So, I’ve been trying to figure out what the heck has been going on with my special 2-liter lady.
Her leaves were showing both deficiency and toxicity for multiple nutrients simultaneously. The edges of her leaves were crispy. There were rust colored spots. Stems were purple. Some leaves were dark green and other lime green. Some leaves - both old and new - showed Intervenal chlorosis. Leaves were dying. This happened for both for Advanced Nutrients and Greenleaf Nutrients. But it was regardless of nutrient line. And it was regardless of the amount I was feeding. I started the Mega Crop at 3 grams/gallon mid-flower. I slowly upped it to 5 grams/gallon. I’m currently at 6 grams/gallon and it still looks like all kinds of deficiencies and burns are going on. So it wasn’t the nutrients.
The temperature has been around 76° F.
The relative humidity in my tent has been around 62%.
My nutes were pH 5.8 to 6.0.
I’m using distilled water.
I’m growing hempy bucket style. I’ve flushed with plain water a couple of times to try to remove any possible salt buildup.
I’ve got no pests in my apartment.
There’s only one more thing that I can think of and that’s my light. I’ve got an HLG 135w 4000K light. It’s currently at 30 inches (76 cm) from the top of my canopy. But it’s a hella bright light. So, my question: Can a light that is too intense cause a plant to show deficiency and toxicity simultaneously? Is there such a thing as too much light - even if it’s a safe distance away? I just dimmed my light to run a test...but I wanted to ask...has anyone ever heard of this?
