stunted seedlings?

Hey bros, I have 4 Joey Weed Blueberry seedlings here on day 21 in promix bx and perlite.

I think I over watered when i first put the seed in the soil after they sprouted in paper towel.

Transplanted on day 10 but i think that was too early. In the process I might have shocked or stunted them.

1 of the 4 look good, the others not so much. Can I get some feedback from the experts here? Will #1 ever recover and will #2 and #3 be alright even though they dont like #4 but appear to still be growing.

Thanks! Here's the pics.



Seedling 1 - Leaves curling down, looks like it's barely hanging on.




Seedling 2 - Leaves aren't uniform / weird tips going in all different directions.




Seedling 3 - Discoloration in the leaves.




Seedling 4 - This one looks legit, I hope it's a female!

Looks to me like your standard mutations caused by the Blueberry genetics. They should grow out of it but will probably develop more slowly than you're used to with other strains.

Hooking is the growth of one side of the leaf or end faster than the other. Hooking sometimes occurs with zinc deficiency. This could be caused by the plants being rootbound, too cold, too high a ph, too much phosphorus, too much copper or iron, overwatered, lack of zinc...

Hooking and cupping of leaves sometimes occurs with calcium deficiency. This could be a lack of calcium, too much magnesium or potassium, lack of water flow from being overwatered, too low a ph, excess phosphorus with high ph, use of ammonia or urea nitrogen and not nitrate nitrogen (check your fert label for this :YaRight: ) ...

Check with distilled water the runoff of the cups ph. Full directions are in my signature below. This would be a good place to start to see if this is caused culturally rather than being a genetic mutation.

If tips or margins on the seedlings begin to turn brown, this would definately be calcium deficiency.

Props on the detailed explaination sproutco.

I got some ph test strips and I'll check the ph. Thing is, I got one good looking plant so far that received the same stuff as the other crappy looking plants.. shrug

With calcium deficiency:
New emerging leaves will have a torn appearance as the margins stick together, tearing the leaf along its margins as it expands

If you have one good plant and multiple bad ones possibly suffering from calcium deficiency, you have to consider things culturally that might be different. Its possible the good plant has a better root system and did better from too much overwatering. The others suffered. Calcium flows in the water supply from the roots so too much water or too little could slow this down. This might be an explanation. Check ph and other factors too. I have a strong suspicion that your ferts are mostly ammonia or urea nitrogen and not nitrate nitrogen = ammonia toxicity and calcium deficiency. Another source of ammonia might be the starter charge that is sprayed onto the soil before you buy it. This is a liquid fert to give new transplants a boost. With seedlings, you should probably apply alot of water before planting to wash/rinse the starter charge out of the soil.

I'll keep watering them and see how it goes from there.

There's 4 more little seedlings that are on day 5, so we'll see what up with those.

canine: After looking at one of those links with the mutant that flowered, I decided I'll keep the wack looking plant and hope it's a girl.
