Hi @littlenugz, the curling and yellow spotting on pic 1 indicates calcium magnesium deficiency.

I see it the same way as nonick123 - they have a deficiency or blockage. Could be magnesium and iron.

Affected leaves should be removed, it will not harm the plant, it will quickly grow new ones.

You have some kind of deficiency.
Can you give us more details about the grow?

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Yellow/brown splodgesHi there
My plant is still young @ just over 2 weeks now. She has these brown/yellow splodges on only one leaflet but the new growth is looking a healthy green, so im not too concerned at this point. I am curious as to what it is though. What would you guys suggest it to be?

Yellow/ brown leaves #2 (pics didn’t post the 1st time)Hey guys so my plants are starting to turn this yellowish color and I’m not sure what the problem could be. Sorry for the second pic, it’s kinda blurry but that’s the actual color compared to the other leaves. It’s my first grow and I’m kinda lost on a solution . Many thanks

Leaves browning in multiple spots Lower leaves yellowing but have green veins.One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Black tips and spots on the leavesI'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Calcium / PH issues? Did I take the correct steps?Am I on the right track to remedy my plant's issues? Seems like calcium deficiency to me. Soil test comes in at just under 6.5, my reservoir water going in is 7.3ph, in case its actually a lack of calcium and not the PH i've top dressed gypsum (and epsom salts).
