DWC M-L Strawberry Lemonade First Grow

Howdy! So this week has seen some progress and some backward steps. Firstly, plant 2 is dead, as I was doing a res change last night, I dropped a glass measuring cup in the exact spot it should not have landed. Clay went everywhere and in dust lay plant 2 with both its main branches snapped off and a split down the center stem. Plant 2 has been replaced with plant 3, who has been sat on the windowsill for 22 days waiting in case something bad happens. With plant 3, my intentions are as follows; going to try and grow her as much as possible over the next two weeks, I am only going to top her once at the sixth node, so that should allow her to catch up with plant 1 a bit. Next couple weeks will be make or break for plant 3, if she doesn't like the strength of the nutrient water and fails, I am going to just going to bin her off and just go with plant 1 who will have 16 colas instead of the original plan of having 2 mainlined plants with 8 colas each. I figured the yield wont be awful going down this route as one plant will have two lights to feed from and a whole 14 gallon tank to herself. Just I guess 16 tops is going to add another week on again. Anyway, fingers crossed for plant 3, hopefully it wont come to that... Cheers!
