2nd Grow after 20years (S.A.D. & Bruce Banner)

So far, everything is developing well. The Bruce Banner has been lollipopped, perhaps a little too much, but let's wait and see. I trained the S.A.D. #4 with plant clips, as three shoots became too dominant. This worked very well so far and the other shoots caught up well. I also noticed that the Bruce Banner was getting slightly yellow leaves. I don't know the exact reason, but it may have been due to the low CalMag dosage in the previous weeks. I also noticed an infestation of fungus gnats, nothing serious, but today I watered with nematodes and this problem should have disappeared.
