Looks like toxicity. Bring your TDS ppms down to about 1000. Also looks like you have gone too hard on some of the bloom nutes. Other than that, I would discontinue anything that has a good amount of N in it. You're good though, fix this and they will be butes.

Spotted crisp leaves What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Calcium issues?Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Wilting leaves and copper spots? Save Me!These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Brown spots and patches I got some spots that look like cal-mag deficiency on 3/8 of my plants. I put some pics up that say "cal mag issue?" for reference. Not sure what this is especially when the others are looking happy. Let me know your thoughts <3

Leaves have some spots My auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.
