Hey guys,
I will try to keep a more frequent rhythm of photos, notes and comments during the week. I believe it is better to identify problems
The plant started to show some problems in its leaves. The low leaves began to yellow, get mottled, and twist. On uppermost leaves (new growth) scorched tips and edge burns. There is also some yellowing in top leaves. Unfortunately I can't say what caused the issue, if it was too much water or too much nutrients or too little nutrients. The water PH is always between 6-7 so I believe that is not the problem.
I took the opportunity to carry out another topping pruning and also an LST. Since my growbox is small I will try to branch as much as possible to improve my harvest. But first I need to identify and solve the cause of the problems in the leaves.
Oh, I can also say that it already has a slight smell coming from the plant!
Does anyone know what kind of nutrient problem is this?
The only thing I can say is: It is an immobile nutrient since it's appearing only on top leaves, and my fertilizers do not contain: Iron, Sulfur and Calcium.
The PH of the watering is always between 6 and 7.
Thanks
To me this looks like an excess of phosphorus locking out other nutrients such as calcium/magnesium. What is the total NPK value of the nutrient line in the ratios that you are using? If P is significantly higher than a typical 3-1-4 ratio then I would consider flushing 3-4x the medium with PH'd water and feed a modified schedule closer to the 3-1-4.
