what def is this? cant figure it out.. pic of leaves

ive no idea what this is.. ive looked at every deficiency picture i can find and still im not sure so what is your initial thought after seeing this picture?

its from several plants but the deficiency is the same as they all recieve same nutrient mixture.

lookd like a P or K def...

really?.. they have been getting GHE 3 series at GHE's own recomended dosages.. anyone else support the P-K def?

Follow the basics for id

Stage of development
How old are you plants?
Veg or Flower?

Environment
temps Day/Night?
Rh day/Night?
Medium?
Ph?
Soil/soiless/hydro?
Feeding schedule?
EC levels of feed?
supplementing Co2?
training lst/fim????


I do not have a great deal of knowledge about various Def's but if you post the answers to these things some more experienced deficieny Experts may be able to help you more.

Totally agree with this guy! Had the same looking leaves on one of my plants in my last grow. Get some epsom salt from a drug store and mix 2 tsp per gal of water.

ok thanks alot guys, i was thinking this might be the problem but wanted to see if anyone agreed would have to order it on the web as they dont sell epsom here
