does the leaf feel leathery? It was probably under watered or over watered at one point and the ph was slightly off. Nothing to worry about if it's just the bottom fan leaf. Just re adjust next time and you will be fine.

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

Deficiency issue/problem with leaves
Any idea what problem I’m having with my plant/leaves? I’m guessing some type of deficiency because I’ve only fed once and it was a few weeks ago. (Check photos in most recent week). Any advice/ tips would be awesome, thanks!

K deficiency? Or something else?
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

Brown area on leaves
Hello everyone. Some leaves on my plant are getting brown spots. I gave GHE essential (trace elements) and cal magnifique (0.3ml/L) this morning, as well as biographie Bloom. I’m thinking it might be a magnesium deficiency, what do you think?

Emerging Issues - Week 9
At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.
Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

2 out of 5 plants are showing signs of nutrient burn? Soil grow
Hi, I am seeing clear signs of nutrient burn but only on 2 out of 5 plants. I feed them organic nutrients, following the chart that was provided by BioBizz. Why are they still showing burned leaves? I watered them thoroughly until the runoff was clear. But leaves keep burning.😦
