started grow question 1y ago
Any idea what these bright spots can mean? Plant is 2 1/2 weeks old and those spots show only on older growth.

Looks more like a pH issue. Was the coco washed and buffered? Many brands claim to already be....how well they did so is often debatable.

Leaves color changing in flower!!!!
what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower? max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout? today i fed with 4.5 litres of compost tea + enzymes! pots are 14L.

Changed light to flowering and all of a sudden the plants started to bleach white on the new growths and wilt at the bottom. Assumed excess nitrogen. I recently flushed them but they do not seem to be recovering at all. Quite damp. Strains are Blue Gelato 41 Bluberry OG. Thank

I'm entering week 7, what's happening?
I'm entering week 7 from germination. I'm using a soil for herbs/lawns (pH 8) as an amendment—not ideal for cannabis. I'm testing it, but leaves look like this. I fertilize and already flushed. Using 1ml grow + 1.6ml bloom Biobizz in 500ml water (pot is 3.2L).

Discolored leaves, rust spots, and burnt tips
Began with burnt tips, followed by rust spots on upper leaves. Then top leaves of new flowers came in yellow, followed by bottom leaves developing gross pale spots. Not sure why, please refer to my super soil recipe as well as the one feeding I did in week 5. Underfed, pests, ph?

Light green leaves
I received some clones and leaves are turning into a light green. I suspect a lack of iron, calcium, magnesium. What is your feedback regarding the pictures? I added some calcium-magnesium and Fish Force to the water last time.

Slight discoloration in the leaves
The leaves are starting to get slightly discolored on the edges, what could be causing this? Could it be the white flies? Or could it be too many nutrients? I am giving the plant a bit of Canna A and B, although it's meant for hydroponic, it's all I have at the moment.

Deficiency?
I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

Root rot or pH imbalance?
This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

What’s wrong ?
This plant has displayed this yellowing in a couple of its older leaves. It hasn’t gotten better with the exclusion of nutrients it doesn’t seem to be hurting the growth of the plant as it has continued to grow over the past week. Is this something I should be concerned about?
