That looks like spider mites. Check the undersides of leaves for them.

Lower leafs getting yellow tips and spots I just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake. They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.

Yellowing leaves Lower leaves are turning yellow, these seem to be one that are hidden a bit from sight, so possibly not getting enough light, but it seems to be spreading, and one of them has fallen off. Is this some form of nutrient difficiency, or something simipler?

Yellowing, wilting, stunted growth Can anyone please help me identify whats wrong with them. I've done a flush, adjusted the lights, reduced the nutrient strength, I've pretty much done everything and still stunted growth and they are still looking weak and frail. I'm lost and I don't even know what's wrong.

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower The 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.
