Light Stress
What would be the better option, to raise my light further away, or adjusting the dimmer to less than 100%. Current light I’m using is a SF-1000. Thanks in advance.

Lime green leafs
I noticed the top leaves are turning more lime (see pictures of day 74). I used the same nute ratio for weeks. Should i do something, or is it simply the plant reaching the end of its life?

Yellow spot on my leaf. :) PH fluctuation ?
(Water change) I had set to 5.5 PH and waited 20 minutes. I put in my fertilizers, everything was fine. The next morning the ph had dropped to 4.7.. So I put it back up. The next morning yellow spots appeared on the leaves. Did you confirm that is due to ph fluctuation ? Thank's
