Please Help!!! Possible Calcium Magnesium deficiency or overload?

[Cogseye]

Plants are 4 weeks into flowering. Ph of soil and runoff in proper ranges. Starts at the top and moves down. Seems to only affect fan leaves for the most part. Any ideas?

 

[Nugg]

Any idea of ppm.room temps,rh,light hight,type of soil ect.?

 

[oldskol4evr]

gave um a pk boast right ?

Looks like they got really hot one day, or nute fried to me.....
Ok lets go with nutrient toxicity
Or hmmm...

Why are you spraying them?

Recalibrate your meters then do a slurry test and tell us the pH & ppm results

Oh, my. I did this recently to a new strain ( Lemongrass ) that really didn't like my CalMag habits. But I saw it in veg. The BlackJack was good with it, but in the Lemongrass it turned into a lock-up clusterfuck. I typically use 3-5ml/gal. but I think the real fuck up was using General Organics CaMg+ just once because it was on the shelf and I had run out of Botanicare. Lets just say these are two that don't run well together if you are too lazy to feed separately.

Sorry you are in flower. That's gonna stunt and hurt badly. It looks like multiple lockup to me.

Wasn't spraying I had just finished flushing the pots. A little dropped on the plant... PH after recalibration from slurry test was 6.7 PPM was 632.

They look like too much N to me.

Those numbers are acceptable so something else is wrong, what are you feeding and when you cut back on nitrogen?

 

[HeLLfiReZ]

To much calcium is my guess. I do things a little different than most. I use cal nitrate 15.5-0-0. With fertilizers. 0 to 7-x-x. Depending on the life cycle. Give me the ability to be in complete control of n.

 

[Beachwalker]

So I looked again they're definitely overfed (dark green) the Leaf curl is from too much nitrogen and I suspect you not really flushing out the soil well on a regular basis despite those numbers?

What kind of soil is it? Also am I seeing tons of little white dots have you checked for bugs tell us more what you have going on??

those numbers sound great actully ideal,but you didnt answer the question,did you give this plant a pk boast and seen it burning it like a flame and rush and flushed it?
ask me how i know the look,so you acheived the flush,now you washed every thing from your pot,you have to start over cause there nothing there as far as nutrients or microbe life, start feeding at 750 ppm and work your way up slowly,im thinking they should be at the 1000 ppm stage ,but work your way up,all those dead leaves need to go,doing nothing so to not attract bugs id cut um out

Agreed its going to stunt bud development quite a bit. If you can get your n under control you may have to flower a couple extra weeks. Even with the extra weeks you will still get less than optimal.

Never mix brands. Calcium and magnesium can be supplied by different compounds, and those compounds react differently with other compounds supplying NPK, in ways that can render the results insoluble to plants The chemists at each brand pick the mix that works within their line.
