using nutes?

looks like you got some defficiencies goin.. potassium id say. were i yous i would flush it out. sometimes the potassium is there but is locked up by high salinity. then hit it with some nice NPK fert. you could also use some wood ash mixed up with water. but if you do be sure to PH it and lower the ph as it will probably be quite high.
