seedling emerged yellow---help this is my last seed

hi everyone I have a snowbud seedling that I germinated 3 days ago and this am when lights on I checked and I broke ground. Its in a grodan starter cube and Im using PH sensi grow as base with B-52. Spoke to advanced nutrients and they said it sounded like it was strugeling and give it some 1/4 strength with b-52. I did and it's still yellow. light is a full spectrum led 200 actual watts placed 22" above canopy. Temp 81-82....... RH ? probably less than 50%.... light is 24/7 as of today and intake/exhaust 190cfm 1.5min every 5 min. I will put up a picture for reference.

heres a picture. Notice the first set of seedling leaves are yellow with a pink/bronze tip. that's going on here I have never has a seedling emerge completely yellow. I thought they had a nutrient reserve when they emerge that covers them for the first few days until they set leaf. (at least in wool because its inert) PH is 5.5-5.7

Don't let it sit in a soggy cube or soil. Lots of seeds & seedlings are killed by to much water . Drop the big light and put a couple 6500K CFLs a couple inches away for the first week or so.

Edit: Just saw your picture and re-read your post. I thought it was three days old, but it surfaced today I see.

It looks fine to me, were you expecting fan leaves before sunset?

If anybody actually told you to put anything on an hours-old seedling, that person should be avoided in the future. He/She is an idiot

Thanks so much for the fast response. I did make sure to give the cube a lil shake if you will to remove excess water. I had to learn that the hard way after 7 seeds and everyone got R. solani. I think I should be a little more clear about my seedling panel. It has 2700k and 6500k main light with optional dominance in red and/or blue. And it is dimable, I have it plugged to a power stabilizer and then to a wattage meter so I can visually see where my wattage falls as the dial get turned down. I have always had excellent luck with seedlings and this light.

the led in the pic is my G8 450 full spectrum veg panel. That thing has way too much balls for a seedling. The seedling panel is a sunshine systems 300w ultra blend.

lol leaves before sunset hell yes!!!! no seriously tho I just have never had any emerge yellow with bronze tips. that's what alarmed me. and I know not so smart about the feed, however I have had ph swings with my wool and anticipated a P def so that was the real reason for putting a tad bit in the wool.....stabilize PH for good root development.

sorry to be a little overberring. I have been having the worst luck lately with seedlings. They always have too much water or a flipin PH issue and creates a P deficiencie and root growth sucks and I eventually lose them or get pissed off after 19 days of zero friggin growth I pull em out. I may have a lot of knowledge on cultivation but I am still very green and find myself making silly noob moves. Any and all help is greatly appreciated and will get +rep. Please help me learn the proper ways as I love this plant so incredibly much and growing to me is just a therapeutic as smoking.

Is no one here going to state the obvious?
Never give seedlings nutrients.
Especially ones that are just popping.
come on people,learn how to grow and handle seedlings.

Big bud thanks for sharring your input. Let me ask you what do you do when a 3 day old seedling is turning purple? stem, veins and leaves all purple. just give water?

It sounds to me like you've given it nutrient overload.
yes,I would give the seedling water only until it has at least three sets of leaves.
Do not rush things.
Take your time with it and it will grow and give you a good yield.
Peace

a couple pics of the seedling tent

time will tell. I give till tomorrow to show even the slightest improvement otherwise I have no need for a shity weak sprout. and 120ppm for a seedling in a totally inert media such as rockwool is not to much. 50-150ppm is exceptable. and the fertilizer is not true to its ppm reading due to the vitamins and humates, buffers and chelators that are in it. I just hope this one wont become a number pulled like the others lately. SMH..... and FYI the other received zero nuts and problems arose.

I stated exactly that in post #3

so from yesterdays post until now I have raised the light to encourage stretch. The plant did about a 1/4'' which tells me that it is not stunted from EC. Light has been lowered back to 21". Also because rockwool has a tendancy to raise in PH, I ran 6.0 PH 75ppm H20 to drop PH. First run was reading 6.8 so I shook out excess and re ran ending with 6.0 and 100ppm and then shook that out to semi dry the cube and prevent lack of 02. Slight purple hue still but Im sure that will work itself out with the wool being 6.0 I think she will be fine and is gonna take off when vigor returns.

I may even give it a watering in a few days of fulvic and humic acid. Probably around 40ppm of each to enhance metabolism

Someone did say it already^^^^AimAim^^^^ and noobs are here to learn, just like the rest of us did when we started, so if you're going to say it, say it constructively....but as was said never give babies nutrients until the lil round leaves ((cotyledons=food and energy for the youngling)) start to wilt and the tips of your leaves "start" to turn yellow...good luck man, you'll be fine...

No expert here but I have started using root riots for seeds and clones, and I'm sold on them. had a clone that I darn near fried (was digging the grave plot for it) flushed it out left it alone and she is out of intensive care and thriving. they work great you might want to get out of that rockwool. JMHO

Once again,no nutes for young seedlings.
You will burn it

wow get out of the wool. correct me if Im wrong please. U mean next time right. Its not cool to remove from wool after germination.

One more thing,I have never had any issues with my seedlings only getting water until about the third set of leaves.
You people are lucky that you haven't killed your seedlings or maybe some of you have but you don't want to admit it.
Peace
