First Grow - Triple Automatic: Purple Haze, Apple Fritter, Purple CousKush

As a total newbie I was a bit furious about the many diaries that skipped so many weeks in flower, but I get it now. There isn't really much (visually) happening. What have I done the last two weeks: Mainly trying to compensate the small size of my Purple Kush (35cm) first with a Trellix Net and LST on the top bud of the way higher grown Apple Fritter (55cm) to even out light. I was afraid that might ruin the top bud of the Apple Fritter so instead I lifted the Purple Kush up on another pot, now they're about even and get the same light. I fed (perhaps too much on the lower end) with Plagron Terra Bloom and Power Roots. Quite some lower leafs are turning yellow. I also lowered PH from 6.4 to around 6. The picture shows my lousy attempt to bend down the top bud of the apple fritter.
