Stunted growth, all of my 6 plants are exhibiting the same growing issue
The plants are producing a large amount of new growth branch wise
The internoidal spacing is extremely tight together
Problem is the plants aren’t growing in length?
Thats certainly intense light thing... back up your light by say 5 to 7 inches and you shall see the difference..though this is good if you want to control your plants height!! Also gives tighter bud structers(your current light height). I always grew like this ; helps you in training them well. Hope this helps....
The way they are tacoing and close nodes yet otherwise healthy leads me to think your light may be too intense at their age. Try backing the light off 4-6 inches more. Whats your heat and humidity like?
