White spots on leaves at 2 weeks

I'll tell you right now, it's NOT due to water droplets... not at all! If that was the case, the spots would be getting brown and crispy (although it's NOT a good idea to let water droplets sit on the leaves). What you've got is some kind of insect that sucks the life out of your plants.... and it doesn't matter whether it's aphids or spider mites or thrips or whiteflies... they all do the same damage and they all need to be gotten rid of. Grab yourself some Dr. Zymes Eliminator or some Spinosad and use as directed... you'll need to spray the tops and the bottoms of all leaves and it's best to do that just before lights out... Just another recommendation here - you need to be watering her a lot more... at her size, the entire pot needs to be watered, not just the small area around her... those roots are growing quickly and they won't grow well in dry soil so help them out by getting all of it wet when you give either water or nutes... the roots will grow out to get it! Looking good - and getting rid of the pests at this stage will be pretty easy... but you MUST get rid of them! Good luck!
