Looks like calcium def. to me . RB
Chicken is correct. Can you get a PH reading of your nutes goin in and then take a reading of the run-off. Soil,coco, hydro? I am going to try to post a couple of pics .
Pic. 1 is Magnesium deficient
Pic. 2 is Calcium Deficient
I would like to see a pic of the overall plant. Is it just one or two plants that are affected or is it most of them?
bses to eror on the side of caution. If you use treated water , you will def need calmag suplements. Is this the first time it has happened to you? Anyway, my money is on cal/mag def. I read a thread once from a reputable grow guru that stated 90% of nute def are cal mag.
Good luck
Hey bro i recently had the same troubles w/one strain i was flowering.Heres a couple things i found out that might help you fix your little problem.You can treat by foliar feeding w/1 tsp. dolomite lime or garden lime per quart or you can take crushed up dolomite lime or garden lime in a gallon of water and water it through the medium.1-2 tsp. per gallon which is slow-acting,garden gypsum which is medium absorption or limestone which is medium absorption,rock phosphate which is slow/medium absorption.Calcium is best absorbed in hydro/soil less mediums at ph of 5.4-5.8 the best range for hydro and soil less mediums is 5.0-6.0 anything out of those ranges will contribute to a calcium def.Mag. is best absorbed in a hydro/soil less medium @ ph levels of 5.8-7 and gets locked out of hydro mediums @ ph levels of 2.0-5.7.Nutes that have Mag. in them are epsom salts which are fast absorption,dolomite lime/garden lime which is slow absorption.Sulfate of potash,magnesia which ismedium absorption and worm castings/crab shell which is slow absorption.Earth juice microblast which is fast acting and has alot of secondary nutes.I hope this can help you alittle i got all the info out of my guide to sick plants from planet ganja.It helped me out alot!!
Did you try lowering your water/nutes ph to say 6.0-6.2? There might be calcium there, but if that ph is a little high it can stop being absorbed in the plant. Just a thought bro. ROOT
edit: sorry , I just read your ph is 6.2. Is this soil?
