Hey all I have two girls. Ones in a 5 gal, the other is my protein jug. Otherwise all the same. Ffof mixed with happy frog. I've fed only twice now. The first time they got some burn. But now they are both getting some yellowing while the smaller one is dropping leafs on the bottom which will be seen in my pictures. I imagine the roots are hitting the bottom and thats why the smaller one is getting rid of the lowers. However the bigger girl I don't know. Its the edges whereas she also got some nuts burn and some of her leafs almost look spotted with lighter green bumps. I have noticed some small holes which I believe is because my humidity is really bad I do not have a humidifier currently. First two are the smaller girl in the littler pot, the ones after the first 2 pictures are in a 5 gallon white bucket.
Don't be alarmed, when the lower leaves don't receive enough light, they die. Do you have drain holes in your DIY container?
I do, I drilled plenty of drain holes in both containers. I'm pretty new to growing legally. Hard to tell what is a deficiency and whats normal for me still. I love my plants lol
I'm not sure from just looking at that slight yellowing. I wouldn't worry about it either. That isn't magnesium deficiency, which shows up between the veins. It's too early to say if that is a K deficiency. Your plants don't look deficient at all. If anything, they may need the bottom branches snipped off so to encourage lateral growth.
