This is my first grow and I'm not sure what's going on but I'm beginning to get some brown spots on the leafs without and indication of yellowing along with small bumps that eventually kill the leaf. Here's the grow: Pineapple Punch autos Outdoors in a warm climate 75f-85f Soil is: 60% Fox Farm Ocean Forest 20% Perlite and 20% Wormcastings Watering comes from collected rain water and I've added no extra nutrients. The plants are just over a month old. Thanks for the help!
Looks to be a potassium deficiency to me. If you have nutes feed next watering or give it some fertz that are high in potassium.
Ok so I've tried feeding with Fox Farm grow big every other watering and it doesn't seem to be helping. Here's some photos of it worsening.
Check out my old post " Yellow tips " a kind gc member posted an informative list of the different deficiencies, what they do to the plant, and how to correct. There may or may not be something helpful there for ya. Good luck.
