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

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Deficienty
Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

Yellow spots on bottom leaves.
Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.

Slight leaf tip "burn"
What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000

Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.
