Brown Spots on Leaves

HomeGrown33started grow question a month ago

I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Look for calcium toxicity or nitrogen toxicity. If you use CaMg then you have toxicity not deficiency 100%. I cant see what fertilizers you use, however, my opinion, if you grow indoors in pots, i can see that you have good soil mix, you hardly have de deficiencies, only toxicities. If you dont use CaMg, maybe you use too much grow fertilizer that is reach in nitrogen and can be nitrogen toxicity.

Nitrogen toxicity, excessive N blocks calcium. Basically you are f@cked. If you want your weed to taste at least normall , stop heavy feedings, rethink what you do. Less is more in growing.

Hi, you are right with CalMag deficiency. Manganese is pretty uncommon and mostly only with trash fertilizer. Check the PH if she still can get the nutes if that is alright maybe increase you CalMag a bit. Also maybe check Runoff PH and EC/ppm. Hope this helps.

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.

What deficiency is this ?What is happening to my plant right now ? I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks. Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil. Started around 6th week

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?
