Burn, deficiency, stress or what?

Hey there guys,
I need some advice. I can't, for the life of me, figure out what's wrong with my baby(white widow auto). It's the tips of leaves are yellowing and it looks like burns but doesn't look like any other picture I found on forums.So this is what I've done with it recently:
-Transplanted into an 8 litre pot (and it took it like a champ with no sign of stress) I'm growing in coco-perlite + 20% vermicompost and I sprinkled some azomite in the transplant hole
-Kept giving it ph corrected mineral water (same water as before)
-the bottom most set of real leaves were getting pale and yellowish so I fed it some nutes made for bamboo plants, they are similar to veg state nutes (3 days ago when the plant was 15 days old) (yes I know I should feed it cannabis nutrients, but in my country those are so expensive, it defeats the whole purpose of growing)

-and that's when the burn-like yellowing started, even though the bottom leaves are now a lot greener(pictures below).

Can you tell me what's wrong? What do you recommend I do to fix it? Thank you guys

Anyone?!

Reckon I should flush it mate?

What exactly did you feed it .....and I personally do not recommend you flush .....if I were you I'd give it just water and make sure it is completely dried out before you water again ....the new growth looks like the tips burnt almost immediately as well .....that would be my plan of action .....GL

I fed it high nitrogen npk. 20-10-15.
I reckon I should water it then. It may stop the burn from spreading. I think I'll add reaaaaaly small amounts of fulvic/humic acids to help nurse it back to health (maybe 2 drops per litre). What else can you suggest?

Don't add anything at all .....just give it water .....that plant didn't need anything yet ....just give it plain water the next few times .....when you do feed it again .....a very very very very low dose per gallon .....what are the ml per gallon your food recommends?

We all make mistakes and that's how we learn .....remember these things grow in the wild without our help at all ..... Better to have to add N later than have this trouble ....like I said it's how we learn ......there is such a thing of killing with kindness.

You, much like your mentor, are a wise man. Thanks for your advice and for the wisdom you, so generously, shared with me.

Assalamu'aleikum bruv.

Check the label on your nutrients. My guess is they little or no calcium and/or magnesium. Growing in coco you will need to add a supplement of these.

I put crushed egg shells in there, I thought that would fix it. I'll look into getting some cal mag. Thanks for your insight

Egg shells take quite some time to break down. You will need to add supliments otherwise.

Yeah a bottle of calmag will make your life easier growing in coco for sure. I like Bonticares calmag plus.
