look at these pics whats your views please yellow crispy leaf tips

im using john innes number one and all i have fed them is balancd water. the next feed in the morning is going to have a dilute dose of nutes. the stuff ive got is canna a+b.

as a rough guide how much water would be sensible, if im feeding them every 48 hours, 500ml, 1 litre, 1.5, litre

water them untill it leaks out of the bottom of the pot and only water them when the pot is light when you pick it up or water when the top of soil has gone dry to touch and eye

allways water untill it leaks out of the bottom other wise u get a build up of nutes and salts in the pot how has it gone since youve gave it nutes mate?
