The neon green looks like new growth to me. Happens all the time. As far as the Lucas formula.. It's freakin awesome. Easier then anything I've used before. Infact since I started using it, I stopped checking my ph. I haven't touched my ph pen in a year now, the lucas Formula tends to be calmag defficient but you won't notice till she's mature probably. But in soil it might not matter. 600-700 for veg is good, but only after 2 weeks and their a bit bigger. In early progression I start em at 350 and raise it 25 ppms to 30 each day till it hits 500 and stay there for a week. Just IMO, looks good an healthy though.
