Manhattan Project 2

Leaves started to go a little light green this last week so changed the water and added some Nitrozyme aswell as a slight mist direct to the leaves. Also had to lower the PH to 5.8 as it had crept up quite substantially at around 8.5. Other than that...Nice, healthy, bushy plants. Still a clear difference in size between the hydro and the Allmix. The netting needs changing as just can't get it taught so any recommendations appreciated. Itching to see the end result! Update 28th Feb: I think im getting a little nutrient burn on some of the leaves. Nutes have been added as per supplier directions Either that or it could be due to me spraying a little diluted Nitrozyme mix directly on the leaves a couple of days ago while the veg lights were running.
