Yellow leaf spot, also known as leaf septoria, are caused by Septoria cannabis and S. neocannabina. These are fungal pathogens aimed specifically at marijuana plants. If its not budding then get an antifungal spray. Carfully remove all affected leaves and spray the rest. Clean up any fallen leaves right away.

You look like your having pH and pest problems. Start by checking for bugs as best as you can. After that make sure you pH balance your water and nutrients to 6.3
I would start there are check progress every few days. If things don't get better then your probably suffering from a major deficiency. Fixing the pH can get rid of false deficiency symptoms.

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own.
I’m not sure if it’s a nutrient deficiency or blockout from ph or something else.
I watered them only with water ph 6.5.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.
