Is this possible nutrient burn?
MagicChelseaCrewstarted grow question 4 years ago
Sour Kush Day 24 (Coco/perlite) - brown tip appearing on lower fan leaves. I suspect it's nutrient burn. Flushed with 900cc PH neutral water, lot of runoff, PPM was 391 (PPM in 495). Should I cut back on feeding by diluting the nutrient water or by watering less frequently? TY

Lower older leaves is nothing to worry about. Your girl looks pretty happy to me. I would say 495 ppm if your using 5 scale is close to 1.0ec. To me that seems low but things look ok with your girl. Your getting near the point, when the roots engulf the fabric planter, will make you need more water so you dont leave dry spots in the root zone that creates little brown spots half way and near the top of the plant. Make sure you water to you have a lot of runoff. Cheers

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Burned or finishing early?So I'm very torn about what's going on with my Jack 47 Auto. There's part of me that feels I may have burned her, and another part that thinks she's just finishing early. I have details in the diary. Any insight about what I did "wrong" would be great!

Leaves dyingHello there. Very first grow, this is a mimosa auto that is around 7 weeks old (I should've kept a diary I know ..)
Leaves are dying and I'm not sure why. Even those who are very well exposed to light. Even edges do not look healthy. What's this ? Is it serious doc ?
Thank you
