Dark green leaves, clawing tips, and yellow tips are all dead giveaways.

Yep that's nitrogen toxicity. Your soil probably has a buildup. Test your runoff. If it's a little high, just water at half strength until it's in the proper EC range. If it's very high, flush it.

deficiency symptomsI'm a beginner and some plants are getting fallen leaves. They are being watered with the amount of approximately 10% of the volume of the pot and an average pH of 6.5. Runtz has Mag deficiency symptoms after I fertilized, is she also lacking N deficiency?
