WOW another 3 weeks...im really in for it on my first grow lol. Not complaining really but dang! Ok yes the grow nutes has more nitrogen and as specified on my grow chart it shows cutting way back to almost nil. From what i understand during flower and bloom we want more potassium and phosphate? Lmao when they were babies oh yea i thought the leaves were so big! Now starting to really get things going! Thanks ArmanidogI would say another 3 weeks of vertical growth if they are 3 weeks old. You can feed both the growth and bloom nutes together if they have started putting out flowers. Use 1/4 strength each to make 1/2 strength nutes. Watch the tips of the leaves and if they start curling down cut back on the growth nute (I assume it has more nitrogen than the bloom nutes).
They will probably grow another 15-21 inches (38cm-53cm) if they grow a half inch to one inch per day.
Remember when they were tiny babies?
