    I’m not worried about this. But why? I’m growing in FFOF and have just been giving it silica ph’d water and a tad bit a cal-mag. My light is sp250 growing in 5 gal grow bag

    It's the first sign of nute burn. It could be that the soil is a tad rich.

    Can you burn with cal mag or silica?

    Don't know. I've never used silica.

    It's minor. I'd water with plain ph'd water for the next feeding or 2 and see if it gets better or worse.

    What do the tip look like when you put a finger behind one?

    I don't think that's nute burn. Nute burn would be brown. I think you're seeing the first signs of N deficiency. That's how I interpret neon green tips.

    Does that mean I should start adding nutes? I haven’t added any yet

    I wouldn't just yet. Seems healthy enough as is. Just keep an eye on it and be ready to add nutes when needed.

    N deficiency would create yellow leaves at the bottom of the plant and the whole leaf would be turning light green, not just the tips.

    Could be light stress? Too much light op?

    If not then its definitely nute burn the next stage will be the yellow turns brown.

    Nothing wrong with the plant at all. Keep doing what you're doing.

    A little nute burn. It'll be ok because it will grow and get stronger
