Hi, what is your PH? Clearly there is something wrong—-
It’s not uncommon for bottom leaves to die off as they get less light…. But the rust is most likely from PH. And the green you have going on looks really rich—- just based on color—- almost like too much nitrogen.
Run off numbers? If you cannot test for any of this, just feed the plant plain PHed water for a few days with run off.
Then make sure you have cal mag and the proper nutes for that cycle time

The heat can make a stem turn purple or red and if the damage is only on the top, your light could be too close.

Brown little spots on leavesHi, I went on vacation for 4 days, the ec went from 1.2 to 0.5 and many small dots appeared on a lot of leaves. Do you think it's due to that ? The ph went from 6.2 to 6.4 but I don't think that's it...
Thank you for your answer :D

Yellow leaves - moby dickThe olders leaves started to die and to turn this yellow-brown color.
I thought it could be the temperature (I am about to receive my temperature hydrometer to measure that), or over/less watering, or nutrients.
The plant looked great a week before.Week 4
