hello

i am growing in DWC and am 4 weeks into flower right now and im beginning to show signs of minor root rot for the past week or so....growth is still noticeable however some leaves are yellowing in a strange and weird way and i suspect the roots are to blame

ive been using a regimen of 2 tsp per gallon of hydrogen peroxide but it doesnt seem to be helping the roots

i was planning on using cannazym next grow for healthier roots but my question is can i begin using this product now in hopes that it will get my roots healthier so my plant can finish? or is this a product that is only effective if introduced early in a plants life b4 root rot becomes apparent

also a sort of related question....are hygrozyme and cannazyme basically the same things? aka do they perform the same functions and if not which one is better to get
