answered grow question 6y ago
how many nutrients (and how often) do you feed them? yellowing/browning of the tip of the leaves is often caused by nutrient burn (overfertilization)

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?
