Is this phosphorus?

[Haunts]

Problem: Leaves have a bit of purple appearing, some yellow spots, slight cupping of the edges,

Medium/grow method: Plagron Light mix

Feed: and supplements used: biobizz grow, Bloom and topmax, schedule below in the images

water source: tap

Strain/age: Cream caramel, start of week 8

light used: 150w hps

Climate: 23c / 30rh

This poor plant didn't have a very good start in life (I chopped her head off early on from lst'ing her) so I'm trying to get the most out of her. This has started appearing over the last 5 days maybe, I was wondering if it was phosphorus.

Yes,it looks like phosphorous def so try upping your bloom feed and use cal/mag if you already havn't.

Ha!! I have the exact same thing happening, and took those steps yesterday, by increasing Green Planet Massive to compensate.

:smoking: What's good Haunts? ...looks like I forgot to hit post here earlier ..... You got covered anyway! ...CC does show color as well, so this might be part normal expression as well,...Boibizz is mild stuff mate, so maybe look into a PK booster, right now is when to hit'm! What do you have, or can get hold of?

I'm good Waira, just trying to get a grow where I don't have an issue , I hope you are well?
I have biobizz topmax which I'd started using at 1ml but realised I should be using it at 4ml, not sure if it's classed as a pk booster though? Could the under dosing of this possibly have caused the issue?
I also have some AN Carboload and Overdrive left from a previous grow.

..alls' well enough, thanks! yeah, it's so mild mate, no need to cut it unless there's obvious signs of nute burning,... you're short for sure! You need something with higher PK numbers, whatever you have or can get,... I don't know the NPK#'s on the AN stuff......

top max isnt going to go much at .1- .01 -.1

Overdrive at 1-5-4 is what you want to be using to get caught up in your phosphorus
