Diagnosis issue

JaySB · Jun 6, 2020

Hello
I have started a few seeds may 27. The strain is super skunk.
I started them in a few different mediums. A few in a seed starting mix. A few in jiffy pellets and two in some Rockwool. The plants seem to be doing well. I have lightly fed with nutrients a day ago gh three part system. Other than that I have only used water. I bottom watered only from the tray when the mediums have dried up. Ph of water has been between 6-6.2 68°f.
I have noticed a few leaves cannoing and I have also notice a few brown tips from the seedlings in the Rockwool.
Any advice I could be doing wrong would be very much appreciated
Thanks.

Leaf cannoing in seed starting mix

Canoeing or Tacoing is usually caused by too much heat or too much light. How close to the lights are they? I'm not a rockwool guy so I can't comment on them, but I think it is light/heat related, not nutrient issues.

They are about six inches from the light which is a t5 ho. It doesn’t seem to be producing much heat but I can definitely try moving them down from the light.

Moved the plants down after yesterday’s post. Woke up today and a few leaves seem to be hurting still. The plants look healthy otherwise. Anyone have any other ideas what could have done this ?

Thought I would provide an update for anyone interested. Plants are doing well. Have one plant in a non circulating water culture which is doing really well from what it was a week ago. Waiting to build my dwc buckets until I get a few new lights. Other than that all the plants in soil are doing extremely well and are all ready to be transplanted into some big pots
