Hey everyone, I'm a beginner grower, using 70/30 buffered coco coir with EHG Bottled Nutrients (its a South African Brand). I have 4 plants that I am growing under a Sunraise 1000. To cut a long story short a couple weeks back my plants began to discolour and due to circumstances out of my control I couldn't fix it until now. I'm now supplementing calmag with my nutrient solution but I don't know what to actually fix. Plz help!

Yellow leaves from the base out to the tips is most likely iron deficiency. Here's more info: https://www.growweedeasy.com/cannabis-plant-problems/iron-deficiency
Also, what is the pH going in? and what is the PPM of the runoff?
So earlier today I did a flush with ph 6 water and cal mag supplement. The oh of my nutrient solution i put in is usually around 5.7-6. My ppm pen broke so I've only been able to measure the ph of the runoff which was around 6.2-6.4 for all 4 plants. @Mr. Grow It
@Aidan Kenealy Ok, keep us updated on how they look in 2-3 days or so
@Mr. Grow It Will do. Last question, Im putting my plants into flower and was wondering how long it should take to change the lighting schedule (Maybe a week?). I also have a RED bloom setting on my LED and was wondering when I should turn the light to plain red. Thanks so much, you're a legend!! 🙏👏
