<span class="link_user">@ScotlandDrGreen420</span>, oh yeah didn't noticed , either ways man , from my experience and my basic knowledge , flushing should affect lower leaves first and not by sharping the edges , curving them and burning the tips ; but by taking away the color since the plant is " eating " the nutrients from their leaves; hope that helps , but I might be wrong since I have never had any experience with hydro grow and could be different maybe.
any ways , hope your grow goes the best way possible :grimacing:
<span class="link_user">@KushyLou</span>, they're looking really frosty , congrats!! take care of how the leaves are curving up and getting sharp edges and burned tips ;
im not an expert, but from what I have experienced check the light your giving and the nutrient build up in the soil , maybe is to much and the plant can't take it , or also might be a molybdenum defficiency , or even roots problem , check this page I use everytime my leaves start to get different ;
