the leaves are down

Ganja reaper ph can depend on media I grow in soil and the ph range has a lot more scope/range than coco

Ganja reaper ph can depend on media I grow in soil and the ph range has a lot more scope/range than coco I think if he fixes his environment problems first and watering he will be able to figure out his problem quicker

Humidity is elementary dear leafson xD

and yes they indeed have some low humidity, 45% is to low for growing stage, raise it to like 80-85 if you can :) ( i like 90% haha, love to see the mist )

You have low humidity and plant has light stress. Raise humidity raise the light or dim it some.

I pretty much agree with @ganjareaper, on this one with it being overwatered. You may still have issues from incorrect ph earlier also. I would personally keep ph between 6 and 6.5 in allmix. You want the top inch of the soil dry really before next watering. Your Ec looks good. Try and get about 20% runoff from your next watering or feed and check its ph and Ec. It should be fairly close to what you have been giving it.

PS i saw you have a PH level of 6.5 and saw a grower telling you to do that in your previous question Well thats better then the 7.5 you where doing but still to high. In my opinion it should be 5.8-6 in growing stage. The nutrients your plant need the most are working well at that range. 6.5 can be done as well but thats more for flowering in my opinion :)

You have been overwatering them to much. Leafs will look like that and get yellow collor Your plants love to get some (N)itrogen but since your pots are full of water it can't ''breath''. Try to lift them from time to time to feel if she is heavy(full of water) or light. Try to give it some (N) nutrients as well.

bcs you water to much it seems... try only watering when the top soil is dry.
