my baby is ill can i get some help please

my babys ill can i get some help please, its a 4 week old baby big bud, i,ve been feeding it veg food and root feed at the rate it says on the bottle but the last few days its started to look like this

any ideas what it is and how to fix it please?? maby giving it veg feed and root feed is to much for her??

cheers

re pot that plant give it some room to grow

...and it looks like it may be too hot...?...you can always back-up on the nutes allittle...my LSD plants get burn easy, I have to feed them 1/2 strgth
good luck

was planing on doing that today..i dont think thats whats wrong with it though the light its under is only a fluorescent light and the temp right up close is only 28c below that its around 25c so not so sure it is that

She needs a bigger home. This could be wrong but looks like magnesium deficiency to me.

rowlman was talking about the feeding of the plant not heat from the light , i agree with him as well back off on the feed

thanks guys have just flushed her with fresh water and will give her a few days with out feed then cut back on the amount of feed shes getting, my local shop is not open till monday but come monday morning shes getting a new big pot with fresh mix of soil,

will the burned leaf now die or will it regrow? should i cut off the dieing leaf??

it will put on lots of new leaves let it do its thing it will be OK

ok cheers mate will update you all soon
