answered grow question 4y ago
Looks like a cal/mag issue starting up or PH is imbalanced causing a lock up.

Light Burn, Nutrients, Neither?
This has progress quickly on older leaves at the canopy. I increased CaliMagic a couple weeks ago to 1.5 from .8ml/gal. Light was cooking the canopy for a couple weeks. Modified the cabinet, new light, optimal distance/PPFD. Light burn or food related? Mold or Fungus?

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.

Yellowing veins?
Any idea what could be causing this? The yellowing stems from the veins rather than between. Any picture I find online of something similar 404s. I might have fixed it in my next set of leaves, but still baffled.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?
Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

Leaves are turning yellow from the bottom up and I'm not sure if it's the natural death of unessery lower leaves or a nitrogen deficiency. It's not a ph problem. Thoughts?

Excess or Defiancy?
Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.
