1st HYDRO - Which NPK would be the BEST for my flowering plants ? (PICS !!!)

High RIU Community,


This is my first hydro grow that I am growing in my closet.

I got a nice Persian Bud (Indica) and a NLxBB growing nicely under a 65W CFL. I use this simple light because it doesnt produce too much heat and so far this lighting system has been easy and good to me (check my previous thread).

However my question comes about NUTRIENTS here.
I grew my plants after 2 weeks on 6.5-6-19. After 4 weeks I gave them pure water for a few days and then I gave them some kind of high PK nute 2-8-12 in order to know their sex ASAP (2 females out of 7 f***ing plants, WTF??).

Now they are back on pure water but I need to feed them with a good flowering nute. I am not in a country where I can get our special kind of nutes easily so I have been doing some research and found some that could be good for the plants.
Which one do you think I should get ?

- The same PK nute I've been using ? (liquid 2-8-12)
- Nute A ? (powder ６-４０-&#65302
- Nute B ? (liquid 4-6-8 )
- Nute C ? (liquid 2-5-5)

I do not have much information about each one of them, I just need to know which one of them would be the most appropriate (considering the fact that I already have the 1st one but I need to buy the others).

What do you all think ?


PS - I only post one picture because I plan to make a grow journal once the grow will be over (I got day by day pictures).

PEACE OUT !

100 Views and nobody from the Hydroponics section has the ability to give me an answer ?
I thought that hydroponics users had more EXP when it comes to nutes...

While I'm at it : If I change the light cycle from 12 hours to 13 hours, is there any risk of stunting ?

OPINIONS PLEEEEEASE !!!!!!!!

Well, honestly I cant help you with nutes. I grow exclusively in DWC hydro setups. I use the GH flora 3 part regime. I have Kool Bloom both liquid and dry for flowering as additives to the GH flora line. I had great results with that. Also you could have influenced your plants to go male because of the low levels of nitrogen. Having higher levels of nitrogen during the veg stage of growth helps with getting more females. Just something to think about next time.

Anyways about your second question. So let me get this clear, you want to go to 13 hrs of light and 11 hours of dark? It wont seriously affect your plants but it wont help it put on any more weight faster. The best photo period for flowering is 12/12. I would stick to that if it was me.

Peace and positive energy to you.

Damn, I did not know about that... Since the plant had a pretty good growth I thought that I had made the right choice.
Thanks for the 411 !

Alright I will stick to the 12/12 then. I have read some other threads suggesting to switch it to 13 but I would not take the risk.

Thanks again Nailz !

nut B looks ok
