Leaf Problems

Hi there fellow gardeners,

Using Auto pot system, Canna nutes' Ec of 1.5 Ph 5.7 600w x Sodium lamp in compost with a third of Vermiculite. Same as I all ways have and never had these problems which I hope you can help with. Take a look at these leaves! the whole plant is like it I have tried foliar feeding with Nitrogen and Magnesium but just dose not seem to help, the worst one is 4 weeks into flower the other 4 x weeks into veg the variety is "Big Bang Fem" any ideas will be well appreciated and thanks to all for looking and thanks for any help.

G3.....

The 2nd & 3rd look like nute. burn.... 1 & 4 maybe a deficiency from nute. lock out. 1000 ppm shouldn't be to high but,(maybe the compost had more N than usual) I'd flush go to half strength........ watch new growth. good luck

Thanks a Mill' sounds good, will put her in the bath later and give her a good old flushing through. Many Thanks G3

And hold off on the foliar with nitrogen also.

Thanks imchucky666, I will hold off with all the foliar feed and see after the flush. Many Thanks for the info'.....G3
