Brown spots due to light height?

NamasteDazestarted grow question 4y ago

Brown spots on a few leaves close to the light that had yet to be super cropped to control height. Not noted on lower leaves. Temps/humidity OK, no changes in nutrients. Thinking this could be from being too close to the lights, but would appreciate some expert feedback. Thanks!

Looks to me like the start of a potassium deficiency. If it started on the lower canopy then calcium( which your not adding any cal-mag. Usually required unless you have really hard tap water. ) I rant into the same with my first grow doing a 1 grow :2 micro :3 bloom ratio for flower with general hydroponics. when it should be more like a 2:2:3(grow,micro,bloom) the Gro has a lot of potassium in it and most nitrogen comes from the micro. Stick with the feed chart for your ratio https://generalhydroponics.com/resources/flora-series-feedcharts/

Appreciate your insight and sharing past experience with this nutrient line. I am relieved to hear it is not a bug issue. Will add some additional grow into the mix..

Spots on plant? Is she sick and how can I help her?She has some spots and I'm worried for her. This plant is the only one in my tent like this, none of my others have spots. And I did transplant her to a 1 gallon pot, but she needed it. Her roots were growing out of the solo cup. Does anyone have any ideas what's wrong with her?

Strange Growth Does anyone have any tips or explanations on Kate and Randall's weird growth patterns throughout the grow so far? Kate has always had short fat stubby leaves. Randall has not grown a new fan leaf in what feels like a month. I think it was root bound before I repotted.

Zu viel Dünger benutzt?????I think I over-fertilized the plants. Should I wait until the drain and just water with plain water to get the excess under control, or should I react immediately and flush??? It's noticeable on the leaf edges, the tips are curling up, or am I wrong?

Normal leaves?Is this normal on young plants? Almost looks like trichs lol .. it isn't powder mildew is it? Also the leaf is weird wavy maybe after effect of the light damage caused by intensity? Again, my apologies for asking so much; I had considered myself very well informed on growing haha
