yellow tips is indicative of high n or p, nothing really worth worrying about unless whole leaves are dying.

as for the rust colored spots (i'm assuming this is what you mean by mottling?) and paleness to leaves, that's more than likely a calcium/magnesium issue. cal/mag is a good product to always have and use, regardless of strain or species.

it sounds to me like you need to move up to full strength nutrients. pix would help, i recommend you post a picture before taking my advice, in case i'm off base, or incase your description is meaning something else.

hope this helps!

thanks mate im gonna try and get a picture of it later.

this is about a good picture as my shitty i phone will give!!!! i hope you guys will be able to help

go up to full strength and if you still have problems after 7 days, add botanicare cal/mag according to label.

your babies will be fine

thanks im gonna do that , but also thought id let you know i ph tested the water i feed with FU*K ME over 8 i seem to have an issue with hard water!!!! ithink this could be affecting the nute uptake through the roots, so its ph down in the water from now on and hopefully the nutes will start gettin supped up

update???

yeh the water was incorrect ph but with that sorted ive got fucking mites!!!! the joys of being an indoor gardener theyre barstards im into week 5 flowering and they wont go. im using PEST AWAY every two days at the moment and they seem to be under control (who am i kidding) well there arent as many as there were. Lesson always check Ph and for mites at least every week if not sooner. ill post some pictures of the girls in the next couple of days
