Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.

What do you think is wrong with this?
Just wondering if this is nute burn or something else. ... and what is it? I ph balance my water to 6.3, adding tiger bloom 10ml to 1 gal. Every other day. Just started big bud and bud candy @2.5ml per gal. Only feed once, yesterday. I left a one day gap between tiger bloom

Brown yellow leaves?
Can anyone help me? I had this issue with my last early Miss and thought it was a cal mag deficiency. I tried to adjust it last time during flower but it didn’t help. I really only notice it on one of them so far but I would like to fix the problem sooner than later.

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?

Do I have to worry?
Only on one leaf of one plant. Is this some fungus or virus? It looks a bit like coffee rust, but I couldn't find anything else like it. How should I proceed? Thanks in advance!

Color change.
I always get nervous when the leaves start to change. So my question is, this is natural right? I would guess they are a couple weeks away from finishing?

Carencia de Mg
Flag-shaped leaves with yellow spots, no doubt a deficiency of Mg. The problem is that I don't know what causes it. I will do a soil acidity test to be sure, but I'm leaving the thread open for more experienced growers in case they could lend me a hand with this.

Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.
