Good morning tgc

Can any of you help me out?

Top of my big skunk 47 auto is yellowing.

Is it light burn or deficiency?

@mellowed that's what I thought.

@GoodBudgie it's about year and a bit old.it's only had about 8 weeks use in its life.


I move lamp up and see what that does. As you see its cfl. 300w dual.

It was about inch nn half I move it up to about 3-4 inches.

Thank you @mellowed@GoodBudgie

@uk percy outside, yeah give her a week and see how she does with the light a bit higher.

 

I'd be tempted though to top her/cut off those stressed bits to get rid of the damage and let the plant put its energies into growing the other buds on her as opposed to trying to repair herself. Plus wih damage like that, at this time of year, it could go rotten pretty quickly and we don't want that to happen.

 

Shame like, because the plant looked set up well for some nice buddage.

 

p.s. you have got a fan blowing over the tops?

Nowt to do with tops which i think is caused by light being close as said by the guys, but i think the rest of the plant looks like it`s been a tad overfead as well.

It would set her back probably less time than it would to recover from the burning/light stress.

 

Have a good check over your bulb as they are fragile things those CFLs and it might be damaged.

 

how long....!, sounds like its not an auto then, which does happen as they're not all 100% auto-stable.
