First pic of bud I see some early reddening/browning of your pistols. Flower nutes are more potent than veg nutes. I would decrease your ec down to 1.8 1.9 max for flowering unless you really see serious yellowing of your leaves. Early colour change of your pistols is caused by to much nutes. They should stay white until the 5th 6th week into flower. Ph needs to be set at 6.2 to 6.3 for flower. Cheers

Browning leaves sections of leaf surface discoloured Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!

Thankfully not my plant but what do you think this deficiency is? My first thought was actually that one plant fungus r something that causes brown circle like spots. This is the top of the plant. No curling to leaves.

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Please check the last pictures I have posted. This is about a week after transplant, and the plant also has burnt tips. Are the brown spots from something other than transplanting into hot soil? They are in KIS water only soil and I have only been giving well water, ph is 6.8ish

Braune Flecken an den Blättern Hallo zusammen, Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel. Vielen Dank für eure tips!
