A pk burn if one of the worst things that could happen to this plants. The affected leaves will never recover and continually look worse but the flowers will benefit from the extra dose of nutrients. Just back of on the feed, alot. Keep using plain water maybe do a water, water, feed, schedule at half the amount or less nutes

Leaf damage/discolouration The Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Nutrient deficiency? If yes, what's the best course of action to salvage the situation?First time grower of 3 autos, at week 8, lower leaves started turning yellow, top leaves started to get smaller/develop brown spots 2 weeks ago. Is this a nutrient deficiency problem? Soil should have been fertilized for 3 months, but I'm thinking they burned through it.

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Curled leaves and brown spots Please help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.
