Yellow spots
I noticed some yellowing on some of my leaves. I did some research and think it may have been lead septoria. Not sure. Posting pictures... during defoliation I got rid of them anyway

Discolored Older Fan Leaf
I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?

YELLOWING IN DWC!
Recently a friend transplanted his Northern lights auto into a DWC set up, since then the plant has suffered severe yellowing and stunted growth. His nute feeds are optimal just as they were in his coco format and his PPM keeps decreasing. Any ideas?

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Ok see the pic of Jen above, compare weeks one and two. She came out of the ground like this, expressing pale new growth. Began walking back the feed PH from 6.8ish to 6.0 with meh results. Possible genetic? Seen plants "grow out" of this before but she still at it. Thanks folks

The lower leaves of some plants are yellow, then die. I'm very light with nutrients, there is no bugs into the grow room, what can it be ? pH between 6 and 7, lower it with few drops of lemon juice but bought a 3aciddown bottle. And are the buds supposed to be that big already ?

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.
