DWC GDP x Solodial x Lemon

This week has been a bit of a balancing act and also the removing of the larger plant, I am growing with reg seeds and it began showing sex a week before the smaller plant. I took a good thorough guess from my previous knowledge and removed the larger plant as it was causing some nutrient issues. After having a 900ppm reading I got a reading of 120ppm after 5 days. I noticed that the leaves were displaying copper deficiency signs most likely due to PH issues. I also added CO2 for the last 2 weeks to attempt to curb what I thought was heat stress. I have adjusted the nutrient ppm down to 850 to try to reduce any burn the plant could be experiencing from the previous 1200ppm level. Sorry there no good photos of this week.
