HELP:Pictures of my deficiency problem !!!!!!!!

[coopdevillan]

I have had these mums for maybe 2 months now. They came from healthy clones from my Herijuana and Basic Beer grow. I am useing Techna Flora 3 steps nutes. My ph floats between 5.5-6.2 PPM is 1130. I run rockwool coverd in hydroton all pretty much washed through and used well. Top feed drip 3 times a day for 15 min. These strains have all been through this before, meaning Ive grown this method last round pretty much and was cool. Only difference this round is I use a lower strength solution because of the smaller plants Im keeping. Sooo if this is a lack of nute I can see, but burn Im not so sure BUUUT is possible ?

Please help its kind of progressed in a short time ?

Your ppm might be to high causing nute lockout. I'd flush them real well and lower pp
to 900
