i agree, 1 the soil is to dense, needs perlite mixed in, and thats the first problem, the 2nd is a bug issue, i cant tell for sure but im guessing leaf miner of some sort, i do NOT believe you have thripes since there would be alot of silvery speckles/trails (the droppings of thripes) on the leaves, leaf miners eat trails in the leaves just like that wierd questionmark trail in the last pic. as someone said above Azamax, get some and do a soil drench treatment and a foliar spray to be doubly sure what ever buggers yah got are dead... no i know azamax is slightly expensive but believe me it is worth every single penny, i personaly had a HUGE HUGE war with Thripes, Fungus Gnats, Springtails AND Spider Mites about a year+ ago and i tried 4 other products plus a "home-made cure" and non worked, they did knock the populations down a bit but only Azamax compleatly annihilated all of the bugs i had in less then 3 days, after day 1 of soil drench and foliar spray with azamax i didnt see much of anything alive and after the 3rd day nothing at all and my plants started to bounce back from the damages caused by the bugs. again Azamax is worth every single penny.
