I suspect PH-fluctuation due cold temps at night. Lets see how they develop the next week. My second theory is, that the seramis i unfortunately put into the substrate, has lead to build up of salt. Ive read expanded clay accumulates them. 😖 Your thoughts?

You can use expanded clay as drainage and as mulch too without any problems, so it would suprise me if seramis would be a problem in your soil. Your plant looks like she was in autumn, so the could temps at night could be the problem. Check your PH level of your drain to verify if there is an PH lock or not

The plants look hungry in general. Which if feed level is not right the ph will go out of a favorable range. Testing your run off will give you a accurate reading of ph in substrate. They want a healthy diet of phosphorus and potassium in flowering to develop the colas. Flowering npk ratio is 1-2-3.
