Welcome to AFN Kingrat What soil/coco are you using and what nutes? do you know the Ph of your run off?
I would say they need CalMag and didnt get enougth N during grow maybe..But before doing anything let us know the info and we can help you out a little better. If you get time head over to the intros page :smokebuds:

Hi both thanks for comments will get to it! Spent absolute hours reading these forums on AFN full of great help and advice! I've got a 600*600 tent with a 180watt grownorthen 4 modular light. This think different was planted directly into john innes no. 2 compost. I have since bought 10l airpots which I will use for my next grow (dutch passion auto blueberry) which I will also mix with perlite. The nutes im using are sensi bloom part a and b. With big bud. I was late buying these and didnt use the grow nutes. This is probs why it had lack of nitrogen during early days. I dont have any means of testing ph at the minit. This is my first grow and am hopeful next one will be a lot better! I no I could do with spending some coin on more nutrients/additives and ph testers etc so any advice on what best to spend on would be great!!
 
It started its life under 150watt cfl for 3 weeks or so. I have also got to admit that It hasnt had a flush untill today! Learning and want to put things right for next one!
