Hi guys. OK so I came home last nite and there was water droplets on a couple of my plants (this was 45 mins after light had came back on and humidity is getting around 90 with light off) I dabbed them off with tissue and woke up this morning and this was on the plant that had the most water on. I fed them yesterday but gave the 2 pics the same. The 2 plants were the same yesterday apart from the one with marks was very very slightly brighter green than the other. Help please is it just where the water was on the plant or something more?
