Yellowing from the tips in usually means too much nutes. I'm not sure of the exact prob but best advice is give it a good flush. 3 times pot size of just ph'd water. Let it be for a day then start on the lower end of a full feeding making sure PH is right. The yellow leaves won't get better. Look at new growth for signs of recovery.


Also don't cut off the yellow leaves. If it is a deficiency the plant is scavenging nutrients its missing from the lower leaves to feed the upper.

Thanks, yeah I did a flush the other day.. maybe didn't do it quite right... still seem to be suffering... another thing I've been suspecting is could it be leaf septoria? Anyway getting some cal mag today, see if that's it...
