Hello all!
this is my first grow in almost 20 years but it just became legal in my state(Arizona) so here we go.
I have been having some trouble getting my plants going. I am adding lots of details to try to figure this out so bear with me. Before I get into that, here is my setup:
-using Vision Seeds White Widow and Sweet Seeds Sweet Skunk F1. Both femisized.
-I bought the Spider farmer 2x2(53” tall) tent setup with a fan and sf1000d light from Amazon.
-I repurposed a humidity controller from cheesemaking and have it plugged into a humidifier. This keeps the humidity between 50-60%.
-i
-I put together a dwc rig with a big air pump and 3” net pots. I fill it with 7 gallons which puts it about 1/2” below the bottom of the net pots. I am growing 2 plants in this.
- General Hydroponics Flora series nutrients
-PH and TDS pens in addition to a ph drop kit
To start, I soaked some rockwool in ph adjusted(6) water and then tucked a seed in each cube. I put these in a Tupperware covered in plastic wrap to make a humidity dome. I put these in the tent under the light. They sprouted and had a small root sticking out after 4 days.
I filled up the reservoir with tap water and the first week of nutrients ph adjusted to 6 following this schedule:
I had initially kept the tent inside the house as it was too cold to start in the I heated garage where it would eventually live. After a few days, the weather warmed up so I moved it to the garage. The light adds enough heat to keep the air temp in the 55-80F range even though it gets colder than that in the garage. I have not measured reservoir temp.
I saw some yellowing on the seedlings so I started looking into problems. First off, I had a 3” hole I was using to add nutrients So the reservoir had a massive light leak. This may have led to the ph rising up to almost 7.5. The water is also very hard here so the ppm with these nutrients was 600. After a week I was seeing very little growth so I changed the reservoir and cut the tap water with 3 gallons of distilled water. I thought maybe I needed more nutrients so I upped it to the next level using the sheet above.
This did not help. The next week I switched to a mixture of distilled and spring water. I went back to the week 1 level of nutrients and the ph has stayed right around 6 and the ppm is 390. The plants are still barely growing and look pretty yellow. The big one is about 2” tall and the smaller one is an inch. I am about 4 weeks from germination.
I am going to switch to 100% distilled with cal mag and hydroguard today. I am thinking of going to 1/2 of the amounts listed for nutrients for week 1.
Any ideas? Too much light? Reservoir water too cold? I am grasping at straws and feeling frustrated. I have some more seeds and rapid rooters if it makes more sense to just start over. Any thoughts or ideas would be greatly appreciated! Thanks in advance!
