Looks like she is lacking nitrogen. Its a mobile nutrient so the plant will start to use it from the bottom leaves first.
This can also happen naturally if the leaves are not getting enough light. The plant will drop its lower leaves to focus on new growth.
I would increase your Flores a little bit and see if the yellowing stops.
Good luck and Happy Growing.

Die bereits vergilbten BlĂ€tter werden in den meisten FĂ€llen nicht mehr grĂŒn. Sie erholen sich nicht und sterben ab.
Wichtig sind die jungen BlÀtter.
Diese schauen bei dir sehr gut aus. Soweit sich das auf den Bildern erkennen lĂ€sst. Die neuen und frischen Triebe erzĂ€hlen dir, dass sich deine Lady erholt hat đ€©đ

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?4y ago

Possible toxicity or deficiency?I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?3y ago

Yellow discoloration againI'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?3y ago
