I dont use those nutes tbh i make my own . But keep pk as is and up the bloom say 1ml . If it worstens . You may be on lockout and will have to flush

It is a two part feed tho . Are you adding the Grow in there aswell ?

Okay will do mate, ill keep an eye on it after see if the yellowing continues.
I initially fed them grow nutes for the first 2 weeks then i switched straight to bloom, i did supplement some grow in a couple of times when i saw yellowing lower leaves.

same thing happening to me mate, Ive given her a lil bit of nute burn so ive back off feeding, last feed was 6 days ago, scared to give nutes as i dont want to further burn but fan leaves yellowing middle of the plant got me panicking as well lol.

Hi guys back again with my other amnesia this time, shes a tall girl spent an extra week stretching, around 5 ft tall.
I saw a little bit of nute burn after i fed a strong solution about 2 weeks ago, so i flushed and re fed at 3.25ml per litre of flower.
The nute burn seemed to stop but fan leaves have started to yellow.
Is it normal for the plant to be yellowing at this stage? Am i over or underfeeding?
Thanks for reading guys any help will be greatly appreciated.

nitrogen deficiency tends to start at the bottom with the oldest growth getting hit first not the middle of the plant yellowing

if it's sativa it needs more grow/N until week 3/5 of 12/12 depending on when stretch stops and how dark the leaves are, it's amnesia so heavy sativa ur in lightMix so can feed earlier

my one is sensi skunk. it says 80% indica but 70% of the leaves are skinny and long on the plant with only 30% looking like true indica leaves.
its either my the nitrogen is not being absorbed properly or its turning into ammonia before absorbing, ive been looking at the nutrient deficiency chart posted up and it looks like i also have calcium potassium and magnesium deficiency, although ive given her epsom salt last week for mg problems.

its very frustrating as it could also be nute burns, 1 thing i must say that looks pleasing growing with coco or hydro is that you know exactly what your problem is, with soil its a guessing game and a painful one
