The insides of a small number of future bud sites are showing some strange purple discoloration. My initial thought was that this could somehow be mold however under the microscope it is very purple. Any ideas or suggestions would be greatly appreciated. (see images week 11)

Nutrient burn, Light burn, or Phos Def? red stems purple bruises,
Noticed red lines leaking red into the leaves with purple bruising, and the starter bottom leaves seem to be turning yellow, with the leaves above looking dark green with spots. Is this signs of light burn or nutrient toxicity? And is it lacking phosphorus or just the strain gen?

Strange discoloration
The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Brown spots on leaves! To Flush or not to Flush? That is the Question.
Hello, Seeing lots of brown spots developing around middle tier leaves. Reddit is telling me I should flush with 15 gallons of water to get rid of salts around the roots. That seems extreme but if that’s the cure I’d like to know more and can I use my tap water (7.1pH 133ppm)?

Purple leaves
Hi Guys, some of my leaves are developing a purple shine. I guess its because of a nutrient deficiency but im not 100% sure. Im watering every week once with 0,4-0,5ml of Bio Grow. What should I do now?

Another round of Name That Deficiency
5 weeks into flower and this plant seems to be the problem child but she’s also the one showing the most growth. PH is 6 on her, was originally 6.2 but was having a manganese deficiency so went down to 6.0. Gave 3/4 of recommended nutrients in last feeding. Not sure what to do.

Curling leaves with purple tinge
Had to leave plants for four days. Watered with 1L of water before I left. Arrived to 31c temps and leaves curling with a purple tinge to older leaves. Assuming heat stress mixed with overwatering. Thoughts?
