nice grow ! sorry to bother you , but looks to me a little Mg Magnesium deficiency looking at picture 4 the leaves on the upper left. I saw because is the second time in a row that I experienced the same issue. IS very light and subltle but in my opinion there is some discoloration between leaf veins..it start yellowish there. Maybe i am wrong but.. check closely those leaves. I know you give Calimagic but some strain are Magnesium Lovers. Led strip out magnesium and low ph due to hydro do not facilitate Mg absorption. I fixed twice with epsom salt diluited in osmosis water final ppm 150 (1gram per 4 liters) as foliar spray works very fast or in the reservoir to. Hope could help hope I am wrong and is only the picture and I am stoned as shit :)) have a nice grow
if you want check my actual grow strawberry lemonade 2nd picture named DAF 3rd week day 22. you will see an healthy overall plant but some leaves has discoloration very light inter veins . one of 2 plant has Mg deficiency . same nutrients organic same everything. just hungrier :)) from now on i will always add mg (epsom salt) to my water. they need at least 75ppm of pure Mg. not more not less :) Epsom salt is Mg ans Sulfur almost 50%-50%. So 150 ppm of epsom i believe is 75ppm of Mg. Starting from osmosis water.
