Help please...
 

Ok tomato gurus my first transplanted seedlings are definitely having issues. What does this look like to y'all? I assume its the mix I made since the ones still in DE are looking great which you can see in the bottom pic. My mix is 50% peat and 25% each of vermiculite and DE.

Did you water them in with anything besides water? Mix in anything else, like ferts ?

Nope just water. I fertilized with diluted urin while in DE but not since transplanting.

looks like leaf tip burn. Not a disease but a symptom. Can be caused by fertilizing, over/under watering etc. They should recover. Lay off the fert and keep them moist, not wet.

You need to fertilize with something more consistent urine isnt.
It depends on how hydrated you are.
You aren't using vampire urine are you?:no:

Should I trim the damaged leaves off? The only reason I can think would be underwatering. I normally try to be stingy with the water to encourage them grow more roots after transplanting. Do you think the mix might be to acidic? Should I add some dolomite?

And Worth I don't usually fertilize after potting into a mix.

Just leave the leaves alone and as for watering you shouldn't under water you need to give them the water they need.
If the plant is getting what it needs the roots will grow just fine.

Yeah, its just odd. I never had an issue before. I will be sure to keep my babies watered good and hope for the best. Does under watering cause leaf curl as well?

might not be how much water they had but how much they can draw up. They looked pretty tight in the container before transplanting, were they grown together and difficult to get them apart without tearing the fine roots? They will recover but they need what leaf surface they have now to produce food. I would let them be. Next time if planting that dense I would transplant them sooner.

You need to use a liquid fertilizer after putting them into a potting mix with no fertilizer. Plants cannot live without nutrients and basic elements. They are going to need to eat just like us.

Yes they were planted very dense. They came apart as easily as usual. Maybe I should apply some fish emulsion?

I agree with Worth. Keep the mix moist but not wet and give them some time. Excess meddling causes more damage than always messing with them. Don't add any more fertilizer for a couple of days. Lay off the nitrogen for sure.

Ditto on the liquid ferts.
Did you ever grow anything in this peat before? I wondering if it might be too acidic and putting the plant into shock. You went from a near neutral PH medium to one that may be too acidic. Typically you need to add a little lime to balance the PH.

Ditto on not using or using ferts? As stated they haven't been fertilized since a few days before transplant. So 3 weeks tomorrow. The acidity of the peat does concern me and I bought some dolomite lime. How much should I use for a 18 gallon mix? I read the lime takes months to be available... Is that true?

I wouldn't jump into anything until I knew what the ph was.
maters can handle some pretty low ph.
