nirvana blue mystic autos

in canna terra pro,1st time with auto,s,didnt add any nitrogen as recommended by canna.just started giving half strength pk13-14 and i dont know whats going wrong. could someone advise me before it all goes tits up plzzz?
ph 6.5 all nutes and soil stable at 6.5.some of the leaves are deformed aswell!!!!

its a nutrient burn. Not gonna talk out my ass and say which one but if your only using Potassium and phosphorus then its a p or k overdose imo.
