once you get those nitrogen claws they seems to stay with the plant until the harvest.

let the weed thats how my lemon stinky was like all through the veg and flower period..it should take a week or more extra as those leaves may not open again.

Sorry to hijake your thread mate. My plant is exactly the same. Clawed leaves an bottom rounded leaves gone yellow. Would more feed put this right with a high nitrogen concentration help this?

i dunno what to say as i think adding more nitrgoen will slow flowering down all im going to do is go up 0.1 ec until it stops or i get burn

It does look like the tops are suffering from too much N, but the lower leaves just look like they are ageing. They are the furthest from the lamp so they'll not be getting very much light, if they can't photosynthesise they're no longer any use to the plant, so the plant will just draw the nitrogen from the leaves, and the leaves will consequently yellow and die off.

What are you feeding?

if them claws stay there it mat just be me under feeding due to me cutting back fingers crossed they fix up :)

Im a coco grower I had a slight nitrogen problem just keep everything the same add the tinyest drop of nitrogen to your water bottle and give them a good spay just after the lights go off.

I had a simulat problem and thats what i did.

hope this helps.

well my ec is at 1.8 and the leafs have gone very yellow but how can that be when im feeding at a high ec level ? its only the leaves round the buds what are dark green ?

The yellow leaves at the bottom just need a touch of N

The curled leaves near the top could be heat stress related - how long have they been like that and what are your temps/how close are your lights?
