Not dumb Q's at all …..
1st, go and get yourself a small bottle of
Pro-tekt Silica…… (you can get other silicas but I prefer
Protekt)
I use
protekt, not only for plant health but also as a natural PH up.
The very first thing I add to my RO water is Protket Silica, this raises the PH in the RO before adding Magical and base nutes which naturally lower the PH.
So when all is mixed together, you should NATURALLY have a PH of 5.6-5.7 without Ever having to add PH adjusters!
And, your nutes will stay stable for a few days, so if you need to store some off to the side for a few days until next water, your nutes will be fine and the PH will not fluctuate because of how stable this recipe is!
Then, if you get around to it, go ahead and ditch AN's b-52. (or keep it but use it sparingly at half the recommended dose and only once a week)
The Only other things I'll recommend you get is some stuff called Mycostop for root/plant health and some MicrobLift for Fungus Gnat control.
Mycostop I use once, every two weeks, at only .1 gram per gallon! (or 1 gram to every 10 gallons)
So a little bit goes a loooooooong ways!
Also Microbelift I only use once a week and only at a ratio of 1 ml per gallon.
So again, a little bit goes a looooong ways!
This stuff has kept bugs out of my rooms for nearly two years now….no bullshit!
Then for nutes, All i use is;
Protekt Silica
Technaflora Magical
GH Micro
GH Bloom
And I mix these nutes In this order….Respectively!!!!
PH should be no higher then 5.6 to 5.7 max!
EC should be no higher then 1.2
Water each plant "Once a Day" until there is a significant amount of runoff….. there is no wrong way to do this unless they are not getting enough runoff.
If you do not properly water them each day, (water until runoff) your plants will begin to show signs of wrinkled and twisted leaves (signs of PH fluctuations in the root zone) and deficiencies (caused by lock out)
As for your light, I would stick with the MH until your ready to flip, then switch over to HPS.
