Some small insect damage.
However I agree and have come to believe that major insect damage may be the result of nutrient deficiencies.
My guess is the roots need more development, which itself also helps solve a lot of nutrient deficiency issues.
And they need a little epsom salt, both for the magnesium - which keeps the leaves nice and green and phototropic - and for the sulfur - which helps produce terpenes - which is one way in which weed protects itself against insect attack.
A little bloom food (0.2 EC to 0.4 EC maximum), a little epsom salt, and they should be fine.
And don't water too often. Roots grow better when the soil is a little dry.
