Hi all,
My current grow is 5 weeks into flowering and one of the plants in particular is exhibiting leaves that are turning dark purple near the veins, and then eventually yellowing/drying out starting from the outside in. This is affecting the plant from the top down -- only the first few nodes are presently affected, but it keeps relentlessly affecting the next-lowest set of leaves.
I would normally just assume nute burn, flush and be done with it, but I have been feeding all of my other girls the same, using the same soil, etc., and it is only this one plant. This lady is by far the biggest and has the most budding sites of any of my plants, which made me think that perhaps it could be a deficiency instead of a burn ... ? Also, I have dealt with nute burn / lockout before, and it seems like this is a different color pattern. About two weeks after the first signs of darkening, the leaves start to get crispy and yellow, but none has actually "died" yet.
The pH is about 6.1 for all plants, which is lower than ideal, but not catastrophically low, right?
