This is my first run doing a 4 site non recirculating dwc. As soon as they sprout up I mist them with a low concentration of rhizotonic.
I will be using the full canna aqua line including all the additives, plus some cal mag.
All water used is reverse osmosis ph to 5.8
18/6 light cycle for veg 12/12 for flower.
I am running 2 autos and 2 photos this grow.
Day 3: all of them seem to be stretching too quickly. I adjusted the lights closer to combat this. Spraying a couple times a day with a 1L spray bottle with 2ml of Rhizotonic. They are being grown in a humidity dome. The temps have been around 72F-75F during the day and sometimes dipping to 63F during the night. We are currently experiencing severe cold weather in the area and my heat pump is struggling to heat the house. The humidity in the tent today was low, around 38%. I have a proper dehumidifier however, I haven't had to battle low humidity in the year Ive been growing like this. I have a small humidifier that can hopefully keep up.
I started with a new bucket change to usher in the start of veg. I dumped and rinsed the old nutes out of the buckets and sprayed them with hydrogen peroxide.
In each bucket:
ro water
25ml Aqua Vega A
25ml Aqa Vega B
25ml Rhizotonic
25 ml Cannazyme
~5.8 ph
This week I started with a lot of browning of the roots that cleared up after a couple of days with the cannazyme and hydroguard added this week. I noticed a cal/mag deficiency so they are getting a dose of it this week. I topped citradelic sunset and have been using LST on all.
The roots have cleared up nicely over the past week and are looking healthy.
Purple Pope - This thing is bushing out ridiculiously. I plan on doing a defoliation right before flower. This plant has barely even a blemish on it.
Citradelic Sunset -
Anyone have an idea to what is wrong with this CBD plant on this week?
3 Weeks old
Temp 79
RH 45%
pH 5.8
18/6 light cycle
5 gallon dwc
EC 1.2
Full Canna Aqua nute line + cal mag
The new growth has been very slow and is drooping.
The 3 other plants in the tent are fine.
I'm not a hydro grower but from what I'm told you need to look at the roots and see if anything is off.
Is there good aerating for dissolving oxygen, do they smell at all?
are you using a enzyme product to help keep them clean and healthy?
This looks a bit like a PH issues/calcium to me. are their large PH fluctuations happening?
5.8-5.9 in veg is good and then bump it up to 6.2-6.3 in flower.
First step I would take is to calibrate your PH pen and go from there.
Then smell and feel the roots that's a good indicator of health.
Again I'm not a hydro grower, just guessing from what I have seen/heard.
Good Luck!
I flipped the light cycle to 12/12 this week.
They are close to filling my tent at the moment.
There is a lingering problem with the CBD plant that I can't figure out.
