What is wrong with my Zombie Kush?

Hi, my Plant has somethink butti don't now what maybe a Phosphorus deficiencie?

Feeding her for Vege not more than 1.2 EC Medium is Coco. Yesterday I saw this after switching to 12/12 for the first time and increase the Nutes to 1.6. The run off EC are 0.6 maybe she is Hungry and I feed not enough but this goes on so quickly in Days.

Ph are 5.5-6.0


I hope someone can Help

What kind of light are you running and how high is it? Tacoing of the leaves like that is usually a magnesium deficiency.

I’m no pro though so wait a few hours for our resident experts to wake up and give their advice.

2 x cob Leds 110 watts That's defenetley not to much.

Where are the pros

tacoing like that has to do with heat/humidity. Too hot/not humid enough will taco the leaves so they can hang on to the water. The markings on the leaves is an 'old' magnesium deficiency. It may still exist, though i don't see much paling in that sense. What you're seeing, originally started with slight yellowing/paling and after at least 2 weeks, it turns necrotic like yours did. Maybe you fixed the issue since, or i just can't see in the pics that it's still there. Coco, will need to be fed extra cal/mag into flowering, especially if you didn't buffer the coco prior to planting in it.
