Stonerdanswered grow question 4 years ago Try increasing the amount of water you irrigate to about 2-2.5 liters with at least 20-30% of it as runoff, and increase the Grow A&B by 1ml/l each since your plants are starting to show Nitrogen (N) deficiency (slowly increase it and the b-52 as the plant matures).
Other than that the plants look great!
Hope this helps! Good luck and happy growing :)
