Soil? Hydro? What light? What are you feeding them? etc. I'm a new grower myself, but somebody once told me, "if it starts from the top its overdose, if from the bottom - deficiency"

Maybe magnesium or zinc. If start at the top zinc if start at the middle of plant mag. You need to post more info because nobody can help you. Actually I noticed not much peoples in forums like to support noobs.

OP think of your plants problem like a crime scene. The people you're asking for help are the detectives and you are the only witness to the crime. You need to give the detectives every last possible shred of information that may even be somewhat relevant if you want the problem solved. The less evidence the detectives have, the harder it is to solve the crime and the more likely that it goes unsolved.

edit: Realized I probably should have been specific about the information the detectives are looking for.

OP I saw you mentioned a couple things that help like 600w hps, soil and your nute brand but something like this is probably a good point to start if you want help diagnosing something real accurately:

Environment (Temperature/humidity/air movement)
Genetics (Strain, indica or sativa/etc.) -
Medium (soil/rockwool/etc.) -
Lighting setup (schedule/# of watts/etc.) -
Feed and Water (source/schedule/quantity/frequency/etc.) -

it's an iron deficeincy.. give them some cal/mag with iron in it.
adjust your PH to 6.3 to 6.5....

Soil? Hydro? What light? What are you feeding them? etc. I'm a new grower myself, but somebody once told me, "if it starts from the top its overdose, if from the bottom - deficiency"

Maybe magnesium or zinc. If start at the top zinc if start at the middle of plant mag. You need to post more info because nobody can help you. Actually I noticed not much peoples in forums like to support noobs.

If the deficiency starts at the bottom it's a mobile nutrient...example: (N,P,K,Mg) are mobile.
If it starts at the top it's a immobile nutrient...example: (Ca. S, Fe) are not mobile..
If the leaf curls and or turns brown and dies quickly its most likely a nutrient burn...or a PH problem..




hope this helps!

Iron starts more at the inner of the leaves and progress to tips. This def looks like strart at the tips and moves inner. But pics of whole plant will help without hps. Anyway spray with epsom contain mag and iron you will know after one day or two.
