Plant Problems: Nute Burn? Light Burn?

Hey guys i have some dark yellow/orange spots on my fan leafs near the top of one of my mangos. Its only on this particular plant in my 8 plant flowering room. I go 3 waters with nutes then a flush then start it over again. The last time i watered with nutes was on saturday with its last cycle of nutes b4 i flush for the fourth watering with straight water. What does it look like nute burn??? Or something else. Thanx for the help guys....

Fox farm tiger bloom nutes

It does look pretty dark green, maybe back off to a 1/2 dose next feeding, but it looks more like a magnesium dif.

that appears to be a phosporus diffenciey,.....a magnesium diff,..would normally cause the leaves to go yellow ,...also im just asking but why are you flushing the plants so much,.....i dont think you it would help if not harm you plant stressing it out,...also you may wanna check your waters p.h that and your ppm's it may be locking your plant out from asorbing the nutrients i agree with the other guy tho,....you may wanna scale back on the nuter to 2/3 s strenth if not half....hope it helps!!

Yep, my mistake, your right about the phos.

same thing on my plants after i got my mg def corrected this followed and ime using all fox farm but urs is worse than mine

THANX FOR THE HELP. I DNT KNOW Y I FLUSH SO MUCH I GUESS I JUS FEEL LIKE SOMEHOW I WILL OVER NUTE THEM. IVE NEVER CHECKED THE PH IM STILL LEARNING BUT IT HASNT SEEMED LIKE IT HAS BEEN AFFECTING MY PLANTS IN THE PAST BUT I WILL DEFINITELY CHECK THE PH NOW. LAST WATER I PUT THE MAX THE FOX FARM SAID TO PUT WHICH WAS 3 TBL SPOONS PER GALLON(each water gradually adding more nuttes from half tbl spoon to my last water which was 3). NONE OF MY OTHER PLANTS SEEM TO HAVE THIS PROBLEM WILL STILL KEEP A LOOK OUT. I WILL CUT MY NUTTS BACK TO ONE AND A HALF TBL SPOONS FROM NOW ON. ANY OTHER RECOMMENDATIONS ON HOW TO FIX PHOSPHORUS DEFICIENCY??? GREATLY APPRECIATED THIS GUYS

yeah your waters p.h and ppm's (parts per millions) are the corner stones of growing along with lighting, nutrients and ventalation,......if your doing a soil grow it think the norm for most ppl
is around 6.5 to 6..8 you never wanna go above 7.0 or below 5.0 ..the ph is the scale that lets you know how hard or soft your water is and how well your plants roots will asorb nutrients in that water,....and your parts per millions is is the amount of nutrients that actually dissolve into the water you feeding your girls ,...if you mess up on other things you may be able to get away with it with minor effects on your mj,....but you gotta know your ph,...and ppms,bro...its a must!!
