Nutrient deficiency or surplus?Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?6y ago

Leaf issuesHi all. I’ve seen some discolouration creep into some leaves on my fat banana over the past few days.
I’ve just ( in the last week ) changed from easy grow during veg to biobizz biobloom during veg with a drop of cal-mag.
The plant was damaged during LST so what’s the issue ?Week 5

White snipes on leaves... [ MAYBE THRIPS? SHOULD I USE POTASIUM SOAP? ]Hey guys! Do you think these are thrips?
The leaves have these white snipes already since some days ago.
Also, If you look carefully, there are micro white things on some parts in the leaves that could be the thrips themselves.
I'm thinking of adding potasium soap for this.Week 2

I'd like to know what happened to my plant but I'm unsure how to properly describe it. The photos in my diary should be able to make it more clean (W18). Maybe it was botrytis but I caught it on time? Or maybe something else? The trichomes got dark orange where all this happened!Week 18
