Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

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?

Leaves with yellow spots
We have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

Yellowing leaves on bottom and middle
I am growing in organic soil and transplanted 3.5 weeks ago from .75 gallon pot to 2.5 gallon pot. I noticed some yellowing on some of the leaves, generally towards the bottom but a little in the middle. Is this a cause for concern or do some leaves natural die off?

Deficiency help
What deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think. Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday). Do you think is this a problem? What can I do? Thank you. Peace
