Hey bro! 👋 It looks like the plant is generally unwell. The leaves are thin, there's discoloration and necrosis. A lack of cal/mag in the watering is causing overall malaise, and a deficiency of nitrogen (N) prevents the plant from fully converting chlorophyll. Your symptoms could also be due to insufficient lighting in the growing area. Measure the light intensity with a lux meter around the plant; if the readings are below 2000 lux, then increase the power of the lamp or lower it closer to the plant, aiming for between 2000 lux and 20000 lux for its age! 👌😇👍 Good luck, bro! 👋

Haha that was easy im not up to day with technical smart phones lol. So with 2 sf 1000 on 18 inch there was about 40 k switched off one move one one middle about 18 in is from 16-19 k lux. We will see how they will respond soon. Im sure it was not less then 2k anyway as sf are quiet strong good lights. Thank You again. We will see if it will sort issue. Cheers

Bro, I will save you! ✊ Do you have a smartphone? It has a light sensor that rivals some lux meters! Download a free app from the market, clean it well from dust and dirt on the sensors (screen), measure, and you'll find out! The app is called "luxmeter"! 👌😇👍 Good luck, bro! 👋
