Intresting TPS seedling

[delito8]

I grew some of those tps seeds this spring that I got from wmontanez few years back. Other seedlings look very normal, but there is two seedlings with very narrow leaves! They don't look like potatoes at all.
Their pots are new and all other seedlings are just fine and these ones grow too, just a bit slower than the others so what could cause this?
I hope they survive, it would be interesting to see what they could produce.



What do you think?
