Thanks @Bigb2
I’m using a Bluelabs Truncheon meter to check my runoff. It helps to monitor the ppm of nutrients.
This might help you out DannyO. I was having issues with leaves getting lighter green and turning yellow. I’m using lush soil and I’m assuming that my girls exhausted all the nutrients in the soil. I just added nutrients per manufacturer recommendations and checked with the meter. Got a confirmation that I was within the range I wanted to be immediately.
I actually added a little more fertilizer than recommended due to the fact I’m running my lights at maximum and supplementing with c02 when the lights are off.
@DannyO do you have a ppm and ph meter ? I would suggest ypu do a slurry to check your numbers. Cal Mag is not needed with your soil. You can actually lock out other nutrients with too much calcium. Since your overall plants look the same, im leaning towards a ph lockout. Need to confirm though with a soil slurry.
I do have a new AC Infinity PH pen which I believe can also test PPM. How do I do a soil slurry?

I have not tested my organic grows 1 single time. I have made the soil hot. Cold. In between. I am a seat of the pants grower with organics. Measured everything when synthetics.
Gg4 has a few quirks.
It is VERY VERY ph sensitive. I kid not or exagerate here.
Thirsty girls. Will dry fast. Large veg.
They get very thick. Require some maintenance for airflow. Love silica.
They train very well..a good thing.
They dont like to be pounded with light. 1 of the few strains i back off a bit on. HUNGRY girls. They grow big and eat a lot.
If I am not mistaken gg4 was an accident.
I personally grew my last gg bean for 2 years cloned. Largest yield was 2.5lb dry. 3x3 with 20gallon pot. HUGE plant for the space.
PH was always an issue till turned last clones organic. Strong life in the organics is key here I believe. Some recharge or other brand of life should be added either weekly or every couple weeks.
PH PH PH!!! Even with the life I would keep the ph very tight till soil has cooked well and life is thriving. Some fuzz on top of soil indicates strong soil life. With organics if you have soil too hot and a few burn issues GROW THROUGH IT. Do not flush. As the plant uses up available nutes she will stabilize. After they recover can resume your top dress.
PH PH PH…LMAO.
Only strain that has ever given me ph fits. Super finicky.
Being such pigs I have had to top dress a little more than other strains.
2 years of constant clones allowed me a lot of firsthand observations. Killed a WHOLE scrog. Ph. Burned a couple plants,full recovery, over ammended. My ph here is 9-10 from reservoir. Sometimes even the life wont get it where gg4 likes it.
I would ph your water diligently for now. After reusing the soil and it becomes a thriving biosphere the ph is easier to control.
Just thoughts from my gg4 runs. Thinking of doing another run. VERY VERY solid strain. Pain in the butt at times but solid firm flowers. High THC. Great flavor. Super for edibles and hash also. Extremely good strain for medical. Sorry for the novel. Somewhere up here..year or 2 back..are photos of my gg runs. Even photos of a scrog dieng in front of my face. Last scrog ever. Too hard to get in and fixem.
Pics of current living soil grow. Just so you know I am not blowing smoke up your butt.
Dont know strains. Have a lot of seeds from friends up here. I just grab a few and grow. Never look at strain unless a particular strain I want. Been growing way too long. Just a tent with weeds in it to me now. Even stopped training besides fim.
If do need some calmag a foliar application is all you need. Not often and not a lot. 1 thing i see in my reused soil is being mag deficient. I add epsom and roll on.
Great!! You have given me hope I can grow through this! Thanks very much!
And thanks to everyone for your input, this only my second indoor grow so learning everyday!
Agains thanks everyone!
Hello All
Need your help again. What causes the brown tips on the plants? Growing in coast of Maine platinum, after seven weeks. I top dressed with worm castings and down to earth 444 fertilizer, 1 tsp per gal of soil, I’m in 5 gal grow bags. I’m watering with tap water ph’d to 6.4 adding 12 to 14 oz of Recharge after watering every other watering.
Often referred to as “painted nails” and observed right at the threshold of the max nutrients your plant can obtain. A lot of growers strive to see this as it lets them know just how much they can push. Maybe dial her back just a very little touch to prevent nutrient burn. Overall, nothing to be overly concerned with but a noteworthy signal to acknowledge. Girls are looking great btw… keep it going!!!
Thanks @PhatPat , that’s great to hear, just going to water and not top dress again until we get a couple weeks into flower.
What @PhatPat said. I run that line always even in organic…grin.
I consider it a good thing. The GG4 is a piggy and loves water so good uptake like that is great. Stay that line i say and you are right where she can thrive.
Thanks @Storm. I’m going to wait a couple more weeks then flip to flower!
Hello All @PhatPat and @Storm
Would like to flip to flower to in the next week, but I see a couple of issues that I think I need to correct before doing that. Notice a couple of the ladies look a little yellowish to me and several leaves have some brown spots that I think indicate a deficiency of some sort. I Watered Wednesday, water at 6.5 ph with silica added. Top dressed with Down to Earth 444, kelp,Alfalfa and worm castings. After watering added 16oz of water with Recharge to each plant. I am due to water again tomorrow. Your input is greatly appreciated! See below.
Some nute splash here and there looks like. But will take a bit to see results. Depending on how strong the life is. 1 thing with living soils is keep the life solid the plant will follow. Dont overwater just because living soil needs moist. Better to dry them and recharge than drown them.
Thanks @Storm , then you see no reason not to put them to flower next week? Was thinking of adding some cal mag next watering what do you think or should I just hold up on that idea.
Personally i would wait. Let the nutes get ready. When you flip she will need all she can eat for a couple of weeks of stretch. Silica. Calcium. Some N. After stretch she will turn on the pk crave. Couple weeks. I know you want to get going but you will be happy flipping solid healthy plants.
Thanks @Storm
