Gsc auto yellow leaves

Nethermanstarted grow question 4y ago

Hello, my gsc auto is currently almost week 12 (8w flowering) I'm giving her 'food' every watering and her leaves are starting getting yellow from the middle. I thought it's maybe because too much fertilizer so I water with only water few times but no change. Light is 100w 100%

pH around 6-6.5 I don't have equipment to measure EC or PPM. I'm using plagron fertilizer terra bloom and they recommend using 5ml every 1 liter of water sometimes I'm also adding little bit of Cal mag 0.8ml per L . Recently I changed dimmer from ~80% to 100% light is 60cm above plant

Leaves are turning yellow during flowering - is this an overwaring issue?About 1,5 week into flowering the leaves have turned yellow, especially on the outside. The leaves in the middle are still oke, lower older leaves are dry. Could this be overwatering or something else? I gave around 1L/day, coming from around 0.5-0.7l/day the week before.
