Just driving... gimme 15. I see a few things@Aqua Man Can you help me out please? Thanks in advance!
Your gonna need a new light. 9000k spectrum is really off. Maybe part of it also very low wattageI have the flex star led at 12” from top of canopy
78 degrees with 62% humidity
For 10 gallons:
60 ppm starting (I add faucet water to stabilize the ph)
5 tsp cal/mag + 6 tsp micro + 9 tsp grow + 3 tsp bloom + 1/2 floralicious + 1ml King Crab
I will add down if necessary to bring the ph to 5.8 - 6. I will top it off with RO to bring the ppm to 500 - 550
No worries. Catch it all then test. But I would look into a 4000-5000k spectrum for veg lights. Should helpI should have probably said these are for veg, not flower. I’m not sure if that matters. I will check tomorrow my runoff tomorrow after I water. Do you want me to check it right after I water or let some run through, then test it? Thanks again for all your help!
Thank you!You feed similar products as me but I measure everything in ml so its hard for me to quickly see whats up. I have had this same condition before, but it happened only when I had some type of irrigation error and let the plants wilt somewhat severely.
I mix 60 gallon batches but I did 5 gallons before I had the tank in place. I used RO for a while and now use DI. PH can be a challenge especially if you are trying different things. I keep it all in a grid chart log type of thing and that makes it easy to repeat results. I've never not been able to get the PH right. One thing that was interesting is I picked up a second meter for PPM and the they are 75 apart in the 500-600 range. That was a surprise.
In 10 gallons my mix for that stage of the grow is:
Si: 20 ml / 4.25 tsp
(6.5 ml of PH Down to prepare for Cal/Mag. 1 Hour wait before adding)
Cal/Mag: 21 ml / 4.2 tsp
GH Micro: 42 ml / 8.5 tsp
GH Grow: 42 ml / 8.5 tsp
GH Bloom 20 ml / 4.25 tsp
FulPower: 125 ml / 25.3 tsp
YuccaWet: 29 ml / 5.9 tsp
GH RapidStart: 15 ml / 3 tsp
Hydrogen Peroxide 11%: 29 ml / 5.9 tsp
This puts me right at 600ppm and reasonably close - usually - to 6.0ph. I continue to dial the PH in and I rarely vary by more than .05 from 6.0. But a week later there is drift in the tank that has to be addressed. I just started noticing it.
I run the lights 24/7, watering 3 times per 24 hours until run-off.
@Aqua ManNo worries. Catch it all then test. But I would look into a 4000-5000k spectrum for veg lights. Should help
Good numbers. Could be a slight mag deficiency but what I'm really struggling with is it looks like they have to much light or heat... but it doesn't add up with your tenls or lights. I've never seen plants grown under 9000k color spectrum so maybe that has something to do with it.@Aqua Man
So, I watered the girls and it went in at 5.8ph and 580ppm. I did 1 cup of runoff and it was 5.8 ph and 510ppm. I have another plant that is showing a different deficiency and the runoff was at 5.8 ph and 710ppm. I’ve included the plant that was the higher ppm runoff.
I read the post about adding the potassium silicate to balance the RO water to 75ppm.Good numbers.

Can add 1 gram of mag sulfate per gal. Won't hurt and it's its mag will help.
Try backing the lights up to 18" and then see how they go over about 3 days.
I read the post about adding the potassium silicate to buffer the RO water to 75ppm. Should I use this with mag sulfate as well? Thanks again for all your help!I read the post about adding the potassium silicate to balance the RO water to 75ppm.
Yeah but can add the mag last.I read the post about adding the potassium silicate to buffer the RO water to 75ppm. Should I use this with mag sulfate as well? Thanks again for all your help!
So, I can use Armor Si for the potassium silicate by general hydro for it ?Yeah but can add the mag last.
Potassium silicate should be added first then allowed to mix for 15-20min then ph down to 6.5 and your nutrients added after that. This is important because silicate will raise your PH to around 10 so after allowing to .ix well you need to lh is back down before adding other nutrients to prevent precipitate.
Yup like I said mix it first and let mix for a while then ph down to 6.5 before adding other nutrients.So, I can use Armor Si for the potassium silicate by general hydro for it ?
Thank you! Thank you! Thank you!Yup like I said mix it first and let mix for a while then ph down to 6.5 before adding other nutrients.
