at first signs I thought this may be a heat issue but temps rarely go over 81.6,humidity is steady at 55-60% so thats been ruled out, ph is 6.7, only been using ph'd water no nutes,age just in there 3rd week, soil f&f ocen forest, the 2 plants in the pic's are the worst others show "slightly" the same as these 2. I'm kind of stumped as nutes have not been used yet but it looks like a nute problem to me? they were flushed a couple days btw... any thoughts On what to do?
