Bubblegum + OG Kush Autos

Coming along nicely, although time right now time feels like my worst enemy. I'm growing Autos and Photos together and prioritising the light cycle of the photos in order to attempt to finish them together. (Long story) At this stage Im unsure what my harvest will be like. Got around 6.5 weeks untill I have to chop these ladies regardless of how mature they are, and I was advised by other growers of my options to finish this run. I chose to try and finish them all together on 12/12 cycle allowing practically 9 full weeks of 12/12 before harvest. Seems like enough time right? Time will tell if I made the right decision but this round will be a learning lesson. From my past grows I've always given the plants enough time to finish up to my standard before harvesting, and sometimes that means leaving them to swell up for another week or more. These ladies will not have that luxury... I've done everything I can to increase the lighting, adding a 130watt flowering CFL and a 50watt led above the blue dreams. It's getting like a forest in there, and the plants seem to be loving the extra light. Tempted to add more supplemental lighting as I have extras sitting around. Been watering every 2 days 1.5 liters per plant, mixing a fresh batch of nutrients each time, PH'ing to 5.8 and airating the nutrients with an aquatic pump to oxygenate the solution. Feel as though theres not much more to do at this stage but rotate the plants every few days and to be on top of nutrient changes over the coming weeks. If anyone has any suggestions, particularly in regards to promoting heavy budset, I'm open for ideas. ;)
