they are hydroponic, ph is 6.0 and i use pureblend pro grow for veg it is 3-2-4. the mg in it is .5%Do your nutes have mag in them? Need more info. PH, soil, etc.
it is a bubbleponics system 5 gall res. i just flushed a week ago today. and my roots have a slight yellow tinge and they look very healthy...They look like they have more issues then just mag to me, especially considering your nutes already have some in it.
What type of hydroponic system? How often do you empty the res? What color are the roots?
I ask because they have an overwatered look to them which means it is probably not as simple as a mag deficiency and it could be to much nutes or root rot or something.
and it is only on 3 fan leaves total over the whole plantit is a bubbleponics system 5 gall res. i just flushed a week ago today. and my roots have a slight yellow tinge and they look very healthy...
