If its a new leaf, its iron deficiency. if its near the top of the plant, its light burn, please let me know if its outside or inside?"

Yeah id not looked into this untill you mentioned it....i mean the smaller leaves around the developing buds are a nice darker green the bigger fan leaves are deffo getting the same effect all over

GsusKristOfTheBooda · Jul 20, 2020

Not the best shot but u can see the differation from how it varies across the plant

steve870 · Jul 20, 2020

Depends on three things: the medium you're using, the nutrients you're using, and the PPM of the tap water.

Please could you identify this leaf problem :)
