Depends If coco is present in your substrate. If so then I would use it more often then not coco absorbs cal mag.

What nutrient is causing this?
I know for a fact that it is some kind of nutrient issue. I’m not sure what but that’s what makes the most sense. Because it ONLY shows on very early growth and then disappears as the new leaves continue to grow. I’ve been through very cold weather and never seen this.

Hi Legend, Not sure about it. Magnesium, Calcium, Ph. Maybe uptake or loss. She is growing well, big healthy. Ready for a second round of clones. After, I will let her sign in a bigger airy pot. Thank you for any suggestions 🙏

Purp stalks, weak leaves.
Hey guys i noticed that my stalks were all turning purple and my leaves are curling. Is this a nute lock out ? Or is it light burn ? I started them under a pretty powerful Led but still getting new growth through the last 2 days. They look thirsty but medium is still soaked.

Should I flush? (Overfeeding)
I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Add CalMag or Manganese? Still slightly discolored and veiny leaves on week 6
Calcium or Manganese deficiency? Last week had what I thought was early calcium deficiency. Gave it a dose of CalMag but now not sure if it’s still Calcium or possibly Manganese. I do mean manganese but I realize it could be a CalMag or Manganese deficiency as well.

Nute lock or nute deficiancy?
had some yellow leaves start to pop up on one of the girls. Looks like a nute lock that we will address with a PH water flush and then slowly wrk them back up onto the feeding schedule. Didn't check my Ph and my guess is Ph went too high in the soil.. Thoughts from my gurus?😇
