This is a nutrient burn and pH problems. I need some information about your feed and method, what growing medium?

I would say you either have mites or more likely a calcium deficiancy. Are you using calmag? Flip a leaf over and check for mites.

I would also say calcium deficiency if I didn't see burned tips of bud leaves, More likely calcium is locked out due to low pH, if he start feeding it calcium it might cause more problems. I would give it plain pHed water with 20% run-off, next watering start feed with 1/2 dose of nutrients.

Ahh, if hes not using calmag already he should be though. Theyre flowering. Calmag or some form of supplemental forms of the two elements should have been being added long ago. Those two are almost macro nutrient status in my books. They cause too many problems when theres not enough of them. And i really dont see harsh burn. When i see flower burn it usually causes sugar leaves to curl down and the edges of the leaves bronze and yellow until it takes the whole end of the leaf. The plants pretty all around green though. I see the tips are a little discolored but it doesnt look serious yet. I may be wrong, just my take on it. Its hard with no enviromental or feed rate specifics.

i agree with alien, need to hit with calmag some strains are whores for it

You are right, it's hard to make an accurate diagnose with out an information. I still would stick to my scenario, will see what the problem is when ill have some info.

If strain is not auto-flowering and you are not adding cal/mag to their feed, than these guys are right it's must be calcium, but I am still concerned about burned tips.

If you are adding cal/mag than it must be pH, 5.5 is a little low, raise it to 6. I would also reduce general PPM but increase cal/mag to 1/2. But that is just my personal view on this problem I am not 100% sure what it is. What nutrients and additives do you use?

Well sounds like you could bump it up. Could just be feeding off lots of it in flower with all the growth. And ya, ya might want to keep it in the calcium "sweet spot" as far as the ph goes just to make for optimal uptake. Id read up on calcium and see if there's any precursors responsible for aiding in calcium pick up.
