I have 3 Cannatonnic plants in 5th week of flower. They are in FFOF soil, 3 gallon bags, indoors, 90 watt LED light with 8 extra small LED strips along sides, run-off PH 6.5-7, tap water .4EC and 6-7 PH going in, just started FloraNova Bloom nute routine at 1.7EC, watering is “drench and drought”. Any suggestions? Too much light or perhaps (I hope) they are just turning colors due to maturity? This plant got it first FloraNove Bloom nutes this morning. Thanks to all! jm
Hi there! I would go with maturity. Week 5 of flower, means just over half way there. and with lower temps sometimes plants like to give off fall colors. The leaves do have some white spots on them. Was this from spilled water or nutes?
Temps/environment?
70 - 75, 35-45% humidity
Don’t know about the white spots. I’m keeping an eye on them.
Your slightly lower temps might be just bringing out fall colors for maturity but otherwise your environment should be okay…I’ll defer to those more knowledgeable on the nutrient side of things since I do not feed. Good luck!
I feel those ranges are fine. Keep an eye on it, but quite honestly unless there are some nutrient deficiencies or excesses not fully known, I’d say it is late flower colorations. Keep us posted. 
Thank you.
No, 70-75 degrees F. Your bud looks very similar to mine with the discoloration.
Nice! I got 4-5 more weeks on my first indoor grow. I learned a lot and next year I’ll be making some changes.
