I changed the reservoir and set the pH to around 5.3 and reduced the nutrients by 5ml/g.
I just realized I've been adding far far fewer nutrients than I thought. I've been using 30ml in a 5 gal bucket (probably 4.5g volume) but I should be using 30ml/g so 4x as much. I'm going to leave it for now but I should probably start adding more nutrients.
I took the wires I was using for LST off the bucket so it isn't stressed during flower and so it's easier to change the water. I'm taking off fan leaves that are blocking bud sites if I can't tuck them away. It grew a crazy amount today, so many little pistils came out. It's an exciting time.
July 10 she thirsty. I added half a gallon of water and a full 30ml of each nutrient. That should bring us close to half the recommended nutes. I'll probably change the full res out and give 3/4 nutes sometime this week and go up to full strength next weekend if everything looks OK.

I just looked at my chart again and I think I was right the first time. I just added more nutrients for no reason. I added another half gallon of water and checked ppm and pH. Ppm is 1050, pH is 5.8. Gonna keep an eye on it through the day and see what happens.
305pm pH 5.8 ppm 1200
July 11 pH 5.8 ppm 1300. I'll add some plain water after the res goes down a bit more. Looks like the plant isn't using all the available nutes and is probably leaching some. She looks good though. Loads of vertical growth over the past week, now really going hard making bud sites. I'm going to see how this nute situation goes before doing any major defoliation or pruning. Leaf temp was 29 on the central cola so I turned up the fans and raised the light a bit.
July 12 ppm down to 1200, pH still 5.8. Looks like it's going to be ok.
July 13 ppm 1300 pH 6.2. I dropped an entire oscillating fan on my plant today. I broke 4 stems almost clean off. 3 appear to be surviving through duct tape and wire. The biggest one appears to be a casualty. I'm pissed. But the cabinet is coming together. Once it's perfect this kind of thing won't happen. I salvaged a piece of plywood yesterday and hand sawed the whole thing to fit as a door.
I made a countertop tent out of mylar and 2x2s. Any tips on what I can hang on the front to dampen the sound of fans and filters? Foam didn't do much so I broke it into smaller pieces to block off the noisy fans and pumps individually. I'd like to isolate the whole thing ideally.
20 slot Egg cartons mate, great sound dampener, used it in a band practice room years ago to dampen sound and it worked a treat - same prinicipal as sound proof foaming but a whole lot cheaper. If you were to build a front you could put stick the egg cartons inside to dampen sound.
Another cheap alternative is expanding foam between 2 thin pieces of wood - get some clamps (6 should do it) spray your foam LIGHTLY across one board, stick the other board on top of itnand clamp them down so youve got about an inch gap for the foam to expand and itll stick the boards together too, use sparingly cause it expands like a mo'fo, some of them are also fireproof too, if youre the safety conscious (paranoid) sort. ;)
I'm using a 1000w HID setup I had from before, running at 50% in a cool tube. It's loud and not efficient. Maybe it's time I switch to LEDs or a 250 HID. I don't want to sacrifice bud quality but I'm low on funds. Any recommendations for a good light that will fill this space?
Being in a dwc bucket you will want a detachable driver. Mars lights have high output vs quantum boards. I have used both. I have only used ts series though for Mars. Detachable diver allows you to remove the heat it produces in grow space. Help keep dwc cooler. Can also line your bucket with reflective mylar if temps in bucket are getting too warm. Good luck
After this run I think I'm going to grow 2 DWC autos at a time and harvest monthly. I'm looking at a 6x 3k COB, a 58 SMLEDs 2 CREE COBs (3k and 5k), or a 112 SMLED and 4 CREE COB (3k).

Those are all meh lights. I've actually used that 6x cob led light before. it's a 280w space heater that does provide some light. it'll probably be fine for ~10-12k hours, then it'll dim like crazy cause those things run hot AF. the other ones are mixing an older tech (COB LED) with an even older tech of LED diodes. They are all lying about PAR values. the last one shows a 34.26lm/w efficiency which would be 1/6th of a cheap unit with new technology used, if true. they don't even know how to lie correctly.
that 280w 6x cob can cover about 3'x2' - mainly due to shape and the reflectors used. it is expensive and hot, despite the 0 up front cost.
get something inexpensive to start like a mars or vipar to cover your area. they are 'okay' lights. they too lie about umol/s and PAR etc more times than not..
when you look at better equipment, they'll often be more honest about the specs. umol/s is the best way to determine how much you need... ambient co2, you are fine 60-80umol/s per square foot. this'll be ~800-900 PPFD? can google the math on that. If you add/regulate CO2 you can probably push 100-120umol/s per square foot.
watts does not work for this, because efficacy varies. a high-end 100w light might provide more photons of light than one with 120-140watts. cheaper lights -- 40watts / sq ft. expensive lights ~30w per square foot. you can do a break-even analysis of your electricity savings per month and decide between 2 lights with more confidence of buying best value. (requires accurate specs or algebra skills to deduce it yourself.)
Anyway... i'd take it easy on the light until you can resolve the best ones.. before spending too much. Get a light that uses bars/strips of LED spaced out covering most of your area. it provides a very even blanket of light across entire canopy.
My grow hits 60 days on August 25 but I have to fly on August 28. I also just stopped giving nutes yesterday but should have tapered sooner, especially cal/mag. I want to do a flush/dark period/chop/wet trim/wash/hang dry before I fly. Any tips on a drying schedule? It's tight.
Well if you take them down now and wet trim your bud then hang until almost dry 4 to 5 days, jar and burp the rest of your time that your home, them the day you leave it still won't be ready to jar and just leave so in the freezer they go until you get home and can finish the burping. I have had to do this before and had no problems finishing up the process when I got home. Cheers
Awesome setup, i've read that top feed in the beginning of a dwc grow can speed up growth before roots even hit the water, and that seems to be the case for you
@jonesy_grows, thanks! I do think it helped. I haven't turned the top feed on since the roots were submerged but I do think it helped in the beginning!
