it without the plants touching the hydroton.

Whatcha think... and be brutally honest. I hoped this grow would go smooth, but I knew I'd stumble some feeling around in the dark

I started LST the two I FIMed (edit)
