About nutes, when to change to bloom

[geegee2]

Hi all!! Very quick question..

First time growth, 2 girls, autos, just soil (should know better for next time, too much water retention!) one is 23 days old, the other is about 18 days. The big one showed her pistils about 3 days ago, the small did yesterday.

I hadn't used any nutes until 4 days ago, that's when I gave them both about a 50% dose of hessi TNT (growth); Though I have used hessi supervit from about day 5.

The soil is drying up (Thanks Jangel) and tomorrow is gonna be water day. Thing is both have pistils popping, so they've entered (I believe) flowering. Should I water tomorrow with the bloom complex or should I still be giving them the TNT growth dose? If so, until when??

Thanks a lot!!

When the tops are not creating new node after node of just leaf, but rather are pushing out pistilate calyx, the plant will be at about the 3rd week of flower, and will want large amounts of P/K. You should give them bloom nutrients at or before this point.

Thanks 69!

BTW, anyone would know from personal exp when to switch the blue CFL bulb for the red CFL, given that the girls are just starting to flower?

Thanks

at basically the same time you start giving them bloom nutrients. The plant uses P/K to make buds, and more efficiently uses red light to make those buds with. So you switch to bloom nutes and red light when the plant kicks into full calyx production.
