Dwc Slow Growth Wtf

Currently setting Ph using liquid test so I know I'm at least between 5.5 and 6.0 give or take .2 . I adjpust Ph after adding nutes. My municipal water contains no chloramine. I know I need a much more accurate means of monitoring Ph but I'm broke right now. Been looking at multitesters but kinda stickershocked. Can I use an ohmmeter to measure EC? Point of note, tried using Brita filter, shot Ph way up to 8.0+ when tap water was around 5.0. Got my money back on that ish and bought an xtra air pump. Each rez has a dedicated pump outlet now, frothy! Started from bagseed, not by choice but by financial and security reasons. Got three good seeds from a friend two made it to transplant. Will definitely be doing some selective cloning with the strongest fems down the road and hoping to enjoy whatever else comes from my efforts. Thanks so much for all the input keep the good stuff coming

Our walmart has RO water for 0.37 if you bring your own jug, is a culligian station, self serve. PPM checks out at 20.
 
Ill check it out. They look happy today. My nutes are dynagrow GROW, being used at the strength indicated on the label for non recirculating hydrocultureq. The plants are lime green and show no signs of nuteburn, think I can up the concentration? Label calls for one tsp per gallon for non recirculating systems, two tsp per gal for record systems. Anyone use these nutes before? What was your concentration?

Only thing I would suggest is lower your light! Three feet is pretty damn high to say the least! As long as you have decent air flow in there, you should be able to get the light a foot lower at the very least!?

I quickly skimmed through the responses anyone in hydo with tell you that temps are key to explosive growth!!!!! rez temps at 64 is way to low hike it up to 72f to 74f degrees... I promise if you do that you will watch your plant explode. I live in cali and this winter I learn a valuble lesson in temp control.... I have had two really good summers in my shed but I lost everything this winter when the outside temps were in the 40's my rez temps were at 62... Hope this helps

Sorry to burst your bubble... but you are incorrect. Next summer when it pours rain, go collect some and measure the temperature of it.

And a res temp of 72-74 is a fucking invitation for bad microbes. Cyanobacteria by lunch anyone? You need to lower your light like suggested and stop stressing about chlorine, it's been beat to death multiple times that if you can drink your tap water, so can your plants...

On a side note your plants look pretty healthy they're just not completing photosynthesis fast enough to allow for dwc to constantly supply nutes. More light=More nute uptake = vigor :)

Well the plants don't look like they are lacking anything, but sometimes too much nitrogen can cause really slow growth...I would try easing off on the N a little and just see if it works out any better...Might, might not, but they look good, but they do look very small for how old they are.

Try running only half of the recommended dose. start with 1 teaspoon per gal, top out at less than 1.5 teaspoons per gallon.

Hps is for flowering. You want MH for veg. And also if your vegging light should be on 18/6. When you change out the water have a back up bucket fill it up for the next watering and let sit until next watering and so on. Good luck
 
Your plants look awesome! It looks like you started from seed... Starting from seed will take longer for sure... I usually add about 2 or 3 weeks to my veg time if starting from seed...

On a side note, you can veg and flower under both MH and HPS... I actually prefer to flower sativas under MH because the blue in the spectrum helps keep them from stretching as much... I have a combination of HPS and MH in my veg and flower... They all do the same thing...
 
Look bro, you need to take all this guess work out of the equation. RO Water from grocery store, 5 gallons for $1.50 buy PPM/TDS meter and up nutrients slowly depending on how plants respond. Around 1500 ppm in your time frame would suit them well. They are way small for that amount of time. Healthy looking though, so dont worry too much. Good luck and happy growing.

1500ppm is bad advice unless you are growing salt water kush. 420ppm is the magic number for dynagrow and doobage

Well everyone has their opinion so here is mine. Without drip emitters your roots arent getting the water and nutrients they need until the root reaches the reservoir. So You would need to water and rehydrate the root zone alot until they reach the reservoir... at that point the growth will pick up like it should.
