Up your lights to 16 hrs/day. Bigger pots will help to insulate your young, tender roots from the low night temps too.
Personally I think using the condensate from a window air conditioner is not a good idea.
Would you fill a glass with it and be happy drinking it. NO.
It was not designed with that in mind. Who knows what treatment it has been subjected to.
Im just saying
I switched from tapwater to rainwater years ago because, over time, I found that salt build-up was affecting growth!At any rate, I've switched to tap water for now because I'm thinking there's a chloride deficiency.
From now on I'll treat condensate with chlorine bleach two days before I use it. I don't drink condensate nor rainwater.
Thank you. I tried only 6 lights placed 300mm (12 inches) from the leaves but it seemed it wasn't enough (too much stretching/bending). FWIW, I see no fading/bleaching/burning of the leaves with the lights as they are now.
Here are two pics of light placement...

it looks like these pots have accumulated a lot of salt, are the sides of your pots still white like the pics ?
if you're getting runoff with your feeds you should be ok regarding build up, they don't have long left, if they were mine i'd transplant them into a slightly bigger container, 6.5 litre if you can get em, just slightly dampen the topup soil, when you remove them from the salt catchers gently loosen the rootball before you transplant, get some air in em,goodluck, hope it works out.
