Yellowing leaf edges


#1

What is causing the yellowing?


#2

You look later in flower and the plant is eating it’s stored nitrogen. Hard to tell from the yellow light but looks normal for your stage.


#3

Could also be nute burn. Have you checked your run off PPM?


#4

Are you flushing?


#5

can u post some pics in normal ‘white’ light.?


#6

I haven’t but it’s because the soil I use doesn’t need much food. I do think it could be nute burn though because my ph meter wasn’t working right and I watered with 8.5+ water. Nute lock out. When I corrected the ph it took in what little nutes I did use. Its also ready for he est, so I guess couple of factors.


#7

I am flushing now.


#8

I will try to get some in white light. Thanks.
