Just another newbie needing help

I will take some more pics tomorrow. There is some major curl now. I think I will raise the light a bit. There shouldn't be a nute lock up since I am regulating the ph... What a pain to go get distilled water though, plus that will add up to a lot of money by the time I harvest... I will have to test my tap water when I get the tds meter in. It is really hard getting a good picture with all that mylar. I've tried taking the flash off and leaving it on, just hard to get a good pic. But I will post one tomorrow. Thanks

RO water is an option. Reverse osmosis. Some setups don't cost that much. You hook it up to your house water line. It depends on how much you have to spend. I use distilled because I already had it. It's a bit of a pain always running a distiller. As soon as I get the bucks back up I will most likely change. I just changed from MH to HPS the light is 2 feet away and mine are staring to curl up more . I will get pic ,when I added the epson salt on my last res it stopped. I hope cal-mag gets here in the next day or two.

Ok, here are the latest pics. The curling is still happening. These plants are crazy bushy!! Is this good or not? It is taking up light from the other plants. Atleast compared to alot of other plant pics I've seen on here. I'm just still concerned about the curling of leaves. I still haven't got my ppm reader in. Anyways, here they are.
