Is it the nitrogen? If so what kind? I see 4 kinds.
Nitrate- Said to pass through the plant the easiest...and the easiest to pass through the soil.
Ammoniacal- Said to need to be converted to nitrate by microorganisms
Urea-Said to need to covert to ammoniacal then to nitrate.
Water insoluble- blood meal I think. Sprinkle it on the soil.

Is one of these the culprit?

The leaf burn is caused by giving too much of all of these, if you have nute burn you need to flush, and start out with a lower dose of nutes.

Obvious answer.

Using tap water with chlorine or chloramine will cause the leaf tips to burn.

so will excessive heat.

Point I think i'm trying to make is its best not to use products thats high in Urea while in bloom. If you give it enough in vegg, then all you should need are products that contain high nitrates or in lesser dosage ammonical nitrogen while in bloom. Regardless what most say, MJ still needs Nitrogen while blooming. The key is to control it.
