Oh another question (Sorry) Does it mean anything when the bottom leaves go yellow cos dont know if this should happen or not? some say it does,others say its a lack of something?
Can be a number of things, normally means a Nitrogen deficiency, if it continues look for something with a decent N value. Or you can buy N in nute form. However, here is the tricky things with plants, when they show a deficiency it can actually be due to something else. So do an MOT, check PH of medium, give leaves a check out (underside as well (for critters). Give a foliar spray, a good water with asomething that helps with the uptake of nutrients and helps leaves start photosynthesising....stuff like Iron, Zinc, Molybedenum, Magnesium, Calcium, trace elements that are 100% essential for nutrient uptake and plant development.
Alternatively, pull the yellow leaf off. Give the plant a bit of scran/food and monitor.....
