Definitely a deficiency. I made the pics bigger because some of us are blind. HPS for too many years.

Do u know what it is I know plant cannibalism themselves at close to end of flowering any info would b appreciated thanks
Looks like calcium/magnesium deficiency. Many of my strains go this route later into flower. I just give them a dose of calmag every few feeds to keep them content. The plants will start essentially eating themselves though near the end. That's normal and common.

It is only normal if you allow it...plants can and do stay green and healthy up to chop.
Your plants look good, and I agree with speak...calcium def.

I prefer to let them digest themselves near the very end, and reduce the feedings to every other watering instead of every one.
No worries!

Deficiencies can be caused by overfeeding. You don't say what you've been feeding. You mention you've been giving Botanicare calmag. At 6 weeks into flowering I'm assuming you've been adding some bloom boosters and other additives. The best course of action might be to put less stuff on your plants. Base nutes at 50% for a couple waterings. People always think the solution is always to add something to fix it. Sometimes the solution is to take something away because there is already too much. Those leaves look healthy other than those spots.
Nutrient Antagonism
For instance. If you applied too much potassium which is in bloom enhancers in high concentrations you could lock out calcium and magnesium. Adding excess amounts of calcium and magnesium to correct the problem could end up locking out other elements and adding more of anything can send you chasing one thing to the next. The best thing to do might be to stop adding stuff and just use base nutrients at reduced strength for a period of time.
The best thing is to not overfeed to begin with and avoid these issues altogether.
Good luck.

Like I said. Too much. You're using three times the recommended amount of CalMag according to the instructions. And around twice the amount of Bloom Booster according to the Meig feeding chart. The only thing you should be using a tablespoon of is the Bloom.
Meig Bloom 0-7-3
1 tbl per gallon
Meig Big Tops "Bloom Booster" 1-4-3 1 tbl = 2x the required amount
7-10 ml .47-.67 tbl per gallon
CalMag instructions 2-0-0 1 tbl = 3x the required amount
Add 1 tsp (5ml) per gallon of water
You might have a deficiency but it's not caused by underfeeding, it's from overfeeding too much of certain elements. Nutrient Antagonism is real and is usually misdiagnosed and the standard solution is to add more to correct a deficiency. The problem with that is the deficiency was caused by feeding too much in the first place. The standard treatment of adding more usually ends up with a grower running in circles dumping this and that on their plants when adding less is actually what is needed.
