Can someone help address this issue im having with the leaf spotting on my plants

[tsboss1]

Hello, I am having some sort of spotting on all of my agent orange plants thats in veg....Dont have any idea what this is. I am doing a hempy grow (oc+,perlite) and the temps have been in the high 70s, in a grow tent. I have a 600 watt air cooled light set up and the last watering I gave them 2 tsp. grow big FF, and 3 tbsp big bloom....

Thanks

My vote would be related to PH issues, do you happen to know what yours is?

Try a marijuana related search on google involving white spots + ph, it may give you some insight.

Cheers,
