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.

Autofiorenti. Foglie bruciate.
Hey guys. I'm looking for advice. I did LST 2 weeks ago and slightly broke the plant. I had a phosphorus deficiency and excess nitrogen. The next time I watered, I only used 500 ml of water. Today I should water. Biobizz grow, Bloom, topmax. Should I add something in your opinion or just water?

More rusty spots
See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Yellowing too soon?
What do you think about the yellowing on the 6th week? The npk of the soil i use is 9-2-2. But its the king of yellowing when she needs more N. No dark spots, no burnt tips. This would be normal maybe on the 8/9 week i think.

Deficiency or ending cycle?
Hey! I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade? The last picture is my other plant, less severe, but same question :) Thanks!
