I'd say there blotches on those leaves, mate.. get it sorted before it ruins a nice crop.
Could you give a few more details like medium used, lighting, nutes ect. it would help in finding out what the problem is with your plants.^^^^captain obvious. Lol
Why? Why do I need to add stuff when I'm using 3 part gh nutes? ?calmag im sure of it
Deficiencies can affect some parts of the plant first before it hits @ other places, like lower leaves progressing upwards & vice versa ect.I think maybe splash. Here's why...
They are in a homemade aero tub so the wholes aren't tight.
Only the bottom leaves that are close to the lid seem to be affected.
So if I had a deficiency or ph issue it would affect the whole plant right?
Ph is at 6.2 and has been between 5.9 and 6.4
