Hi mate,
For fertilizer problems all you have to do is a runoff test. Measure the EC in plain water(typically between 50-150 PPM) and water the plant with problems. Collect the runoff water from the tray and measure the EC again. I've seen some growers reading 6000 PPM(EC 12) from the runoff and that means your plants roots are almost burning :)
If you read something below 400-500 PPM then you are feeding at the proper dosage. In this case there can be a problem with the fertilizer ratios but for %99 times people overfeed their plants. Focus on the first scenario for now. Let me know what you read when testing the runoff water with an EC meter.
Hope these will help.

hey there Dave, you're right about magnesium issues, the thing is it will take more than a few days to recover. Right now you're on a heavy light cycle, so that's why the plant needs more Mg , since giving more Mg doesnt help, that means the plant needs more than it can absorb, so what you need to do is reduce your light cycle by a few hours, maybe try 14/10. hope this helps ! 🚀

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Strange discolorationThe 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.

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

N tox in full swing. Lowered feeding from 1 Tsp to 3/4 Tsp Cal/Mag, and Grow/Micro from 1/2 Tsp each to 1/4 Tsp each. Hoping this helps correct.
Is it possible that overwatering also contributed to excessive N uptake? I let the coco dry out a lot more (~4 days) this time.Week 4
