Could well be a potassium deficiency appearing or some lightburn as it is quite even and uniform.

Calcium and Nitrogen deficiency?
Hey guys, I noticed that on a few leaves have start appearing some rust spot. My guess is a calcium deficiency. What do you think? Also, there's a cola(the one marked in the pic) which has a slightly more light green leaves, nitrogen deficiency?

So... Been noticing last few days paler leaves overall - quickly. Might be paranoid, but thinking a nitrogen a deficiency - added tsp/gal Flora Micro 5-0-1 & PH water. The pale is subtle, but looking for greener pastures. What's plan B? Sorry for Double Post/Question!

Is this considered as pale green due to insufficient nitrogen?
This as a Cinderella Auto at day 34. I use mother earth's terracraft soil in a 2 gallon container. I feed her only Growth Technology Root Ultra from the beginning and add 0-5-4 tripart bloom for the last 2 feeding. Should I feed her nitrogen considering she is flowering?

Spots on leaves
One of my girls seems to have some spots on the leaves. She has been like that ever since sprouting. Is it just genetics or is it potentially a disease?

Leaves turning brown/purple
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one. What do you guys think ?

Today is the end of day 7 since she broke ground. I've been using distilled water and the ph seems good. I added 1.25 ml and now The ppm is at around 38 ppm. Are the tips of the new leaves supposed to be that light green or are they getting burned?
