When to change cfl from veg to flowering spectrum?

[Dr. Babnik]

Dear experienced horticulturists,

I am a student of indoor cannabis cultivation and you gentlemen are my professsors. I am sitting humbly on mu knees by your feet, concentrating on the lession you give me.

I grow autoflowering White Widow and Super Skunk under 250W cfl. This is my first horticultural experiment that does not involves tomatos and chillis. I like smoking to much and plan to be self supplied.

At which point in flower development are one supposed to change to flower nutrition?

How do I decide its time to change from veg sepctrum to flowering spectrum?

First of all welcome to the site! Plenty of info here.

I'll let the autoflower experts answer this question. I am curious as well to the feeding schedule of autos.

What light cycle are you running?

 

[Dr. Babnik]

The light cycle I use is 18/6.

Unless other advice is given, I water when 1 in top soil is completely dry. That would be every 5-7 days. Feed in every other watering. Both feed and feed-free water is supplemented with Hesi Root Complex and Hesi Powe Zyme.

I have different fertilizers:
Canna Vega
Powder feeding from Greenhouse seed co.
Hesi TNT

For now I have fed the girls alternating between Canna and Powder feeding. I will stick tonthe Hesi system from now on, using Powder freeding from time to time, as it has some extra Mg added to i.
