Transplanted 5 plants about 2/3 days ago so growth has been slowed fed them last night and woke up today to the tops of the plants being a lot lighter than there were yesterday. Moved the light up few inches to be safe for the moment.
There under a 400w MH, in coco feeding canna a and b, ph 5.8/5.9 ec 1/1.1

as shown in last picture the leaf one node down unaffected. Photo 2 probably shows the best photo of the issue.

Feeding them - 1.5ml a and b per litre, 2ml rhizotonic per litre, calmag added to water to get ec from 0 to 0.3.

im going to assume you put them under a bigger light after transplant ? Either way i agree with manfred , its just new growth. Thats just called optimum growth in our world. All the newer sets of leaves will be lighter color usually.....then a few days go by an they match the rest , then more new growth comes in lighter green. ect....
 
They haven’t grown much in the last few days so no new growth has came since really but here’s a pic from a day or 2 ago and you can see the same growth but a lot darker.

hi! i ment to say they got put in there new homes about 5 days ago and the light was changed from 2bulb 2ft t5 to 400w mh but the lighter growth has only appeared in the last like 10 hours.
 
5 days ago is perfect. That means you probably were seeing something "different" , probably not quite enough light for them girls and now they have new dirt an new light. So the tops are new growth and the other leaves right below are also new growth, they are in "speed grow mode" compared to the t5's an the other pots. They are just now rooting the new soil and i assume enjoying it. Keep doing what your doing, they look great right now.
