Hi everyone,

I'm having some problems with my plants. Some of the leaves have turned yellow and some have some brown spots on them.

I feed them today with some bloom and fish mix. They're currently 7 weeks in.

Does anyone know what it could be?

Thanks

What type of soil are you in? All that yellowing would lead me to believe nitrogen deficiency. Usually won’t see that much yellowing until the plant is nearing its life cycle.

Just using Jack's Magic Multipurpose soil. I've given a double dose of Fishmix today. Is there anything else I can do to fix the problem? What about Cal-mag?

calmag is not so common for soil grow, although its possible. N deficiency is my bet tbh, and not only, they need nutes man, and yes, its a bit too late imo, since the flowering occur. veg nutes are required for at least 2 weeks into flowering, to avoid the yellow leaves at that point, but you can still get decent crop i believe
