Home Grown Tomato, Vegetable & Herb Fertilizer 4-6-3
3.91 mll
ober37 03/17/2024 - Using 3 germination methods for this grow with 2 seeds each:
- Paper Towel
- Cotton Pad
- Directly in Substate
03/21/2024 - Watered with 40ml + great white
03/24/2024 - Watered with 40ml + great white.
Lights at 280 PPFD / 10"
Pheno #1 / #2 - Directly in dirt
Pheno #3 / #4 - Paper Towel
Pheno #5 / #6 - Cotton Pad Method
Changes that Worked
- The paper towel adjustments from growcast using spring water worked perfectly
- having a ph of water post germination of 6.5 worked for me
- Start with using mosquito bits in water so that you address problems super early
Lessons Learned
- Track the pheno # against the germination method, outside of #1 and #2, I lost track
- The "packing down" from Build a Soil did not seem to serve me well, stop doing that
- Track the day each pheno germinated with photo updates
- These were quite stretchy, moved the light to 12", kept PPFD in the high 200s (270-300) and lowered temperature to 75F

Tranplanted into 1g pots that I ultimately will take into flower. Leveraging a DLI from 30-38 depending on where you measure.
Phenos 2, 4, 5 made the cut.

MB from Growcast suggested that I might have a zinc deficiency.
After looking into it a bit more and chatting with the folks at Royal Gold, I should be using 6.0 as my ideal pH and not 6.3-6.5.
The theory is that the pH is too high and the zinc is not being properly received.
Fed this morning with 5.9 pH water and 330ML of water + fungi.
I'll have some Foop mist and Zinc spray coming later today, hopefully this gives them all a boost.

Last week discovered I had a zinc deficiency due to a ph lock out, where I should have been using 6.0 in this coco-based soil (confirmed with Royal Gold).
About 3 days since I updated this, used a foliar spray and will be adding this weekly this week.

Updated DLI to be around 45-50.
The plants have been struggling and I think it's due to bad pH, I recalibrated by pen to realize that it was a bit off.
Fully saturated media with new pH water and we'll go from there.
I used the budklips and ended up breaking some branches, so I'll stop using these in the future.

Struggling with zinc deficiencies and in general I think the plants are really hungry.
I am starting to think that using rice hulls with coco was a bad choice
05/01/24
Used a seaweed foliar spray and added some in my waterings now, which has been helpful.
Watering 300-330ml per day day per plant, which is serving me well.
M - Seaweed (50%)
T - Seaweed (50%)
W - Mammoth / Seaweed
Th - Seaweed (50%)
F - Seaweed (50%)
Sat - Recharge
Sun - Mammoth / Seaweed / SLF-100

Plants have been looking better up until today and seems like zinc continues to be an issue.
Going to add more nutes or foliar spray shortly.

Did not need to feed just yet, the seaweed water is helping with the micronutes.

Plants are looking good and bulking up.
Have a light fungus gnat issue that I'll need to figure out a plan around.
ober37 06/09
Watered with 1L each plant today with SLF-100 to knock out some of the salt buildup.
Will skip watering on Monday.

at least 1 of the phenos will be ready next week and the other 2 will be ready in 2. weeks.

Started to dryback, so watering 500ml every other day to force them to ripen
