My plant is yellowing

So what’s guys I’m a newbi I grew northernlights last year no problem this is my second grow

I’m growing (gorilla glue) this time and many problèmes are surging at the same time just wondering If anyone can help me diagnosed what I’ve done wrong or what needs to be done

1- I topped the plant at the second node
2- immideatly transplanted it
3- then used a tea thinking it was nutrient difficient then I added soil enhancer in and boom (marphyle)
After adding the soil enhancer the edges starte to “burn”
Feel like there burning and dying !

You're looking at advanced potassium deficiency. Now to find out why. Potassium is easily blocked by multiple individual nutrients.

Tell us about your medium and your water.

Well first off try and have at least five to seven day intervals between intense stress like transplanting and topping never do both at the same time, you prolly put her in to much shock, she didn’t want any food and after she started to come out of shock she took up to much nutrient that you provided and got locked out honestly I’d use some plain water for my next two waters remove any crispy leafs and see what they look like in a few days a week maybe

I’m using promis hp
The first plant is in promix hp 2 Tbl spoon of magnesium phosphate , kelp meal , and alfalfa meal / gallon of medium
Then 3 tbl spoon / gallon of 444 all purpose
And I made a high in (p) tea for the plants
Tomorrow I’ll go check my ph tester juste In case

Your medium sounds good what temperatures do you run and humidity, what’s the light source? if you used that to build your medium and you use teas do you top dress it or just use the teas? I would top dress with a cup of the 444 and some lime to help with ph and plain water

The is 44% and temp is 23.9

Try bring up your humidity to around mid 50s to allow proper uptake of all nutrients in the plant your temp is good but humidity is low if you can’t bring it up with a humidifier still ray the sides of your tent with water it’ll raise the humidity

seems like the magnesium is too high. It will directly compete with potassium for uptake. Magnesium is present in tap water and usually doesn't need to be added. Try cutting out the magnesium next time you feed the plants.

Thanks so do I just leave the plant and the soil do their thing or do I flush it ! Because the yellow one is not getting better but the first tiny one is getting better I can see new growth and the color is looking a lot better !

Perfect thank you also I can raise it up It goes from 44 to 66 during the day I bought I humidifier will definitely be using it !

If the first tiny one is getting better just leave it, try a light flush on the second one.

Try to not get that much fluctuation. Plants like a nice steady environment, not the constant changing. Try to keep them within 5 of each other for instance if running 64 percent during the day try to keep it within 5 percent of that at lights out no lower than 59 no higher than 69 same with temps. You’ll get it just stay at it, it’s a learning process

It is bro I rememeber my first grow no ph no nutrient enhancer simply water a light bulb some Gaia green green barely any ventilation in a closet and no complications but my plants where northernlights heard it’s a beginner strain so in general the solution for these plant now in my opinion would be let the medium dry out then go get my ph meter calibrated “ do we have to alway water our plants till runoff

I grow in a living soil, large fabric pots and I water each plant based on volume of soil. But no I don’t water to runoff just what I know will cover the whole medium thru the pot I use 1.5 to 1.75 gallons per pot I use a 40 gallon fabric pot watering at the least twice weekly

I'd just keep them moist with plain water and let them be for a couple of weeks.

Magnesium toxicity can cause potassium deficiency.
