Problems with some of my ladies

[beckerjeremey29]

Good evening everyone. I'm having problems with some of my plants. Some are curling downwards and all the troubled plants have wrinkled leaves. I am growing in ffhf and using general hydroponics maxigro. The soil pH is testing high around 7.7 - 8.0. When I first planted them, the soil ph was around 6.0. I need your help because I don't know what's going on. I don't believe I'm over watering, but I'm not 100% certain. It could be the incorrect ph causing the issues or a combination of both. Any advice is much appreciated.

Looks like water stress and possibly too cold.

Your pots need to be lifted off the ground somehow. They won't drain and dry properly and the roots will get cold.

Stoo feeding them, there is nutrients in the soil already.

Nitrogen tox for sure and too much light. You probably need a good flush then tilt pots on a 45 degree angle to prevent symptoms of overwatering, very low light for a week and then reevaluate

Thanks everyone. I thought happy frog was very mild? The room gets to 85 with the lights on. I would like to do a flush, but last time around, the flush set me back two months. What about just watering with ph adjusted water to bring the soil ph back into range and let the plants eat up whatever nutrients are remaining in the medium. I will definitely grab some bricks to raise the pots off the ground as well. Also, i do have a dehumidifier running constantly to keep excess moisture at bay. That also is helpful to the plants by helping draw excess water from the soil too right? This is my second grow so I'm still new at this. Thanks again and happy growing.

Up to you but if flush then tilt the pot like i say for a min so you dont get overwatering symptoms. And very important to raise that light way up

Why raise the light way up?

 

[Aqua Man]

Why raise the light way up?

Because light drives the plant and the more intensity the harder it drives the plant and the more demand on it.

It not a good thing for a struggling and stressed plant because it cannot keep up with the demand

Gotcha. I'm probably going to have to do a slurry test so I can get the soil PH and soil PPM.. Then once it is confirmed that that it is AA nitrogen toxicity alone and not a ph issue and nitrogen toxicity combined, then I can proceed with a flush. I was hoping to put all my ladies into flower within the next two weeks to a month, but I guess I'll have to wait longer until I the issues are fixed, the plants grow and catch up with their neighbors, and the males are weeded out of the group. Thankfully the majority of the girls are feminized.

Slurry test ppm wise is not an accurate measurement of nutrients in a soil with organics.

Ok. What is an accurate test?

A soil analysis but you dont need it. Just flush, tilt pots and back the light off

Just finished the flush of the ladies that had severe nitrogen toxicity. The others seem slightly overrun with nitrogen, but I think a fresh drink or two of ph adjusted water when they are ready should do the trick. The soil ph for the sick plants is high, so I'm hoping the Flushing and watering with ph adjusted water will bring the soil ph back into the 6.0 area.
Will it be a problem if I leave the plants tilted overnight and then fix them in the morning?

Thank you all again for your help and advice.

Nope thats fine.

Did you add any lime to the soil or amend it in any way?

 

[beckerjeremey29]

No lime. I don't want to amend the soil any further until I can get the ph from from 8.0 back down to the 6.0 range. Your supposed to use lime to make your soil less acidic correct? My Soil is on the alkaline side and and I'm a little hesitant on using Sulfuric acid or any sulfur compound to make my soil more acidic. Especially since I have no experience using using sulfur or aluminum sulfate, etc.
I was recommended to use white vinegar or Apple cider vinegar to lower ph, but from what I've read, those additives are not a permanent fix. I'm attempting to make my soil more acidic by overcompensating using more acidic PH adjusted water. What method(s) would you recommend to bring my soil back down to the 6.0 range Permanently? Keep in mind that I am an novice. Lol

PH drops kits are cheap off Amazon. You def want to PH correct your feed water to 5.9-6.0.

Flush then see how things go what is your water source

 

[Aqua Man]

No like taises Ph aluminum sufate will lower it

I have some young girls who have a similar look, turned out its was all light intensity,, I couldn't have had nitrogen overload because I had not fed anything since soil test and ph was good, i grow in a soil i compost myself throughout the year and what I start out with is a little nitrogen rich at first but if the ph is right that goes away after the big growth spurt, and I usually will have to feed some during stretch. and of course feed again a few times during flower. I use metal halide during veg with some 5k led thrown in as supplemental light, these new led lights that are great for vegging because of the low heat output can be a little inconsistent and light height is critical for the strains I grow , they dont like the light intensity of the 5k high lumen leds.

I've got to get the ph right with a couple good flushes and wash away the excess nitrogen. After both those objectives are complete, they should start growing correctly again.
