Yellowing older leaves
Flavio
started grow question 5y 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

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?
Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.

Yellow lines on 2 leaves
Any clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

On two of the oldest plants their first true leaves are turning a yellowish color and every cotyledon appears to be yellow now. Is this due to watering or too much light or something?

Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Yellowing leaves
I have 8 plants running outdoors right now. I am feeding 3X’s a week with the humbolts starter pack. I am getting a lot of yellowing on my fan leaves. Buds look healthy and are swelling. Should I be worried?
