Second season from clones

So 4th we of flowering and everything is looking amazing... i had to go to my home two for the weekend and for the first time this run I'm noticing some decoloration on the euforia that is following the greenhouse feedings chart but nothing major... maybe the top dress is taking a bit to get to the roots... I'll try my best to not correct it since this is an experiment to choose my nutrient regime but if it continues I'll have to had something to correct it... from another perspective this plant is starting to show some light stress and some purple hues are coming out on the leaves. I still think is to early for this but this is not happening with the biotabs run neither with mineral ferts on the previous run and they are a clone of that plant... the idea to switch to organic is to improve quality (so this maybe it?) and take me some overhead to look for important things to improve.... All I can say is that has been a great experience from beginning....
