Start 2 week flush?

Hey friend, In my opinion,you don’t need to flush organic soil.They are acting like slow release fertilizer for your plants.By flushing,You only wash away minerals like beneficial bacteria and microorganisms from soil.But in your diary, I think your plant have slightly Nitorgen toxicity ( dark green and clawing leaves )due to improper soil pH or excess use of vegetative nutrient.You should adjust your water pH around 6.5 whenever you water.Happy Growing... ✌️
