Would anyone be able to provide input/advice on how my plants are doing?
Background:
System - 5-gallon DWC
Lights - Topshelf Duolux 600 LED
Temps - 75 to 80 degrees Fahrenheit
Humidity - 40-50%
No ventilation yet - only fans
No CO2 (closet grow)
No run-off
General Hydroponic nutrients (minimally at this point)
All plants at about week 3.
On the left is Bubba Kush Auto and on the right is Girl Scout Cookies Auto:
(The browning on the older leaves of the Bubba Kush auto and the spots on the GSC auto could be because the tube that was feeding the net pot had fallen out and I believe the plant wasn’t getting oxygen for a few days)
I try to keep pH at a round 6.0 (DWC, hydro) but my meter was not working for a few days (did not have calibration powder) so my pH may have been off for a few days.
Are you feeding or have you cause I know what this is. I see it all the time.
Yup my mistake should have read the hole question I just lookilookied at the pic’s and knew right away.
Stop feeding " Nutrients Burn "
Hydro
Change out the reservoir, flush out any lines and clean out the entire system and replace with plain water for the first hour, then start out with lower parts per million (PPM) Its good to clean out your system every 2 weeks and replace with fresh water and nutrients. Some people change everything every week!
Ahh, nute burn! Stop this by not adding to much chemical/organic nutrients to your water,foliar feeding. DONT feed more than 1 time a week unless using weak amount, use 1/4 strength for first feeding and then go up to 1/2 strength from then on when using chemical nutrients. Its very easy to overdo it. Causes leaf tips to appear yellow or burnt. NEVER give nutrients to plants that are under 2 weeks of age, at this age the soil nutrients are enough to suppliment them untill 2 weeks of age or more depending on how good your soil is. Using ferts before 2 weeks will almost likley kill your plants.
I have a
Of more info if you wpuild like I st ask and its yours.
Thanks Will, perhaps it was nutrient burn or pH issues. Unfortunately, I don’t have a system that allows me to flush very easily so I ended up adding pH water to dilute the nutrients.
I will keep vegetation lights for one more week and then flip to flowering lights.
Two mistakes I made for reference for first-time growers:
I kept the grow tent the door open in the first few weeks to control temperatures - not good. Loss of light = loss of growth. In the future, I will setup my fan to exhaust air before grow.
I placed two net pots in one 5 gallon bucket. As a result, the GSC has been fighting Bubba Kush for nutrients and therefore lacks growth.
I just signed up on the forum site and this is my first grow. Just received my auto flower seeds for white widow. It is 2nd day of Sept. in southwestern PA and although still pretty warm, fall is coming and nights are getting cooler. I want to get these going right away but not sure of best germination method. Is it best to soak in water first or can I put these directly in soil in there big pots and outside. Need help…thanks.
Hi Rexman, there are two methods you can choose from:
1.) Place seeds in a glass of water. When they sink and the taproot comes out, they are ready to be CAREFULLY placed in your medium (with the taproot down).
2.) The method I use is - fill glass with water, add about 1/2 teaspoon of liquid seaweed (any brand should do the job, I use Maxicorp Liquid Seaweed). Fold paper towel twice (to form a square), dip it in your liquid mixture. Squeeze out excess water, unfold one time and place seed in center. Place paper towel in a Ziploc bag and place in col towel in a Ziploc bag and place in a dark dry area.
Just open the paper towel and check if the taproot has been exposed.
