Hello, this problem has been developing with my plants over the last couple weeks. The strain is Sensi star, growing in Flood&drain hydro using general hydroponic nutes. I know that sensi star doesn't like high levels of nutrients so i've been watering down the nutrient solution but im a bit worried i may have over/under done it. The obvious signs of over-fertilization are there ( curled leaf tips) but then alot of the leaves are turning pale green, almost yellow. When toping up my reservoir, i normally add about 20litres with full level of flowering nutrients then add between 1/3 and 1/2 the amount again but just with plain water. Im using 2x 400w HPS, one of which has a heat shield which doesn't seem to make any positive differance compared to the one without. These are roughly a month into flowering, this wasnt a problem during vegative growth so im pretty sure it has something to do with too high nutrients but just need some other opinions Thanks.
