Yellowing older leaves
Flavio
started grow question 6y ago
Is this a nitrogen deficiency? It's happening just on the 3 bladed leaves of the plant on the left. The plants look overall healthy, at least I think

Leafs getting pale, spotted and dying in late flowering.
Fading very quickly, most of the big fan leaves are dying now. Day 66. Happened within a week. Is there something wrong? Been using only rqs pellets and the last 2 weeks some ekstra biobizz grow.

Rapid, uniform, wide-spread leaf yellowing - flowering week 5
Entering week 5 of flowering on this photoperiod and she's experiencing wide-spread yellowing in leaves over past week. Haven't been monitoring pH or PPM, but am assuming this is nitrogen deficiency due to nutrient lockout. Can anyone confirm or recommend treatment beyond flush

What's my leaf saying?
I just moved my plants into a tent and watered, with nutrition (as above)... I saw two leaves that showed up with a rusty, burn to it... A few thoughts: 1- pH... It's been at about 6.5/7, but leaned a little high this reading. 2- Light burn... 3. Nutrition difficiency?

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Should I cut off yellow leaves?
Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

My plants are 3 years old (counting from soaking the seeds) and they are growing really fast but the leaves are a little bit yellowish in the middle. Is this some kind of deficiency or maybe something else? I’m a newbie to this and need your help guys ;)

Leaf Yellowing?
What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?
