`Leaf and tips on cucumbers seedlings are dry

Riverton, NJ(Zone 7a)

I started a few cucumbers to experiment their growth. They started out well but now the two main leaves are dry and more so on the tips and edge. My tomato plant has the same problem. Attached are pics.

Might try posting this question in the vegetable garden forum. This forum is not really for that topic. My guess would be over watering or over fertilization.

It's completely normal. The seed leaves yellow and die off as the true leaves develop.

Thanks for the reply. I read around the net and saw something about first set dropping. Just needed to confirm.

Why isn't that post appropriate in this forum?

Did you put any fertilizer on those cukes? If so, it's too soon, and you may be causing some damage. Hold off until after you harden them off, and plant them out in the garden...Just water for now...

Do you have the seedlings under lights and splash water on those leaves? That's a potential cause of those spots. I get 'em all the time on my tomato seedlings when they're close to the fluorescent lights and I splash up. Sort of like sun-scald...

I'm with you Linda. Good advise. I do fertilize my seedlings by adding just enough Miracle Grow to give the water a slight blue tinge. A little goes a long way.

Yes, you are in the right forum here besides, non subscribers can't access the Vegetable forum.

Welcome to DG ~ Deadhand!

Your plants are looking good. With the cotyledons ( or seed leaves) dying off (which is normal) your plants look healthy. As AltaGardener said "completely normal".

Like Linda mentioned, it could also be from watering your seedlings from above. Try to water them from the bottom to prevent leaf damage.

Welcome aboard!

Thank you all for the welcome and comments. I think a little water splash on leaves and a bit to close to lights is our answer. The tomato plant had a bit of leaf damage but is doing well now. I built a fan for my grow box that will help for any mold. Used a squirrel type fan from a old microwave oven. This is my first for starting from seed and looking forward to seeing my plants grow. The plants I am growing now are experiments. It would be a bit early for zone 7. My pics are the grow box, fan and timer controls.

WOW! Great job!

I was wondering if you always keep your seedlings sitting on a towel? or is that a temporary technique you used to draw off overwatering. If it is customary for you, you may be drawing off too much water from your plants.

Good eye, Steph!
I hadn't even noticed that towel!!!!

REMOVE THE TOWEL...Put your cells in a drip tray...
