This is my first grow and I'm having trouble. Everything else is dialed in, so I think it must be related to the daily 5.6-6.1 pH swing I see and/or the pH down that I'm constantly having to add every single day.
My plant often looks droopy as if it's not getting enough oxygen (which it is), various leaf tips curl either up or down, and most of the lower fan leaves have some degree of brown "rust" spots which point to some type of deficiency.
I'm running out of ideas and my only guess at this point is that one or more nutes are getting locked out once the pH down/phosphorus in the res gets too high??
I'm going to change the res in just a bit and see if she looks any better in the morning, but I'm desperate for any input at this point if you have a minute to chime in. Here's what I'm looking at...
Set up: Supercloset superbox w/ about 2 gallons in the reservoir
Plants: 1 single feminized auto, CBD Crack (28 days old and pre-flowering)
Light: 200w CFL on top and (2) 100w CFLs side lights. 20 hours on, 4 hours off.
Nutes: ~600ppm Technaflora (recipe for success)
Water: I start with distilled, add nutes, then pH to 5.6
Water temp: 64-72F (averages about 68F)
Air temp: 64-80F (averages about 76-78F with the lights on)
Humidity: 45-60% (averages about 50%)
Roots: Healthy and white. Starting to fill the res. 1/2 inch "hairs" everywhere.
pH: 5.6-6.1 swing every day, requiring pH down every day
I've done a ridiculous amount of research on everything, but as you know there aren't many "one size fits all" answers, and everyone has differing opinions. But here are some of the things I'm thinking about, if you know about or can comment on any of them ...
1. Can you have a healthy hydro plant if your pH swings from 5.6-6.1 and then back to 5.6 every day?
2. Is it even realistic to try to grow in a 2 gallon res? Do I need to use something at least 5-10 gallons in order to reduce the pH problems, and just waste a bunch of money on extra nutes?
This set up has 8 net pots and while you could never grow 8 plants in this box I've watched a bunch of YouTube videos where guys have grown multiple plants in the 2 gal res so hmmm
3. Is there something else I could be using besides GH pH down? I've read that another brand called Advanced Nutrients has a pH down that supposedly "lasts" a lot longer, requiring less to be added. Or should I be using vinegar or something else that won't cause a nute lockout and be better for my plant?
4. Am I making a huge noob mistake and totally missing something here??
Sorry for the long post. If you made it this far you're awesome!
