Leaves Curling and stunted growth

Plants are experiencing bad leaf curl and slight browning at the tips. Suspected too much nutes so they've been getting straight water for over a week now. But I'm not sure if I've solved it and they're recoverable or not, would really like to pinpoint what went wrong. My other theories are the Ph being too low because when I measured the water nutrient mixture it reads at around 4.5-5ph, after the week of just water the soil is reading 7ph though.

Conditions:
Soil grow in Hp promix mycorrhizae, Ph probe read the soil at 7ph
Temp High=83.4f & 41% humidity
Temp Low=66f & 0% humidity
General Organics Nutrients

Im no expert but it sounds like :

"The problem your havign sounds like a standard N tox. Too much Nitrogen in your medium. Or they are staying too wet either one of them or both.

N tox causes dark green leaves and pans to curl under like a "crows claw", common name for it. They will start at the tips curling under and if you keep topping up with Nitrogen the whole leaf will curl under from the center and become really skinny." (copy and pasted from another site)

flush them things real well if your pots have good drainage ,flush them rinse that extra out ,,or it can go into a lock up mode and will not take on water or nutrients and will get worse,,it looks like a pretty healthy plant,,so should recover am hoping ,,flush flush flush if you over did it on the nutrients

I'm leaning towards soil being to wet. Do you only water when needed or?

If you have been over watering let it dry right out and then a light water with Epsom salts.

Yeah, don't water them until needed, wait for them to get light and fully dry. Been growing for about 2-3 years so I've got a system, haven't had this issue before. Was giving them 2gal/watering (just enough for a little run off) but i've dropped it down to 1gal/watering cause they've been drinking less and don't want them to stay too wet.

Sounds like it could be N tox then?

My other question is when do I reintroduce the nutes. Should I just keep watering with straight water or do a full flush and resume at half strength. I'm assuming the leaves already affected won't recover and I'll have to keep an eye on new growth?

These are nuked so bad I doubt they will get healthy again in time for a good flower. If in veg, they would probably take a month or so to correct to healthy growth again. Too many ferts and ph issues more than likely. You shouldn't have to obsess over PH in a soil grow. You mention testing the soil ph, I am assuming this is one of those cheap probe devices, throw it away, probably totally inaccurate and leading you to do things that you shouldn't. You said something about the nute solution being 4.5-5 / this is totally inappropriate. If you feel the need to add acid to nute solution in a soil grow, you only need a little bit if any, nutes should be around 6.3 for soil feeding. You may as well flush the heck out of them and gradually reindroduce half strength nutes in a proper ph range.

Yeah, I've never had to worry about Ph until this started happening and so I tested my tap water which read 7ph and then added my nutes and it dropped to like 5ph, this seemed too low so I grabbed a soil prob when I was out grabbing stuff to double check. I've used these nutes at higher levels than what I was feeding without issue (with another strain so could be more sensitive, but I'm having this problem with all 3 strains currently on the go). I'm starting to think over time maybe they've gotten more concentrated and are throwing everything off, as far as I know General Organics are supposed to be Ph neutral so I was thrown when i found out it was dropping the Ph so low. Has anyone had a problem General Organics concentrating over time?

I have come across a couple fert lines that drop the ph too much. I would not use a line that requires ph up when your water is normal at 7. Again, always double check and calibrate a ph pen as wrong reading can set you back in a major way. In any event, sounds like ph is your issue if you are mixing nutes according to directions.

I look at added Nutrients as a bonus,,,But I build a good soil first,,if you do that job good ,,you will have plants flourish,,I do not give mine anything I mix good soil,,or been lucky,,,soil is the house your plant has to live in ,,it can be a shack or a mansion,,,bye that I mean there are many ,,,and I do mean many living bacteria's microbes and micro organism's these things in the right environment go crazy and live well picture them as the works,,the better they live and eat the better the soil is in return the better the plant will do in good soil ,,like a house build that good strong foundation,,do not rush your plants with nutrients unless needed,,,The plant given the proper soil will achieve the size you want ,,no good way to rush nature ,,give them time indoor grows should not be measured in days ,,,but rather in the plants size and mature ness ,,,,,If you start with a good hand mixed soil ,,you will have a better grow in the sense that you will have less complications or deficiency's later in the game,,when you have a room of 50 plants you do not want to have to make corrections if you can help it a good soil has been my best friend ,,watch mixing to much blood meal or worm casting in a soil less is more sometimes and have seen many become N tox from the soil they will stop being able to absorb proper nutrient and get sicker,,,,I grow my roots first,,I have helped a few folks out with this and if the plant is bad enough have had to transplant and wash the root system off ,,as gently as you can,,but they were worse looking then yours ,,remember good drainage,,,I can water every day if I wish because I have good drainage so it never swamps my girls,,,,I grow my babies in a red beer cup untill 24 inches saves huge amount of space,,and allows that root system to build up always water to the out side edge,,of you pot never at the base of the plants,,the roots will head to the water make them grow ,,no nutrient for babies in my book later I will if needed ,,,these plants have grown for 6500 years that we can prove they like a good soil,,will post my mix,,

Every builder may have his favorite,,,,,I mix a 2 gallon bucket of sand,,2 gallons of home made compost,,,2 gallons of cow poo compost manure,,,4 gallons of Pennington professional potting mix,,and a bout 2 gallons of pete moss,,,I also throw just a wee bit of lime granules in my soil,,and mix it buy hand until it feels very soft,,,,should have good results ,,if any wish to try this,,,,,
PS Lime is not a nutrient but does add calcium and magnesium and 5-6 other things,,,,,,which adds to the quality of the soil in the sense that it helps the bacteria establish a good healthy home ,,which,,allows your plants to use more of the natural nutrients in there own soil ,,and when nutrients are used they benefit more from them as they can uptake more of the food you are giving them,,,,,,,,,Lime can be hydrated and added later as well if it is needed ,,,other things like feeding some Black strap molasses un sulphered,,will also help the soil as it has carbs and other things that the soil eats and improves the soil

Yeah would like to build my own soil but I don't have the space to mix it and let it cook so I use Hp promix mycorrhizae soil and General Organics liquid nute line. They seem to be pretty good, just like a premixed tea. Listed as organic and vegan for what that's worth. Should be a somewhat living soil, I make sure not to use things that would kill off the bacteria and organisms. It def acts like an organic food web, takes a while to break down and get delivered so you have to time it in advance when your feeding. Think I got over zealous cause I'd just finished growing some little monsters that loved to eat but ended up being a genetic hermie and breaking my heart. Went into some new strains too heavy handed trying to replicate the last batch and they must have nuked out on me. Will post some progress for anyone curious in the recovery time from this mistake.
