Yes, there are drainage holes in the bottoms of the cups.
I've only got crappy pH testing equipment at the moment, which makes a proper runoff test very difficult to do, and I can't really afford a decent meter (I haven't got $150!). My Rapitest mini shows a pH of around 7 right now, some cups are closer to 7.5 and some closer to 6. I'd bought distilled water to use, but I guess I was too trusting.
As for the perlite, you're right Anony, I confused this soil with some old soil that I used before which did have perlite. Since I'm going to transplant in the next couple of days anyways, I'll just buy some perlite and mix up a better batch to transplant into.
I know that it was a bit early to add nutes, but the leaves were already yellowing even though the temperatures weren't very high.
I can't believe I forgot to check for pH twist! I'm really rusty. So my plan is a transplant in the next two days or so into soil mixed with perlite, which I'll test the pH of in advance. Then I'll adjust the pH using some pH down. Does that sound right?
