yellow leaves on plants flower week 4

[ash tee]

hi ive grown before a few years ago always used to use canna feed in normal soil now im using canna coco with dutch pro feed i think i was over feeding them at first i was putting 15ml of grow nutes into a 10 litre bucket on veg 5.5ph and as the plants grew increased it to 25ml thats when i noticed yellowing on the leaves i backed off with the feed flushed the plants with ph'd water they seemed better i fed them one last time 15ml of grow and then swithched them to flower so i started feeding them 20ml into a 10 litre buket of bloom ph around 6.0 leaves still yellowing i flush them start giving them 10ml of nutes into a 10 litre buket same effect the leaves are crispy brown and yellow bud growth seems a little slow but generally good heres some pics 292490292491

have you tried flushing them? you may not be able to save the ones that are turning brown on the ends and remember when it comes to feeding less is more I learned that recently with my LA Woman.

def looks like nute burn to me . whats your heat and light height ?

5.5 is a to low 6.5 is better at 5.5 PH you get lock up where the plant can't get nutrients. Even in flower the plant needs N just not much and you should always give them a balanced fertilizer because they still need everything just in different proportions. Flushing them will water log the soil and they drown, why are you flushing them and then feeding them. Try a little kelp extract but this late in the game they don't have much energy left because those leaves that are turning yellow are the power source and when they are gone they're done.

hi ive been reading up online and people say when you over feed them to flush them threw with phd water, and i sit it around 6.2 in the flowering stage what do you reccomend i have my ph when im veging

I think you have more than one problem they are close to being done so if you have flushed them just water them when they need it with water and see what happens because what ever you put on them now you will be smoking later.
