Changing light cycles

[GreekSoldier420]

I am about to change over to 12 on 12 off and I have a 1000 MH Conversion in an HPS Ballast. Can I change my nutrients to the new mixture for my next stage and then wait to change bulb out till tomorrow? Or will this stress my plantws out? Or could I change my bulb right now in the dark and then change my nutes later this evening?

you have a few choices...

you can change over the nutes anytime you want - but remember to greatly reduce the PPM when you switch to bloom nutes.

if you want some more veg growth - switch to 12/12 but don't switch to bloom nutes for another week or so

so i would say - switch to 12/12 before switching nutes, remember to reduce PPM when you do switch - and you can wait to switch nutes for a week or two after switching to 12/12 if you want more veg growth.

thankyou very much

you're very welcome! I'm no expert so if others chime in with better/different advice - feel free to follow it.

If you can lower the temps in the room at the start of flowering this will get you some nice fat buds. I also agree with email468,, good advice

why do u have to go so low with the ppms when u switch?

When you put your plants into flower (12/12) they are going to stretch, and by giving them veg nutes (high in N) you're going to promote that stretch. So it's your call, by waiting to switch to bloom ferts you are going to have more stretch, I'd personally switch now but alot of growers might disagree.

that's right. so if you can spare the room - then veg away! otherwise switch to bloom nutes. you want to reduce the PPM when you switch because you are switching from Nitrogen heavy to Potassium heavy blend and want to ease the plants into the change.

oh ok, cause we just switched to flower ourselves yesturday & we are at 400ppm.
but uor sheet shows the same dosage for A/N nutes for micro grow bloom as did veg stage.
or am i wrong.

if you are on a specific feeding schedule then go with that - my advice was rule of thumb using any old nutes.

i get what u are saying, but we always hear u should use more micro fro veg & more bloom for flower right?
but the A/N nuts doesnt follow that cause the doages are the same # of oz for all three for both stages or should i give more bloom to help with more budz?

 

[infamouse21]

also i was told the bud blood will burn the hell out of the plants if your not carful is that correct? cause my hydro store told me not 2 use it till i grew a few first but if it is that good i want 2 use it, i wont over dose start small them go up

again - if you are using A.N. i would follow their recommendations.

if this is your first grow - expect to make a lot of mistakes -- just start growing and start getting that experience under your belt.
