Brown Spots on Leafs

[tshirtlogic]

My plant is nearly 20 weeks old. I left it for the summer and when I came back it had little brown spots on the leaves. It was surrounded by the natural vegetation for the majority of the summer. Is this from lack of sun, disease or pests? Sorry I can't get pictures.

So you're baby is flowering right now. Without pics its difficult, but brown necrotic spots on fan leaves especially. The most likely cause is a Potassium nutrient deficiency. Wood ash in water is a good way to top up K. BTW, the brown necrotic spots will not go away...dead tissue is dead tissue, but if its a K problem then no new spots will reappear.

by wood ash do you mean ash tha tcomes from burnt wood? or is tha ta type of product

Yeah, I mean exactly that. Burned wood ash mixed in water will provide your plants with Potassium. I'm assuming you are growing in dirt...don't use in hydro.
