I'm no expert, but what nutes are you using and how much?

Yeah looks like nute burn to me as well. I would back off the nutes maybe even hit it with just ph'd water for a watering then back on your scheduled nutes.

Am feeding coco a + b followin the guidelines on the bottle. I. Water about 1.5 ltr a night or sumtimes 2 I don't have a ph tester at the moment either

I never use more than half of what it says in the instructions on the bottles. and even by doing this I "managed" to burn them a bit.

How far are the lights from the plants? Ideally, the distance from the top of the plant to the light bulb should be between 12-18 inches away, this is the case for a 400w hps . Since you're using a 600 watt light, you may go a little farther than 18 inches or you can switch to a lower wattage light. By the way, are you using some exhaust fan to balance the temperature in your system? This is also important to regulate heat in the grow room. Also, burning of the leaves may be caused by the improper feeding of nutrients. So you can also check on that one. Good luck

This could be a "Nutrient Splash"...Which is where the grower is pouring his/her nutrient solution into the soil, and splashes some onto the leaves...But if its widespread then it could be anything.

you water every night?
