Looks like you've got some scarring from a Mg def.
And I've seen clones behave like that when they were allowed to sit in the prop dome too long after rooting and the roots were exposed to air and began to brown and rot. Keep an eye on the NEW growth, including root growth. Are the roots white, or do they show some brown?
stinkyattic Reviewed by stinkyattic on . Help noob with new clones PLEASE! I have had my girls now since December 14th. I am trying my best to get these going. I am using the Lucas method with GH nutes 0-5-10 B-M-G pH is 6.15 PPM is 740. I started them on this on Dec 30th with half strength for a day and a half. I had to change to full strength due to a bone head move that caused a leak. The plan was to run 1/2 strength for a week and switch to full. I had a res with full strenth when I had the leak so just switched out to full early. Water temp is 70F two long air Rating: 5
