Calcium deficiency. Add a cal/mag booster to your feeding line-up or increase the dosage if already using one. Remember too, what is showing now in the leaves, is a direct reflection of what was occurring in the root zone 2 weeks ago. The damaged leaves will not recover or "heal" themselves, but new leaves should be unaffected once treatment begins.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?

Could someone help me to identify the issue my plant has?This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.
