so i had another thread that i figured out i had nitrogen toxicty, i flushed them all last night after i noticed how iffy the leaves where looking. the 2nd picture shows the like dried out area on the claw and the first picture shows shiny leathery type spot which is now gettin the dried look too. I just wanted to confirm if this is n toxicity? also i am sure from the pale color that is new, they need food after the flush but i did it last night so i dont wanna over water. input/ advice to keep these going please

May i ask what size pots your using? Possibly rootbound?

This is still a baby.. stop flushing babies! Its not a big problem. I would consider this a growing pain for the plant.

I plant directly into 10 L pots only root stim for the first 15 to 20 days then slowly start some feeds. Flushing is considered a last resort since i killed a plant by flushing.
