changing from 18/6 to 12/12

[latewood]

when you want to change, Add a complete fresh water/nutes change out...
I use 2 different values for GH3-part 5ml per gallon of each in early veg...then 8ml per gallon in late veg/early flower...
2nd to 3rd week of flower...(I mix 5 gallons at a time.)
week 2-3f, I use 15ml grow-40ml micro-40ml bloom)
I add 15ml of calmag+ (I use ROwater)
and I use Liquid Karma 40 ml...remember this is a 5 gallon recipe.

In between changes7-10 days, I add rowater by itself, or with 40ml Liquid Karma.

ph at 5.8 until week 2-3f and then ph at 5.4...5.5...5.6..5.7, and back to 5.8 for the last 2-3 weeks. Hope this helps.
Goodluck

I've read that when you start flowering, the ratio should be 1-2-3 (N-P-K)
Cut off N 1 or 2 weeks before harvest

I have questioned the 24 hour of darkness but always done it, been raised around old schoolers. I have said before on this board that I do it, but I have also said that I am not sure if it isn't a hippy tail. LOL
I don't do the 2 to 5 days of darkness to increase the resin at the end of harvest, I have seen too many tests that said that they had seen or noticed no difference. So maybe I am 1 for 1 on the hippy tails.

3-2-1/1-2-3 is just another option that is being used. Advanced nutrients and GH do something close to what I posted...I just tweaked the formula a little as per my own observation.

I used 3-2-1 in my 1st grow, back in the day, but there is no need and you would have to tweak that too. that is alot of nutes...Also
think of the world when you have a question...common sense...When does the sun turn off for 24 hours?:smokin:

If the sun doesn't turn off, then why would you turn off your lights for a day...Just change periods, and change nutes...If anything is different at transition, then it is the fact that some growers "flush for a week at transition. peace

I was curious about that too. I was considering the "soaked in darkeness" technique between 18/6 & 12/12 but didnt do it, so I guess I'm glad we didnt. We were worried, however about the nute changeover from veg to bloom so we basically flushed with plain water for a few days when we changed over. Then we started on 25% bloom. I've seen many people say to "just go for it" once you get to the flowering period, but I've had some problems with nute burn and we wanted to stay on the safe side. We're having some problems with one of the plants looking severely deficient in something and the others are looking a little sad too (this is in the main flowering room), so we bumped the dosage up to 50% bloom. Also planning to add some epsom salt after suspecting possible magnesium def.

So, questions:

1. Should we bump our bloom nutes up higher to 75% or closer to 100%?

2. Does anyone else think that our plant #13 is deficent in magnesium?

Hey, latewood and bobbong, I've been waiting for you experts to come over to the thread and give me some input!

Dont mean to "hijack" your thread, misk, but I did have some of the same questions regarding light and nutes so I thought I'd add it in here. Thanks!

Be cool.

Again the matter of full strength nutes as opposed to 1/4 or 1/2 strenght is a matter for each individual. I would say that you would want to feed at least 50% after transition, but I personally "go for it!" and give them a fresh batch of full strength EC 2.0 nutes.
