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.

Yellow leaf tips only on buds
Yellow leaf tips, only on buds... It is mostly buds nearer top, but some lower as well. It is not happening to fan leaves... This is an auto, around day 60 (4 weeks of flower). I have stopped giving nutes for over a week already to deal w nute burn. But this yellowing continues!

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?

Leaf Discolouration
I notice some leaves developing this yellow discoloration on the older growth, usually closer to the central stalk than the outside. The green gradually shifts to yellow going from mid leaf outward to the tip. I'm hoping it's just lack of sunlight from the dense foliage. Ideas?

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Leaf Diagnosis Needed
I need help. Leaves are turning yellow at top of plant only. And only on American Pie. Not Northern Lights. I am using a Sonlipo SPC2500. Bloom mode. Is it possible to have lower ppfd levels and still get light burn? Thanks in advance.

About plants ..
For those who have dealt with nitrogen deficiency, after correcting it, did the affected leaves regain their color, or did they stay the same while only overall plant health improved?

Yellowing leaves.
Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Advise to flush or feed in Veg
Does this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Identifying the cause of stress
Does anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?
