Please have a look at these leafs! I gave a new dose nutrients by wormcasting rockdust and guano. Also some seashell chalk. I waited a bit, but it seems to continue spreading, at low pace.

It looks like potassium defficiency. If You are going the organic route, you can use a banana tea.

Could be nitrogen, but I would bet money that your runoff is too acidic so you have to flush just a little bit. Cheers!

Did you mix a shake or put directly into soil. There's alot of nitrogen in that mix. I'd flush and remove some of that build up.

Leaves losing "color"/turning yellow-ish. (autopot without nutes)
I've been using autopot system wihtout nutrients, plants now went to bloom. Could the smallest of the bunch (NorthenLight left down corner) have some defiency? As others are not "complaining", at least yet. Should purchase nutes that work with my autopot, only biobizz left now.

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Yellow lower leaves
Lower leaves are turning yellow. She just started her second week in flower. My first thought is I'm not feeding enough. She is short, but still a lot of plant here. Here upper leaves are a nice shade of green. She prays all day long. Is this a problem.

Is she too far gone or can she come back?
Week 8. Biobizz Light Mix, Biobizz Grow, Biobizz Bloom and Top Max (1ml/L up to 2ml/L). Ph 6.2-6.5. Leaves started yellowing just over a week ago so I started to feed with CalMag at 0.6ml/L. Some of the top leaves are starting to die and new growth is turning yellow quickly.

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.

Ph ? Nut ? Not sure what it is on the excess/defiency chart. Details below
What kind of issue here? I think about the pH. -Soil : Light-Mix Biobizz (pH 5,5- 6,5) -Water pH : approximately 5.5 / 6 (initialy 7.4 and I read that is too high, I reduce him to 5.5/6) -Watering : 50ml every 2 or 3 days -Temp and humidity : 23 celsius degree and 44% -Pot : 11L

Iron deficiency?
I suspect this is an iton deficiency due to excess phosphorus. Opinion? Im using GHE flors trio and added som Gro to make Gro Micro and Bloom in solution at a 1:1:1 ratio. Also added Cal Mend by Dutch Nutrients. Pic are 6 hours apart of new growth.

Northern lights with yellowing leaves
Hey Guys, my NL is starting to have some issues. I started off with the leaves just laying low, i've eliminated lack and excess water, and it's not temperature related. I did a small flush 3 days ago and things got worse. What do you guys think?

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.
