Color change.
I always get nervous when the leaves start to change. So my question is, this is natural right? I would guess they are a couple weeks away from finishing?

help in Hydro RDWC/DWC
Hello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?

Brown leaves
Anybody know why it would sprout with the leaves looking brown/rotten? Does it have a chance of survival? I germinated in a napkin for 48 hours and then planted using tweezers. I use distilled water when I water

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

Too much light or other deficiency
Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!
10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

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.

I have a few brown spots and slight yellowing on a couple of my 3 finger leaves and even some on a 5 finger (#2). It seems to be getting worse every day. I have done a lot of research to find out what it could be but am very confused. Any ideas? Pictures from 2 different days.

Dry brittle leaves
Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?
