Spots on leaves, brown shimmering.
I've read that it's a boron deficiency, but I'd rather be sure.

Pest attack. What can I use to eradicate?
3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil? - The temperatures were very high here, exceeding 30°C, this week it will decrease. - I have other plants to harvest and I'm going to take advantage and clean the grow. Help 😥

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Overfed P and K
Unfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.

Is this really a potassium defiency? Any suggestions how to deal with it?
Hey Guys, need your help please. It's FD 28 and the leaves of my three White Widows show some signs of a nutrient deficiency (at least my assumption).I'm growing in living soil w/o any additional fertilizer and watering with a 7:3 mix of osmose/tap water and 0,5 ml/l CalMag.

How's the quality?
How would you rate the quality of these plants? The dark brown leaves have me self conscious of the roots situation. DIY supersoil mix recipe here: https://pastebin.com/pbxMZysq I've added more dolomite & guano as topdressing and fed liquid calmag and potassium during flowering.

Brown patches on leaves, thought it was calcium deficiency symptoms.
Having problems with brown patches, (see last 3 pics week 10), a quick google and I went with adding more CalMag but it's got worse the further into flowering I go, the farthest behind plant has least, furthest ahead is worst, any ideas?, many thanks in advance :)

Brownish Spots on 2 Older Leafs. Young plant.
I searched it up before posting this and what I found is: Leaf spot, canker, and fungus: Brown leaf spot, Yellow leaf spot, Cladosporium stem canker and Chaetomium fungus. Solutions I found in the comments below. What do you guys think? Can it be heat (a lot of hot days here)?
