Dry leaves and purple stems

[The Elvis]

I'm with nammy... i dont see any "real" problems with your plants .. if they were mine id give them a dose of silica and a dose of cal mag.. even their lower leaves look OK ..

Thats the only issue i see but is not major cal mag and some silica will sort them.. Nice growing!!! Also mix in some molasses so the roots can pull up food better..

Thnx guys! The weather has been good here now and the ground for the plants got a bit dryer for a while now and they seem better.
Hoping for some sweed buds for when i can chop them down in about a month or so..
