Week5

High Mousse, the cause for this deficiency is a nutrient lockout. You need to flush the soil to flush away the nutrient salts builded up inside your soil raising the pH and create a nutrient lockout. Solution, flush the pots with 2 times the pot volume in water with pH 6 and EC 1 will be enough for the flush. Let the soil dry out completely after. When the top 5 cm is completely dry you can give nutrients again like you did before. But this time water till 20% runoff to prevent nutrient salts building up inside the soil and prevent the EC and pH to raise because of this. Happy Growing my German friend! Greets from Amsterdam! 💚

Chlorosis is a condition in plants where the leaf tissue becomes pale or yellowish due to a lack of chlorophyll. Chlorophyll is the green pigment responsible for photosynthesis in plant leaves. Chlorosis can be caused by various factors, such as a deficiency of iron, manganese, or nitrogen in the soil, too much lime in the soil, or poor soil drainage. To avoid or treat chlorosis, it is important to check the soil for its nutrient content and, if necessary, add fertilizers or loosen the soil to achieve better drainage.

Defiantly a Magnesium deficiency. The reason being is the Interveinal Chlorosis happening with your leaves. That is the yellowing happening between the veins of the leaf. You can correct this by adding a cal/mag solution to your mix or by mixing up a magnesium sulfate powder. To mix up magnesium sulfate powder, one tablespoon per gallon of water. This will be immediately taken up by the plant. If you use a CalMag solution from a nutrient manufacture, follow the directions on the bottle. After a few applications you will notice a huge difference and stop seeing the interval chlorosis. Hope this helps.

Magnesium with potassium maybe. Lack of food or lockout in uptake , thats how it looks in general ...

Hello- You can add a little cal mag (maybe half strength of receommendation) but because your plant is in flower I think she is asking for some P and K nutrients. She needs some bloom food.
