Brown rust spots on oldest leaves
Brown 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?

Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

I have this symptom, a pattern of rust spots happening on new leaves, I have checked medium PH, which is around 7.5. I think it is Boron Deficiency caused by The medium PH not being approximately 6.5. I need more suggestions, What do you guys think?

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Foglie bruciate.
Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.
