NFT system update
So have been working the last week to increase my dissolved O2 and after high false reading i was able to increase my O2 to roughly 9-10mg/l using a home made Venturi. I also did measure some return water and noticed i had a 1mg/l drop from the reservoir to the return line.
My new plants are really growing quick they are already trying to flower and i will say the new roots are looking amazing compared to past attempts. I always say I’m going to clip the first flowers, but then i feel so guilty about cutting flowers.
I have noticed a little more brown tip burn and I’m not quite sure what perimeter could be the culprit. My room temp has been rising recently, now in the low to mid 60’s. Maybe my ec is low, but I’ve been keeping it at 1.2-1.4 and ph is 5.9 or so.
Still getting a few nice berries, but looks like a number of flowers and buds are turning gray or not developing once open.
The blown leaf in the photos is an older leaf. Not sure if my P is low and need to hold back on the N.
