Seedsman Auto Lemon Hydro Grow

Didn't change the water again for week 3 as it contains Silver Bullet Roots which protects plants from bad bacteria and root rot for up to 5 weeks. Monitored the PH of the water again and maintained it to a PH of 5.9 I'm still to watering with 20ml of solution but now only 2 times a day to keep the roots moist. With my LED light I put both the Veg and Bloom switches on so the plant is getting more watts of light and I've raised it by an inch so it's still 18 inches from the plant. The Auto Lemon grew about an inch which is the fastest development I've seen from this plant so far. She has now started to develop its 4th set of fan leaves. I've also notices that I possibly have another strain with a few abnormalities with leaf growth, I'm hoping she grows out of it. To add to the plant problems she seems to have killed off 1 leaf and node from the 4th set, I'm not sure why this has happened but i'm hoping this doesn't stunt her as shes already going to be short.
