Overwatering under watering or nutrient lock out

[Atlsfinest]

Okay guys so I’ve finally installed my ventilation in my room. Have a intake and an outtake. Intake is brining fresh air from inside the house into the grow room , outtake is removing old stale air from grow room. Just transplanted my clones from qrt gallon pots into 3 gallon pots on which I will flower in. Transplanted into promix hp fresh bag of promix. Now I didn’t flush my clones before transplanting them into the 3 gallons so the medium would be HOT…. Transplanted they then watered them in with nutrient solution but didn’t fully saturate due to the roots not being established in the 3 gallon pots just yet. I probably watered with little under half a gallon of nutrient solution water Ph 6.1 EC 1.8. I should of just watered with PHd water at 6.0 but I went and did nutrient solution. I’m now having issues with my top new growth clawing and it’s just the top new growth. The old growth is fine doesn’t seem to be clawing… just wanting to see if I did overwater or could it be N Toxicity or what have I caused here please help! Much appreciated guys.

Feeding plagron terra nutrients
Medium Promix HP
Temp 76-78F
Humidity 60-65%
VPD .8-1.0
Fans circulating air just fine so don’t think it’s wind burn

Fan leafs so seems to show a little yellow could be transplant shock or ? Deficiency or nutrient lock out ?

Definitely looks to me like some nute burn symptoms in some of your pics, so you could be right about that. I'd check runoff EC to get an idea of where that is. Also, when I see edge curling, taco-ing, and inter-veinal yellowing, I turn my lights down.

Haven’t fully saturated the pot it’s only day 3 so far will have to wait so I can flush them then check my run off but yes I should of flushed them before transplanting in 3 gallon pots. I have turned my light back 10% they’re running at 15% and pulled up to the highest point

I may just be too high but pics 5 and 7 kind of maybe look like possible pm forming and/or bug damage? I would just give a look for good measure but it could just be me

Mag and light intensity.

Def no pm and no bugs I’ve checked

dial everything back turn those lights down and flush for 3 days.. Curling leaves dont typically mean a calmag blast is necessary but wouldnt hurt to do prob.. You gotta ease into everything dont go full send right away do half blasts of light/nuts whatever scale into it

Yea started flushing today took some readings and ph was coming back 6.9-7 and ec was 4.9 ec. Ph going in was 6.1 and ec was 1.8 but I also didn’t flush my plants before transplant so medium was hot to being with then I feed them full strength should have done half

 

[mjvdet13]

Right on. So get that ph down to 6 and if you flush once a week and are using the recommended nute levels then your EC shouldnt be the underlying issue (also swampy pots can do a bunch of weird stuff so make sure they get dry all the time before new water).. I'd start peepin the light situation. Always remember with lights that adjusting their height is typically better than adjusting their power levels so if you have a ppfd reader and ceiling height then move them up 6"-ish.. This all depends on which week you are in as well..

Simply overfeeding that's it... cut nutes back to 50% dosage and use water only every other feed

Upwards curl/canoe always means calcium.


I wouldn't take advice from cannabis nute manufacturers let alone the victims.

Do you have a source or any reading on this, can you explain?

I see my leaves curl upwards sometimes, it always goes away but I would like to know more about , why?

Upwards curl on edging usually means an over feeding... if plants look healthy but lighter in green coloring... usually light is too close...
Purple stems is a tell tale sign of calmag deficiency

What do you think of my new growth

Hope I’m not hyjacking the thread, my apologies

 

[Cannaburg]

New growth looks great... see in circles how leaves look a little wonky and curled.... classic sign of nutes being too strong... still within in good parameters... overall you are looking stellar!!

Sorry to OP...thought I was talking to you

Epson salts cures a lot of issues just a tad sprinkled will help wit ph and lock out

Spraying or in the nutrient solution?
