Spatz you have found my problem.
Same thing was happening here with the babies. I'm about two three weeks behind you but I could tell something was wrong with them. I didn't loose any plants but they were not looking to flash.
I pulled one out of its pot and the poor thing was drowning
So I transformed the deck into an ER and perform a swift apologetic transplant into new pots and mix. They are resting now and are looking thankful.
Lomatia, you might just see me and Spatz rock up at your Marysville seedling sale. Nahhhh I think we should be alright.
I finished the Self Watering Test Tub and will post pictures tomorrow. Looks pretty good I must say.
*anxious mum*
