Natural color for the plant to take on as it nears the end of it's life cycle, fall colors as the other person said. You're far enough into flower that it's definitely no issue.

Same way fall leaves change colour. This mostly mostly from LED lights more so than HID lighting. No major worries later in flowering. Cheers

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer. How do you recognize spoiled fertilizer?

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 ;)

Yellowing leaves and yesterday curl down leaves after watering
I'm growing in coco. Is 500ml/2 days too short watering? Last growth happened the same with lower leaves (yellowing). It was because of nitrogen deficiency. But EC go to much up if I add more fert. I'm at 5.7 pH and 1.2 EC, 25-26°C and 65% RH now. That's why I use worm humus.

Tips turning into yellow
We started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Tip burn yellowing
I thought I had the leaf tip burn and curl handled but it’s really never subsided. My temps are 76 at hottest and humidity around 45 to 55. 1 out of 3 plants shows no symptoms but it’s the least mature. I was trying to flush but that seems to not help. Idk anymore, help!!
