Brown yellow spots

Hey, you are correct. She is getting too much heat and the water can’t get to the leaves fast enough so they burn up. Maybe try putting an extra fan in to get those temps down a bit. The calmag helps too with the stress the girls are on from the heat. Happy growing

Definitely a calmag issue but also looks like she's begging for more phosphorus. Whenever I see more than one nutrient issue simultaneously, I always assume you have a pH problem which is limiting the nutes that the plant can take in. It is always possible you just slipped up on multiple nutes when making your feed, but definitely check pH and calibrate your meter before doing anything else. Good luck!

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.Leaves. Color - Pale

I water my plants everyday , however I have mixed my nutrients “ph perfect grow, micro, and bloom” in with my water only the appropriate amount given on the bottle. Should I be using water with the nutrients everytime I water or switch it up with plain water as well?Week 2

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight6y ago

Brown rust spots on oldest leavesBrown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?9mo ago

Bruising or nute problem?I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.5y ago
