Issues with leaves

Hello, I am having a few issues with my plants. The leaves are getting yellow spots, the tips are getting hard, and the middle of the leaves are getting a bit mushy. The pH of the water is 5.8-5.9, the temp is a bit low in the room (around 60-75). I researched a bit and found that it could be mag defeciency, but sceptical. Does anyone have any suggestions. I am in the veg state with 24 hours of light using an aeroponic system (went from watering 24 hours to 15min intervals).

More information:
I am using Jungle Juice, General Organics Bio Root root booster, and Hygrozyme (roots were turning a bit brown so I used this and now they are getting better).

are you on RO water? looks like a calcium deficiency eitherway if its a mag or a cal def calmag will solve it

I am using distilled water. thank you for the suggestion.

yeah man distilled and RO water both lack calcium and you need to suppliment it once in a while. imo great looking plants nevertheless!

ah, thank you for the advice. You learn something new everyday.

Here is the setup I am using. It is not complete as I still need to beautify the cabinet.

hahahaha love it man. looks like a great use of space/lighting/ventilation.

Yes, this is only the veg area. The other side of the cabinet will be for flowering. I will be using a 400W MH light that I got from my place of work when they replaced the outer lights. I had to rewire the ballast and add more romex wiring to extend the light. Saved me a couple hundred bucks. The only thing I need to figure out is the temp issues associated with the MH light and light traps for the fans that will be installed. Growing marijuana is like raising a baby: you have to change it, talk to it, feed it, and get rid of the bugs when they get them....lol

U must use HPS warm light for flowering which
perfect on red lights and anothers

Yes, I know that HPS will give me the best results. Money is tight and I had to use what I had available to me at the time. I will upgrade to HPS when I get the money. The MH light and ballast was free so i couldn't complain....lol

What is the E.C and when was the last time you changed the res.

just changed my res like a week ago. I am not too sure what EC means. Sorry for being a noob....lol

You should check the ec or better known as ppms.
You could be under feeding nutrients?
You don't check your ph? The too is a
very strong possibility. You need to
check'em~

pH was at 6.2. I just corrected it to 5.7 so not a big change there. Just added some Epsom Salt today (5 teaspoons for 5 gallons) so hopefully i see some change. I need to get the calcium soon because the leaves are getting a bit worse.

Here a few pictures of my babies. They are looking a bit on the bad side. The leaves are getting weak in the center which is causing them to bow. One of my kids ripped the leaf of my "tomato" plant with a frisbee....lol. Now im looking at making a cage to protect my "tomato" plants.

I have done some maintenance to my plants. I just changed and cleaned the res. added 5 gallons of distilled water, used only 2/3 strength of nutes (jungle juice grow, bloom, and micro). Also addes Hygrozene, Cal/mag, and some root booster. Also added about 5ml of hydrogen peroxide (3%) to help the roots. The bottom leaf on one of the plants is looking bad (black mildew on the leaf) so I sprayed something on the plant to help with any diseases. The rest of my plants are looking better than the last time. Here are a few pictures of my babies.
