Hey guys two of my plants have almost yellow colour new growth. Usually new growth is bit lighter than matured leaves but these look almost yellow and they have had enough time to mature as well. What's the deficiency? Nitrogen?
Doubt you saw any damage from potassium from an extra feeding or even a hot feeding. You're describing nute burn from nitrogen. So is this super soil or something?Yeah seems like that, some other plants also had a potassium deficiency then after adding extra some got burnt tips so didn't want to add anymore for these. This soil seems pretty unbalanced :(
Yes the soil seems pretty compact, I even tried the chopstick method to loosen it up a bit. This is just pure potting mix with compost, no perlite even because they didn't have it. Yes the PH is around 6.5 in the run off. I have only added the seaweed extract fertilizer before this and only once I did that. But from the looks of it now I feel the roots haven't spread enough in these few plants because the other plants which are thriving don't have a nute problem.I am curious about your soil. How much aeration/perlite is in your soil? I thought it was coco for at a glance. Doesnt look fluffy and happy, looks kinda compact and crusty. Just curious, as it may not be a single issue causing your symptoms.
What is your water like. Ph, hardness, alkalinity? You ph'ing your feeds after adding nutrients to h20?
Repotting seems like a good idea actually. But I want to ask is it ok to break off the old soil from the outer edges of the root ball and change the soil? Will it cause damage? Because I mixed coco coir to the soil mix for the newest plants and its very Spongy and soft with excellent drainage, so thinking about Repotting with that soul mixPics of the good ones?
Don't make any drastic moves or pour shit on them yet. ;)
You may just need a transplant into excellent soil. Or an inert media which you will try to manipulate. promix/ coco/ etc...
What is the actual ph, and ppm of the water you are giving them?
Stop spraying too. Research IPM, I do potassium bicarbonate, neem , kelp, and bti outdoors as the 4th stage of the ipm.
this is likely. I have had nitrogen lockout after accidentally nuking my plants with tiger bloom.
dont break anything off, use a bigger pot and do it gently.
and only. transplant if there is enuff root mass to hold the ball together.
I looked at the pictures again. alot of soil there. transplant may not be the way to go at the moment.
looks like there is a lot of room at top of the pots. perhaps top with a rich soil with lots of perlite, and water in.
I would slurry test your soil for ph and ppms b 4 i did anything tbh
