Deficiency or senescence?

My tap water has 130 mg/l of calcium based on analysis (conducibility 830 Microsiemens). So it's actually a lot. Does she need more calcium than that? Plus she is very slow, we are at the 13 week and was supposed to be cut last week according to the breeder ( northen light auto, RQS). Yes the temperature are night are 19 degrees. I guess some hues are caused by that. Because of some tip burns I didn't go with too much ease on adding nutrients. If I knew it would take so much on flowering I would have added more solid nutrients when I mixed the soil. So now it's only mineral fertilization. Thanks everyone

I was using like 30-40% suggested with living soil and it works great. Maybe ur a little too high so ease back on the nutes if you don’t have huge temp swings that could also explain the change. I amend w Gaia organic now and no issues.

cambiano colore in fioritura capita ogni tanto sopratutto quando tra notte e giorno c'è molta differenza di tempertura... invece vedo che hai avuto problemi di calcio le macchie marroni su alcune foglie
