Hey all, I have a problem with my plant - She's been flowering for 4/5 weeks, (12/12 lights for 5 weeks, Flowering feed schedule for 4), in an Aquafarm, using the GHE 3-part nutes. I keep the pH drifting between 5.5 - 6.5, the EC around 2.0, & the temps a steady 26° at lights on, 19° lights off. (3x400w hps) Res changes every 3 days, with topups & adjustments daily.
I've also been adding Hammerhead pk 9/18 & carbo-load for the last 16 days, to try & max the buds, but over the last 2-3 days I've noticed the leaves have gone a bright yellow colour on the plant:
around 40-50% of the leaves have gone this colour, they haven't dried & still seem ok phsically, but obviously I'm doing something wrong here -
I keep 25l of rested water in the res, mixing the nutes up as per the guidelines from ghe, to give an ec of around 1.7. Then, I add the Pk 9/18, (50ml) mix, & add the carbo-load (25ml). This gives an overall ec of about 2 - 2.1.
Can anybody guide me in the right direction, I'm guessing the plant is getting too much of something, but as I'm a noob to this lark I can only think that maybe cutting out the hammerhead & carbo for now may help, as this was the last change I've made... Or would I be better flushing the plant with plain water?
