Looks like natural leave colours to me, don’t worry too much just keep an eye on it. Leaves are prone to develop mutations

Rust-colored margins and dots. Potassium excess, Calcium excess, or something else?
I need your advice to get back to feeding. I kindly ask you to read my last comment (27/07) in the diary and take a look at the whole diary. I also uploaded a video. Thank you 🙏

What deficiency this is ?
Perhaps in these pictures you can see better, what deficiency this is, whether it is phosphorus, potassium, magnesium or zinc?.

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

Nutrient deficiency which kind and/or light burn?
Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

Help! Why are my leaves turning yellow?
Not sure why some of her leaves are yellowing on the edges. Is this due to environment? - 78.3°F | 64.8%RH Or a watering issue? - Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox). Or maybe a deficiency? - See Logs for complete details.

Add nutes or to much?
I don't know if it's a heat thing or a need more nutrient thing or too much nutrients. I have only added nutrients twice and it was measured out. I tested the soil with a cup of soil and five cups of distilled water the EC and PPM were almost non-existent

I had them in the terrace outdoors. Temperatures sometimes reach 40C. Lately more and more yellow leaves in the ABC have been showing up. In the other normal leafed plants crispy dried and brown leaves are showing. Now the ABC also is showing some dry leaves and yellow as well.

Did I do the right thing? Pls check my update on this week!
Can my Growmies check my update on this week please? Ppm shot up and I noticed nute burn. Weird bc I have only added water since last week. I cleaned the pump, removed air stone and lowered ppm. Definitely seems like too much nutes - hoping they’ll perk up.
