Green_Coffeestarted grow question 5y ago
Problem is mainly occurring on leaves near the top, but not the newest growth. Initially are less green, then start to yellow followed with brown spots. The oldest leaves near the bottom are seeing some effects, but as acute as the mid-upper leaves. Curl likely due to warm temp

It's my opinion that you're looking at a potassium deficiency, but there is also a small possibility this could be a Nitrogen deficiency.

Bottom fan leaves turning Yellow on week 8... Emergency, or all good ?I know It's a Nitrogen deficiency. No nuts during veg (and fine!), and she's having flowering nuts since 2 days.
I know it's normal at the end of the flowering, but i'm wondering if that's too soon !?
Not sure how many time left before harvest!? Big problem or not?

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.
Biobizz soil and nutrients.
Thanks in advance!

Leaf DiscolourationI 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?

Yellow Leaf on mid flowering stage.Hello everyone, how is growing?
I noticed some leaves turning yellow on the last week, I'm not sure if I overfeed them or if it is some kind of reaction because I put a new fun in the grow. Does anyone have the same kind of situation? Because it happened only in one of the plantWeek 10

Nutrient lock out?Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.
