Thai Sativa and Various Indica.

I ve to transplant my garden lastweek and local shop ran out of perlite therefor i need to improvise. I ve used coco with big chunk coco before with good result but somehow big chunk coco brought some insect with it and evetually kill my garden. This time i only use coco and petemoss but i guess no succeed. After few days i notice root seem to be sufficate so i went outside my area to get perlite and switch the medium one more time. I ve lost one week due to fucking up tried to improvise a mix and another week to recover.Most of them re stressing from changing the medium. I strat giving them nutrient a bit late at week 5 , they re bit yellow. I already give just under 1k ppm, i ll check out how they doing in few days. The outdoor seem to be doing fine apart from being hermies, i ll remove him soon. Edited : it wasnt the moister of the soil, its the coco dust which when i water it actually flew and caught up under their leaves. As i gave too much light therefor they re short and part of them actually touch the ground when i transplant. Those coco re moist and my ventilation is really poor so fungus developed and suck out those leaves till they die, I ll move them outside where its windy and warm. Maybe i ll leave them all outside untill they show their sex and just keep few mom and flower the rest of them. I ll try to finish my grow space and strat the Fem seed with hydroponic setup within this weekend. I will not miss good ventilation for my grow space.
