Bright yellow leaves

Afternoon all,

Just came back from a few days on holiday to find my smaller plant developing some very bright yellow leaves. I know there'a a ton of info on this forum re yellow leaves, so will take a look myself. The same leaves last week started going purple.

Wanted to upload a few pics of it to show you guys.

hi, its strange how its in the middle of the plant, as you say theres loads of info, i was gonna say mb, but then the purple leaves would point to phosporus, afraid not the voice of experience but the voice of google!!

Purple could be genetics but is generally an indication of a P deficiency. The bright yellow leaves look like the N has been stripped right out of them. Give her some Nitrogen fertilizer aka: fish meal, blood meal, mexican guano, alfalfa tea etc etc. Wait a few days. The yellow should gradually fill in with green if everything else is in order. The plant looks wonderful otherwise.

Thanks guys, late reply I know, but been sans internet for a while travelling.
Appreciate the comments
