3 Chems By Top Dawg

Hi all. Is it toxicity or deficiency? I feed them canna a+b, rhizo, canazym and boost at 1.6EC and plain phed water every other watering. They are 5 weeks since flip. Dimlux 1000w expert series 440v DE @600w about 3 foot from canopy

Looks like a toxicity. The leather like leaves and darker tint indicates too high ec as well as burnt tips. Try backing down ec now that your in week 5 and give a good flush one time a pre flush if you would with correct ph for your medium and low level nutes
