HELP! Possible nute burn? AKR 41 days old

Hey guys, bitta help needed!

Afghan Kush Ryder 41 days
Using canna pro+ soil
canna terra flores on half dosage
Feeding 2-3 times a week
room temp around 20-25c
room humidity 40-60
soil ph 6.4-6.9

Posted about a week back when my plant started showing signs on nute burn.
The thread is here:https://www.rollitup.org/marijuana-plant-problems/674680-help-first-grow-have-plant.html#post9240245

Anyway came to the conclusion my soil ph was too high. Since then ive slowly lowered it to about 6.7 and trimmed away the badly affected leaves. Since then though new leaves are being affected and it hasnt really shown any sign of dissappearing. Im getting worried and could do with some knowledge!

It definitely looks like ph was to high. What was the ph at before you lowered and what did you use?

Also looks like nutrient deficient which ph being to high will cause. If the ph isn't right, it will keep the plant from being able to absorb the nutes that are in there, causing an over abundance of nutes and nute burn as well.

Also, how often are you feeding it, and what strength? What is NPK of the fert you are using?

Hey man thanks for the reply.

Ive been feeding it when it needs, about twice a week using Canna Terra Flores (2-2-4)

The ph was around 8, i lowered it to 6.5 over the course of 2 feedings using ph- bloei (http://www.bradfordhydroponics.co.uk/nutrients/house-garden/house-garden-ph-bloom-ph-bloei-ph-down.html)

I fed yesterday and it seems to be getting worse. Should i just flush with ph treated water? Im scared for my babies the trics are just started to take over

No problem. I would stop feeding it for a week and let the soil completely dry out and make sure the ph stays around 6.5. It will take the plant a few days to adjust to this and to be able to use the nutes you have given it. Next time you water, use only regular water, no nutes. My opinion, but am in no way an expert.
