Ok. Some growing pains in the new setup. I had a wicked low ph swing that lasted a couple of days due to a faulty ph pen. I'm probably buying a blue lab monitor on the next run.
The other old nemesis came through as well...Heat. it's been a bear trying to evacuate the lung room. One of the days got over 90f when my duct all fell out of place. It almost killed all the clones and they look a little worse for wear. some have root nubs others look dead. Now the temps are about 80f. Good for veg under LED but for flower I need to get down a bit cooler. I like 70f for flower under LED.
After fixing the ph the big plants are starting to veg again. After 2 more days of good growth I will take the lights to 75% and do another round of tie downs.
I also found chunks of salt in one of my nute bottles....so chucked that one.
That's all I can think of ATM.
