Hi all,
Been a long time lurker of this site--thanks to all of y'all who make this site what it is!
I have a very nice DWC closet grow that I've fine tuned over 4-5 grows. It's all CFL and in this last grow, I took the least active approach possible, and it's been really successful. I used to try LST and SCROG, but it was just such a pain in such a small space (I'm growing in a 16" x 24" rubbermaid, which is the largest I could fit in the corner of my closet). I now have 3 strains growing right next to each other, all with the same photoperiod and approximate size. Big Buddha Cheese, Dinafem White Widow, and Samsara Sweet Black Angel.
This is the greenest grow I've done to date, making it all the way to 5 weeks of flowering without a single discolored leaf. All I've done is raise the lights as the plant grows and some supercropping to even out the canopy.
I've used only FloraNova, grow then bloom. I've got a $14 TDS meter and the $15 GH PH kit from amazon, which I check about once a week when I add more water.
I'm now at week 8 since switching to 12/12 and I think I've got 2-4 weeks left (gonna let some go full amber for the knockout!). At this point the upper leaves have started getting some significant discoloration and brown spotting which I've attributed to less attention to PH in the last few weeks due to a crazy work schedule and potential potassium, cal/mag lockout due to residue left in the reservoir which I've never cleaned.
So, to the question:
I just today bought a matching rubbermaid reservoir and had a hell of a time switching out the old for the new. My buds were keeling over left and right and the roots had pretty much consumed the air stones, so it was really hard to make the transfer as the air tubes had been put through the side of the old reservoir.
a) Is it necessary that I remove and clean the reservoir during the grow process? I have a small water pump so I can empty the reservoir to about 1/2 an inch of water, then put in new clean water, but there's still a lot of residue on the bottom. OR do I just need to really pay attention to PPMs and PH?
b) If I do need to remove the reservoir and clean it, can anyone suggest an easier way to do it with my setup?
Thanks to any who can offer some help! Got some monster buds that I want to keep healthy!
