Water on leaves. In one picture leaves are soaked. Light is magnified by water drops and then cools leaves in spots it sits.

It could be from nutrients touching the leaves when fed.

Look like nutrients have spilled on your leaves, causing a burn.

Was haben meine Pflanzen?
Liebe Community, Neuling hier :) Ich habe zwei Critical Kush Auto in der 7ten Woche die seit der Blüte eine leichte Nekrose/Verfärbte Blätter haben. Leider habe ich vor 3 Tagen erst das erste mal mit Hesi Bloom gedüngt 5ml/L, vorher noch garnicht. Mehr Düngen? weniger Licht?

Crispy brown leaves
northern light is showing yellow and brown leaves at the top and the bottom of the plant. These leaves are thin and crispy like if they are about to fall off. I am watering it 2 to 3 times per week and started adding a bit of cal mag last week when they started showing brown dots

Deficiencies
Hey guys, First two pictures are from one plant and the third is from another. Any idea what the issues are? First two pics I’m thinking phosphorous? The markings are only in one section though. Second I’m thinking cal mag? Thanks everyone

Nutrition deficiency or nute solution on leaves during watering?
Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.

Carencia de Mg
Hojas en forma de bandera con manchas amarillas, sin dudas carencia de Mg, el problema es que no se que lo provoca, haré un estudio de acidez al suelo para estar seguro, pero dejo el hilo abierto a cultivadores más experimentados por si me podrían dar una mano con esto

Burn, deficiency or other?
I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.

Was ist das?
Meine Gorilla Skittlez (siehe Tagebuch) wird relativ hell und bekommt komische Flecken. Ich gieße abwechselnd mit Hesi Bloom (2,5ml/L) , 1ml/L Calmag und nur Calmag 1ml/L Dachte die Flecken kommen von zu wenig Calcium Magnesium. Jetzt steigt aber mein PH Wert von 6,8 auf 7,4.
