<span class="link_user">@MalumProhibitum</span>, I have noticed the same thing and for the next grow I plan to double the ammount of Bags (add a row on top) and to leave out the bottom 2 clones from every grow. It took me a few weeks to figure out how much each bag need every day in this freakin heat. I soak them now till about half a cup drips out about 5 min after watering and added 1 extra ml nutrient per litre. The problem has now ceased..
New method, just figuring out the bugs. Been growing for close to 30 years, never too pridefull to take advise.
