Whats wrong with my leaves?I made several mistakes like;
- overfeeding with Cal-Mag
- Lightburn
- Physical Damage
- Algea in the pipe.
But can you diagnose what's the major issue? How can I prevent it?
Yet the yield looks quite good. I dont know what to think.Week 11

Yellow centre veins fan leavesYellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?3y ago

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before
Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer4y ago

Bottom leaves lifeless and yellowHi! My plants are in their 2nd week of flowering and some of the leaves at the bottom of the plant (very few in the middle) are starting to turn yellow and they look kind of lifeless. It's very dense in the tent so maybe they don't have enough light? or lack of nutrients ?5y ago

Looks like a defficiency. But how?Hi, I'm puzzled by this plant's behavior. It's being treated in the same way as others. And yet it's stunted and looks unhealthy.
Can you please help identify, what's happening?

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.Week 2
