looks like it might have a zinc deficiency maybe.

should i add lime to my pots is it ok to just put ontop and how much should i put on???

i think its a magnesium/calcium defficiency, my greencrack plants started to look kinda like that, added some MagiCal, and it pretty much fixed'em up

I would add some lime and Epsom salts, both are easily obtainable from your local stores.

I use 7.5ml of lime/28oz or 15ml/gal and for the Epson salts (Magnesium Sulfate) I use 1TBS/GAL or 1 TSPS/28oz

I had some yellow(burning) on my leaves as well.

Think your ph is off.

Also it reminds me of what a plant looks like that's getting too much light and heat.

good luck
