Could it be a nitrogen deficiency? Have you been feeding with a grow and bloom formula?

Magnesium deficiency, not a nitrogen deficiency for sure. could be too much calcium or potassium which restricts mag uptake. or just not enough mag. What are you feeding it exactly and in what amounts? whats the pH? Is your water source hard, or have higher than normal ppm's?

its also explains the leaf edges curling up

yes bloom and my ph 7 and im in a hard water area this is my first soil grow do you guys think they fucked or give em some mag

http://www.greenmanspage.com/guides/plant_abuse.html look under magnesium deficiency and its explain the cure. the pictures show more serious mg deficiencies that were fixed rather quickly

well if your water source is hard than it prolly has a lot of calcium in it. and lower the pH to 6. please be more specific. what brand of nutes. how much do you use per gallon of water?
