Leaves in yellow

You are growing in coco which has zero nutrients, yet your diary shows that you are not feeding anything. Coco is basically "hydro in a potter" and you will need to start feeding from virtually day one. Your plant looks like it is starving or the pH is waay off and affecting nutrient uptake.

Definitions of azote. an obsolete name for nitrogen. type of: N, atomic number 7, nitrogen. You need to amend your medium with perlite to aid in aeration of the substrate. roots need air, some of the issues look like they are from overwatering in your diary on the earlier weeks, this plant does look a bit hungry but IDK what your feeding it, so it could be N it could also be PH or other issues. Coir also need to be buffered and have everything provided to it. Macros and Micros in its nutrient solution, also best to get some runoff to prevent salt buildup. Re: Coir buffering it means it needs to have Ca and Mg added into it, also every feed as the cation exchange sites eat it up and release extra Na and K, this happens when the coir starts to break down and its slowly doing that all the time. Better brands prebuffer the coir so this is less of an issue but cheep brands do not and they wash it with salt water in the ocean water where its harvested so its extra salty and has a high EC, Good Luck!
