Leaf spots

OGSeshstarted grow question 5y ago

Hi guys. These spots have formed on the lower leaves. Is it a cal-mag deficit or maybe is it due to strong airflow? Also, are they already big enough to switch to 12/12 light or give them another week? Thanks!

Thanks, I will lower the fertilizer dosage. Is it a good idea to do next watering with GHE FloraKleen, without fertilizer?

Your ppm is way to high. You should be at 7 or 800 ppm not 1500. Run some water through until you get the nutes lowered. Cheers

They are looking much better this week. Can’t pinpoint it exactly- but looking at your feedings, it might be a bit of over feeding. She’s dark green- maybe a tad too much nitrogen. But those bottom fan leaves tend to be the oldest and can suffer from lack of light even before you hit flower. Seems cosmetic at this moment. 🌱

What's happening with the leaves? 🍁🍁 The bottom leaves are drying out and dying, but the bud's leaves are slowly turning yellow. Is this a sign that I'm close to harvest or something bad? Thank you all 😁

Barney's Farm - Amnesia Lemon bad seedling?My seedling is now 14 days since germination and planting in soil. I have the feeling that the growth is slow and the leaves are deformed. Should I start over? I'd rather try to save this one since I'm outdoors in north Europe and don't want to miss too much of the grow season.

Defoliation of Fan leaves. The COBRA's growth structure is very tight nodes with large, Indica-type fan leaves. The largest one (3rd pic) has tripled in size from the last photo. I have been bending the leaves under side-branches. Can or should I cut them off to allow light in?
