Weekly Temperatures
Summer's here in Virginia. With temperatures up in the 90s, we had a great long holiday weekend. I got to spend some time out at the lake and had a nice cookout. Luckily with the A/C running the basement's staying fairly cool. I'd like to get my night temperatures a little lower, but that isn't going to happen during the summer. The exhaust fan is keeping the humidity in the low 50s/high 40s and the VPD around 1.4-1.6 as we come to the end of flower.
I think the
@Sierra Natural Science 217-C has the spider mites under control. Since I found the mites, I've sprayed the plants four times about three days apart. When I spray, I try to drench the undersides of the leaves as much as possible, then give a good coating on top. I spray right before lights-out, and the exhaust fan kicks on high until the humidity goes back down. It all dries out before morning and lights-on.
I've taken a couple of the worse leaves off and I can't find anything moving on them. I'm watching the rest of the canopy for any signs and right now I don't see them spreading. I'll keep a close eye on them and I'll keep the spray bottle handy. And of course, after this grow the tent will be deep cleaned before the next grow. I'm using the SNS-209 on my other plants as a preventative. One thing I haven't been able to figure out.
@Sierra Natural Science , can I use SNS-209 in DWC/Hydro? It has instructions for using it as a drench, but does not say if it can be used in hydro. Any info?
The PPMs of the system have gotten pretty high so I've been adding water lately. These ladies have been in the RDWC system for 66 days. Since the original 44 gallon fill-up, I've added 85 gallons of nutrients and 24 gallons of water (about 2.5 times the original volume). The problem is that I have no idea what nutrients are making up the 1300ppm at this point. The only way to balance the system is to start from scratch. I really should've done it two weeks ago. I'll know better next time.
If it were a couple of weeks earlier, I'd go ahead and change the res. Midway through week 8, though, I'm not sure it's worth it. I put a little bit of Epsom salt in the water today to bump up the magnesium, as I know I have about 80-100ppm calcium carbonates in my water. Other than that, I'm going to just add water for another week and see what happens. They should be tailing off the feeding soon anyways.
I'm seeing a few issues with some of the leaves and starting to see some purpling already. I'm not sure if this is a res issue or from spraying the buds four times in the last two weeks, or both. Right now it's not too bad so I'm just going to ride with it. There's a lot of brown pistils in there and they may just be finishing up. They're in week 8 of flower now, so at most there are 2 or 3 weeks to go. It's been quite the journey to get here, and there were several times I wasn't sure they'd make it. While this may not be my best grow I've learned a lot. I'm already looking forward to the next time where I can fix all the mistakes I made with these girls. Until then, I'm going to keep the bugs at bay and try to ride this res into harvest.
Can you believe it's June already? The pool should reach 75f today so it's finally time for a dip. Hope you're staying cool wherever you are. Enjoy the rest of your week and stay safe everyone!
Stay safe and have fun!
I can't keep my humidity low enough and the the temp is a tad low but hoping for better numbers ad the heat of the summer kicks in and the AC turns on more
