Light spots on upper leaves
So I noticed some light spotting/discolouration on the upper leaves of Samus. I've never seen anything like it before but is it normal or something to freak out about? Are the leaves mottling?

Burned or finishing early?
So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

Browning, curling of Green Crack leaves
Is this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Leaf damage/discolouration
The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Calcium or Phosphorus Deficiency?
One of my 3 Cream & Cheese has upper leaves on 3 stems/colas per the pic. The lower leaves are OK, the other 2 plants are fine. Thought calcium at first as phosphorus is more lower leaves? Maybe just add CalMag? Thank you so much!!

What is happening? (First Grow)
Is what I'm currently seeing nutrient burn due to low pH? If so, what can I do to fix a consistently low runoff pH (7.1 in 5.6 out)?

What are these yellow/brown dots and how can I prevent more from developing?
Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

5th Week Flowering Plant dying!
What is going on here? Started off as a Calcium deficiency so I upped the Cal/Mag, but the problem only seems to be getting worse. It only has 2-3 weeks left so I don't want to do anything too drastic. Any advice is appreciated!

Did I over-egg the nutes?
The leaves turned like this after a feed and a Mosquito Bits treatment, guessing I over-egged it with the nutes? Plants getting close to me cropping them, might leave them to dry out from their last water then chop.

Discoloration???
Noticing slight discoloration on Gelato, running in living soil, does this still have something to do with a nutrient deficiency? Has anyone encountered something like this?
