PP shiskaberry coco first grow

DAY 37: I suppose that she has hard time absorbing nutrients because root section is too packed/wet. -Lower part yellowing looks like magnesium deficiency? DAY 38: Couple yellow spots and slight nute burn in leaf tips DAY 39: Trying to raise humidity with wet towel, bowl of water and setting a timer for exhaust fan. (15 minutes ON/30 minutes OFF) Humidity has been under 30% all the time, didnt know that could even cause issues.. ^^ DAY 41: Fixed humidity issues: - Bowl of water with a sponge in it and i setup exhaust timer for 45min OFF / 15 min ON . - RH is now around 40-60%. When fan is on for that 15 minutes it sucks humidity to 25% but not under that like it was before. And it raises fast when fan turns off. So its alot better now i think! Also temperatures doesnt raise too much without the exhaust. Air temperature +3 and medium temperature +2 at time. PHOTO 41 - Color doesnt look this saturated lime/yellowish but its a bit lighter green. Dropped nutes for little bit lighter solution: Grow 1.2 ml/L Calmag 0.5 ml/L
