Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

Am I taking the correct steps?
I think this is due to a combination of overwatering (1l per 24 h in 60% Light-Mix, 30% coco, 10% perlite) and possibly overfeeding (used close to recommended dosage). I have let her dry out for almost 2 days and today watered 0.5 l plain water ph-ed to 6.5. What do you think?

Yellowing fan leaves
Larger, older fan leaves turning yellow slowly. Rest of plant still doing great. Also, leaves are reaching for the light. Is this due to maturity? Or might something else be going on?

Leaves discolouration
I have noticed that a couple of leaves on 2 of the plants are getting yellow spots, the only thing I’ve done differently was that I gave the only plain water without nutrients for 2 days, anyone knows what could it be ? Thanks

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔

The tips of the leaves turn yellow
The tips of the leaves turn yellow. I don't know how to identify the problem, is it the mycorrhizae that make them hungrier? Or do they just have too many nutrients?

Possible calcium def. or other issue affecting leaves and buds
Is this a calcium issue, and if so why is it spreading to this one bud in particular? There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

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.

Nute burn or something else?
My middle and top leaves are yellowing from the tip and edge inward, is this the nutrient burn or another issue altogether? Runoff PH was 5.9 and ppm was 700.

Yellow edge with brown spots on fan leaves
I am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Yellowing leaves on autoflower dwarf
I'm 12 weeks of vegetative growth deep with an auto-flowering dwarf strain. My plant is nearly 1.5m tall, showing no sign of flowering but I'm starting to get a number of yellow leaves lower down the plant. What is causing this? Should I leave or remove them?

Weird burn
Thought I had a calcium deficiency but now I’m not so sure. Could have got a bit too much direct sun out of the tent. Any ideas on this ?
