Your ph is low for a soil grow. Better nutrient uptake at 6.3 or 6.5 for soil. If you have a ph ec reader, check your runoff water for proper ph and ec levels. This is a routine for me after every water/feed. Tells me if they need higher or lower ph and also if I need to increase feed, or just water the next go round. This is doctoring 101 for cannabis. Things go out of whack in the root zone, then follows in the leaf zone. Cheers.

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.

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)

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Some sort of deficiency?I'm thinking it's lacking phosphorus, but this is a first for me. I gave bio nutrients yesterday, which also contain phosphorus. I've read that bio nutrients need a bit of time to become available to the plant.... Any other feedback is also much appreciated

Why is one of my plants turning purple at the top?One of my plants is starting to turn purple at the top, both leaves and the bud itself(As shown in photos 3, 5, and 6 for week 11). Could this possibly be bud rot or something I should be worrying about?
