Damn thrips…. The Cucumeris Mite is a great option for integrated pest control.
MANTIS is a blend of 11 micro and macro ingredients and it was specifically designed for cannabis. There are no supplementary sugars or microbes added to it.
It’s actually funny how big cannabis can grow in solo cups. Well maybe not if you look at Grodan Rockwell cubes…seeing a nice green colour to the leaves, I promise to do some ppm and ph analysis. Actually I have just been trying to slow these down to make some room.
Hmmm the middle plant looks a bit hurting that for sure. Any chance that you might have fed it without mixing properly?
Maybe the mixing jug had concentrate at the bottom and hit that plant hard?
I would suggest to do a small flush with that plant and then get back to the regular feeding schedule. It does not make sense that it is missing nitrogen as the other plants are so happy.
