I’d say it’s not toxicity, but I won’t pretend to know just by the pic, just that it’s not toxicity

Your leaves are a really nice shade of green, so i would say a slight deficiency, but if u are in flower its pulling nutrients from old leaves to new, so u could up your nutrients but its totally normal for that to happen. Good luck growing!

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

Newer leaves also turning yellow at the tips. Flush?
Newer leaves also turning yellow at the tips. Started to give the plant Terra Bloom,Sugar Royal, Pure Zym and power roots again after only giving it water for 2 weeks long. Is this a nutrient burn and will a big flush help it out? Doesn't a big flush overwater the plant?

Dry spots on Leaves
After repotting, my Serious 6 plants developed dry spots on the bottom leaves. What could be the issue here? Transferred to 15L Autopots with recycled substrate from my last grow (exchanged top layer)

Clones have yellow leaves. What should I do?
First time "Monster cropping" (A clone from a flowering plant) and they are rooting inside of humidity dome in a Rockwell cube, being sprayed to keep moist. The clones are yellowing, what should I do until they root?

Is the browning caused by nutrient burn or symptoms of something else? I had previously backed off, but want to know if I'm missing something. Most of the stems are red for leaves as well as petrioles. My runoff is around 900 each time @6.1. Only one plant of 2 has this.

Fine-Tuning Nitrogen Understanding (Deficiency or Toxicity) -- Suspected deficiency, so how do I adjust Fox Farm nutes? Increase ALL 3 nutes to 3/4 dose?
Initial inter-vein yellowing, followed by whole leaf yellowing. Minor leaf stem reddening. Older growth. Normal for flower stage (I believe), but too early for normal and rapid discoloration (week 6). This makes me believe it's a nitrogen deficiency, amplified by SLIGHT overwater

What’s your opinion on this one?
What you think about it? Is she getting too much? I’m not giving her too much in my opinion. Her stems are purple and the leaves are yellowing a bit. Watering always with ph 6,3-6,5. Thanks for your help! Happy growing!

I am on day 53, I know it’s normal for plants to yellow later in flower, mine turn yellow very early like week 7. Some people way later and theirs are still very green. I recalibrated my ph pen week 6. Happened in under feeding too. Makes bud look awful. What am I doing wrong??

Lighter green leaves
Day 11 bloom. Growth has been slowish I think due to compact soil, maybe PH issue. Using biotabs and light biobizz. Since switch, the leaves have turned much lighter green with few leave edges turning yellowish and can see more veins. Is this a feeding issue or other indication?
