Mars Hydro Lemon Jack

A great week for growth. However I'm seeing a few leaf problems beginning. Early in the week I started to see some leaf discoloration, which could have been some light burn but more likely some ph fluctuations. Towards the end of the week I'm seeing leaves with raised edges which I think must be due to the low humidity and the temps being a bit higher than ideal. Unfortunately the higher I kick up the power on my light, the higher the temperature gets. I currently have one small 4 inch intake fan and an oscillating fan but I think its time to bring in the big guns and add in a 6 inch fan and turn the 4 inch into an exhaust rather than intake. Anything to keep the air exchange continuously flowing. Besides the heat I'm loving the new Mars Hydro SP6500 LED, its powerful, beautiful and dims. It does take up a large amount of space though so I'll plan for that better in the next grow.
