Cause of these yellowing leaves?
RJP17started grow question 6y ago
Bottom leaves are starting to turn yellow with brown patches also appearing on both plants. I think it’s a nitrogen deficiency as I’ve been feeding a little light (around 450ppm), can anyone confirm? How do I go about correcting this?

Color en las hojasAt the beginning of week 3 of flowering, the leaves are orange, we stopped fertilizing and the problem continues. It's a 10-liter pot, watered with a liter every 3 days, it's a Critical+ auto from Dinafem. I want to solve it but I don't know how, we're in week 4.

Phosphorus? Potassium? CalMag? What is going on here?So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Deficiency?Hey everybody,
I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors.
Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos.
Please let me know, thanks!

Calcium, lock out?Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

Deficiency ProblemsI don't know why they suddenly show so much deficiency.
Do I need to readjust the PH level or add more nutrients
Could it be because of the stronger lamp?
