So i have mites but no clue what kind. Tried my best to record. I have predator mites on the way but neem oil and alcohol isnt working. Someone told me to try that but i think its just making them hide for a while then come back. This is my first grow so take it easy on me. I have been winging it. My humidity is 68% and temp is 78 i have 2 fans going (turned off/down for video) im still doing 18/6 and Ive been using fox farm soil and fertilizer. Any suggestions?? Or should I just want on the predatory mites to do the job? And most importantly what did i do wrong to make these little fucks come??

So im new to this. This is my first plant which is a clone of lemon layer cake. Ive been doing 18-6 with the lights and its in a 4x4 tent. Just got rid of mites (no clue which kind) but now im noticing even with the fertilizer (Fox farm big bloom) my leaves are so small compared to what i see when i research. What do i do? Or is this just part of the veg process
