Lower leaves browning

Alright. These baby's are two weeks old. All in 1 gallon containers with a 70/30 soil/perlite mix. Soil ph is 6.2 (tested 4 pots).

I'm assuming this is a water issue. I haven't fed any nutes yet, just two watering with 20% run off - last watering was 4 days ago (a few of them drooped right after watering - so I assumed I watered a bit too early). The soil is pretty dried out, but not bone dry when I pulled the one pot off.

I'm transplanting them into 3 gallon fabric containers soon. Assuming I've diagnosed properly, should this clear up the drainage/water issue? Or is there something else I need to do to help them recoup (calmag?)?



Thanks

Next transplant:
25% soil, 25% perlite ( large size), 25% castings, and 25% coir. Then add measured amounts of lime/ ground sea shells. Transplants are a great way to make corrections. I think you have no serious issues that transplant won't correct. Good luck!
