leaf yellowing
Weedxczstarted grow question 2 years ago
I have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

Is your ph pen calibrated? It also looks like it is a lack of run off that is causing this. You have deficiency, and excess signs at the same time. Which is common in nute build up. Not sure what your growing in either. The salt build up will cause havoc on ph fast
GreenLover99answered grow question 2 years ago
Have you tested your water source? Is that ph reading with or without adjustments?
If water source is not the issue, check the calibration of your ph meter.
Is the medium new or reused? Could there be salt or other buildup from previous grows?
What are your watering practices? Thoroughly wet to run off and then allow top to dry before watering again. This will allow you to test the run off ph and may help you solve the problem.
Good luck!

Wilting leaves and copper spots? Save Me!These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Yellowing leafs and dying tipsHello !
In the last few days I founded that some leaf started to yellowing and burning on the tips .
Maybe it's all due to the flowering stage but I'll be more calm with your answers that are always interesting and helpful even if the platform allows only one to be selected.
