Leaves turning purple

Measure the height of your plants during stretch each day with a tape measure. When she isn't adding an inch per day stretch is done. I give N until she stops stretching.

I use all biobizz stuff myself so cant help directly , all mix soil , grow,bloom,top max stimulant , recently started to use bio heaven and root juice too.

You do not need to PH your water with that acid/alkali shit , good soil should regulate the PH for at least one grow cycle , it does more harm than good.

Definitely need to keep giving them grow feed as well as bloom/stims in flower , I keep up my grow feed right until the end......no flush either just less grow at the end.

Obviously if I see any burn ill back off but going with biobizzs own schedule , not had any and the results are stellar especially after using the bio heaven.

Just got an all auto grow on myself after being really impressed with blimburns tangie auto , was a freebie , got 6 x daiquiri lime autos from DP and a gigabud auto from G13 going.

I gotta imagine these plants have been harvested at this point... How did it turn out?
