Hi, any ideas on what could be causing this, this is a indica, cbd nordle and I have grown many times with no problems, it’s a fantastic strain. I am growing just the one with two saltivas behind, cbd medihaze again an amazing strain. Temps are a little high unfortunately at the moment around 23 lights off and 25 28 lights on RH is 45 / 50 lights on and off. The indica seems to be struggling unlike I have seen before and is very behind In this week 6, the tops seem odd looking with the yellow patches. PH going in is 6.5 and ppm is never over 1150 and all feed is the biobizz line, it’s a fully organic grow. Any ideas ?
These are the media haze looking fine
Help please, never seen this before

Heya buddy the yellowing up top is iron Def. Not a soil grower so no idea what caused it or how to fix it but that's what it is. Not extremely helpful I realise but it's something I get in hydro.

I use fish fertilizer to boost them this late in flower. A capful for each gallon perks them right up.

IF that is an iron deficiency it's almost always caused by pH.
But your pH isn't off unless your testing is off.
Could also be light burn.
