Help with deficiency identification

Pepe_Lapewstarted grow question 10mo ago

I'm having some type of deficiency that I don't feel comfortable identifying, cause lots look the same to me. Started on 2 leaves top cola about 1 week ago. The spot in the picture on the side and 1 more on top cola again showed up yesterday.

Too much nitrogen, not enough potassium and phosphorous......imo. Does not look like a calcium issue to me.

Familiaize yourself with a tool for this, such as KiS Organic's Dichotomous key for cannabis... it covers IPM and nutrient phenomenon

My opinion would be calcium deficiency, possibly combined with some magnesium issues – the brown spotting between the veins and near the leaf edges? Or salt build up and lockup of secondarys. Anyway you got a rather quick genetic. So perhaps don't mind and just push through the last ~2? weeks if it doesn't get too worse. Natural senescence is probably on the way or part of it. Much more important would you pls. check your canopy like NoVC01 said? It looks more than shady and some flowers are looking squished.

Try light burn. Have you forgotten to adjust your canopy.

Is this Nute Burn or Light stress? (hoping light stress)I've not fed in 5 days and this discolouration only started 2 days ago, I'm really thinking it's light stress, I've already turned off one of the lights instead of lifting the lights, more looking for reassurance I've DX'd the problem correctly :D
