Hello im having trouble with the ph, i think my plants are having nutrient deficiency related to the ph being to high in my rootzone i was usually watering with PH 6.3 and TDS of 900ppm.
My medium is 50%coco 30%perlite 20%wormcastings.
Temp and RH
Lights on is 27C 60-70%RH
Lights off is 21C 60-70%RH
Then i noticed the deficiency so i testet my runoff.
I watered with ph5.9 and 900ppm the runoff was 6.6 and 1900ppm.
In order to lower both PH and PPM i stardet to water with lower PH and no nutes.
I watered 3 times since then here are the outcommes :
Has anyone ever seen that or even heard of it ?
I dont really know what to do.
Thanks, Happy Growing
