Grow #1 - Granddaddy Purple - Indoor

Things seems to coming along nicely. I'm a bit worried about how much extra foliage there is, but just trying to keep air flow up and moisture levels down. On 8/12/24 I noticed that the tips of the upper leaves were yellowing (see close up photo). It was suggested that I cut back a bit on the nutes a bit so I'm thinking the next time I fill the basin with nutes (have been alternating) I will do 2 liters of water with 5 ml of the each (before I was doing 7). I put a twist tie gently around the base of the photographed leaf so I can get a one for one comparison as to how things play out.
