I was not trying for a scrog at all; the net is there to hold the plant upright. Without it, the net pot would just tip out of the lid of the reservoir. On my next grow, I'm going to switch to "lid style" net pots made for 5-gallon cans. The extra wide lid will give the plant more stability...

I change my reservoir weekly on Sundays, refilling it with five gallons of RO water, five cups of tea, and my nutrients as follows: Advanced Nutrients PH-Perfect Connoisseur 'Grow' series , Parts A & B, 40ml each Cyco Silica Supplement, 10ml (for increased stem strength) I just PH-adjust as...

Hi folks, I don't post her much but after what I've learned using this tea, I just had to share some pics. I'm currently on my third DWC grow. All three grows have been plagued with the brown slime and it was only until I discovered this thread when I figured out what I was dealing with and...

You can buy RO water from Wal-Mart for less than 40 cents a gallon. Hard to beat that. I too run a DWC (5-gallons of water in a 10-gallon reservoir) and all I use is RO water.

Too many times, I see folks saying that you must be pushing 1.2 or 1.4 EC in flower. However, I think this largely depends on the strain you're growing and how healthy the plant is to begin with. I know when I was pushing 1.2 EC, that's when I was getting a lot of leaf-tip burn. So I've cut...

Well, since you inquired @churchhaze , here's what transpired since my last posting: 11/25/2017 - Lo and behold, it appears I must have had a bacterial problem all along. After the hydrogen-peroxide flush of several days ago, I drained / refilled the reservoir with RO water and AN nutrients at...

Well, I guess my problems continue. After PH remained stable at 5.6 for about 36 hours or so, during the day yesterday my reservoir PH dropped to 4.8. She did, however, drink about a half-gallon of water. I let the reservoir go overnight without making any corrections. This morning my PH...

Good morning, folks. I thought I would post a quick update and say all is GOOD! After draining and refilling my reservoir yesterday morning, it was only a few hours until PH dropped to 5.6. Of course, my thoughts were, "Here we go again." But then when I checked my PH again last night prior...

@70's natureboy - I'm pretty confident there is nothing wrong with my meters. Both my PH and PPM meters are made by BlueLab and are high-quality units. I just checked the calibration on my PH meter using GH 4.01 and 7.0 calibration fluids and my meter is spot on. I just changed out my...

@rkymtnman - Going to the hydro store was a little disappointing actually. All they could tell me was what I already knew; Look for root rot, what kind of water are you using, what nutrients are you using, etc. They did offer to sell me a different brand of PH-Up, something a lot more...

@70's natureboy - I've been dealing with this PH issue for weeks now. If you had read through the previous couple of pages, I just tried a 24-hour RO flush in which the PH remained relatively stable. We were trying a flush to see if that made any difference. After the flush, I started with...

Good morning. PH tanked again overnight. Here are this morning's numbers: PH: Down to 4.8 PPM: Down to 350 EC: Down to .7 Water level: Unchanged from last night Unless I can figure WTF is going on, I'm hitting the Hydro store and switching brands. GH nutrients - PH-balanced my ass.

Here we go. Mixed up my water / nutrients this morning as follows: RO Water volume: 5 gallons GH Micro: 15ml GH Bloom: 30ml Technafloura MagiCal: 5ml Hydroguard: 10ml The soup above resulted in the following numbers: PPM: 410 EC: .8 After correcting the PH to 6.2, I drained and refilled...

Good morning, folks. Morning numbers: PH: Remained stable overnight at 6.6. PPM / EC: 0 (zero) Water level: Went down less than a pint.

Well, here are tonight's numbers after 11 hours of bubbling away with straight RO water: PH: Went DOWN to 6.3 from a reading of 6.6 this morning. PPM / EC: 0 (zero) Water Level: She drank a good half-gallon of water in the past 11 hours alone! A couple of the very oldest and lowest leaves...

Looking close at the tops, just a few pistils are starting to form. I'm also seeing a few pistils shooting out from some of the lower nodes.

Yes, the intake fan and exhaust fan run 24/7. It has been 11 days since I switched to flower.

Good morning, folks. Last night's PH drop was not as severe as I was expecting. Here are my morning numbers: PH: Went DOWN from 6.3 to 6.1 PPM: Went DOWN from 690 to 660 EC: Went DOWN from 1.4 to 1.3 Water Level: Went DOWN ~1 pint I went ahead and pumped out the reservoir and pumped in...

Thanks, @firsttimeARE . Bear in mind this reservoir water cycle used tap water with a PPM of 180. But I'm guessing after tomorrow's RO-water flush, best case scenario is I'd start with low nutrients anyway. I just took tonight's readings right before lights out. I'll be back in the morning...

PPMs went up from 650 this morning to 690 at present. EC remains unchanged at 1.4.
