When to add flowering nutes?

I have two lowryder#2/b.c.mango cross been on 12/12 for almost a week. When should I start using bloom nutes? I have a gallon of organic liquid bat guano, the high phos. stuff. Was going to do this and molasses. Anything else?

Could I start using now, maybe every other week? I have the BUDSWELL lquid. High phos blend of bat guano, sea bird shit and worm castings. Was thinking I might try Budswell for one of the plants and FF big bloom bloom for the other, see the difference?

Is this cross auto-flowering? If so you don't need to ever switch your lights from 18/6 (or 20/4, whatever floats your boat) to 12/12. If your plants are auto-flowering I would suggest switching them back to 18/6 and feeding them a veg nute mix until you see them begin to flower. When they begin to flower then you would switch to the bloom mix.

If your plants are NOT auto flowering I would suggest feeding your plants a transitional nute mix (half veg, half bloom) after switching them to 12/12 but before they have actually begun to flower. When you see your plants actually flowering, then I would switch to the bloom mix.

Of course, if you started feeding your plants the bloom mix now I doubt you would hurt them badly, if at all. Just keep an eye out for nute burn and nute deficiencies.

Cool man. I used FF ocean forest cut with 1/3 perilite. Lowryders don't like a lot of nutes. so I let them go with just water for the veg cycle. Worked awesome, three weeks from seed they were 8"! Thet are crossed with BC Mango and thats it, never crossed back, so they are NOT auto flowering. I understand it takes at least three back crosses to get a lowryder cross strain to be autoflowering. I'll probably start a light bloom feed in week two, as the two females mrgreen are starting to flower!
