Its suposedly normal at week 7, but it might be lack of nitrogen, it may even be one of the reasons why it is so small.

Check your runoff pH. It should be between 6.3 and 6.5. If it's far off do a flush. Problem solved.

Yellow spots nute difficiency? Light burn?I noticed spots on both LB and NL that seem look like nute deficiency, my best guess is cal. I will check pH of soil runoff at next watering to eliminate lockout as a possibility. I've heard FFOF soil runs out in about 4 weeks, maybe that? Light burn from water drops on leaves?

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early

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?

1st grow yellow leaves and brown spots Last two days some big fan leaves started to get yellow with brown spots. Im half way through flowering stage. Is that normal? Can it be nutrient deficiencies if some of these leaves are on top?? It's not overwatering for sure, I'm puzzled :(
