Leaf Tip Burn

I'm having an issue with leaf tip burn that progresses into yellowing blotchy leaves. any ideas would be appreciated. I'm thinking a deficiency of some kind but really have no clue. Thanks in advance.

What nutes are you using? give thema flush with ph'd water and then start using hydro nutes every watering.

I'm using FloraNova. I think I gave them to much right off the bat though so I cut it down to 1/2 strength. Also started monitoring the ph a little better. What PH is best?

When growing in soil, the soil and water supply should stay within the range of 6.5 to 7.0, in hydroponics the nutrient solution should stay within the range of 5.5 and 6.0.

I use Floranova exclusively, and use heavy feed schedules. What's your ground, and canopy temps? How much light you got? With the right Ph, enough air exchange, and plenty of light, at 75 degrees it's hard to nute burn even at 3 teaspoons a gallon once a week on Floranova. If it is true nute burn you probably have one of the aforementioned conditions at less than optimum.

I'm guessing pH is an issue as to nute usage.
