Nute lockout?

I read pretty much every night! Every article opens up another 2 things to read wo overwhelming! But I've giving it a go! Heres some photos under a natural light

So ill take a little more time to explain my situation as I've been so frustrated.

I started off with stardawg auto flowers potted them directly into a coco based medium.

For the first week I started with 6.2 ph water.

One all seedlings was about 2 inch threw the soil I started to feed half nutes of canna a&b along with katanna roots.

I gave each around 500ml ever few days until the first inch of soil was dry.

My temp has been between 26/29 dc
Rh between 55/60%

I run 600w lumi blacks

Along the way the lower leafs started to get yellow tips and dry out and crumble.

Before I started up I had a post up on here asking for guidance and those steps ive done were recommended on here....

So now im under the impression to fees daily until run off and don't allow to get dry. Would you suggest a ph of 5.9ish?
