Help :(

Sorry for the bad photo, but does anybody know what this problem is? the plants have slowed right down in growth and getting pale-ing leaves and these brown spots...

grown in 100% perlite with a ph of 6.0 water temp 18.6c or 65.5f

Looks like might be a nutrient problem possibly. What are you using and how much?

Pretty sure ive found the problem, i wasnt giving them enough nutes

Normally it's the exact opposite - plants so young don't normally need nutes just yet
