She is amazing! Week 7!
For now she's receiving around 2 watering's per week. One with the nutrients, the other one without anything (aside from pH-Down). And I think this is a great schedule for her, bc she's not getting nutrient-burn or nutrient-deficiencies.
Update Week 7:
She kicked into the main-bud development phase. Also, her leaves are slowly but surely turning purple. I think it's due to the production of anthocyanin, a pigment which in it's natural state is in fact purple. She's being kept at around 20-21°C at night, which leads me to believe, that the purple color isn't the chlorophyll breaking down.
She's doing great an the buds became significantly larger over the span of a week.
I measured around 6,9 pH on output water after her last watering. Not great, not bad. I reduced the input water to around 6,2 pH. Maybe that'll fix this.
@NiceCrits, hydroponics take more nutrients in my opinion so it will cost more but I know it for sure produces higher quality plants and everything grows quicker I just like soil because of terpene production
@Treesus01, I also like their products. However, Fish Mix smells and growing with CO2 in a tent requires adding additional P and a lot more K.
I think for my next grow I will go Coco Coir or Hydroponic (which is expensive to do right).
@Treesus01, Yeah, it's pretty easy to use and they provide a nutrient plan for their soil. Just have to regulate the pH after adding nutrients to your water.
Hallo from Berlin!
I have grown a few Medusa F1's, including in CO2 and high PPFD. I am using BioBizz as well.
A little bit of light burn on the tips is okay...
Your Medusa F1 is yellow at the tips, including the lower nodes. Usually with light burn, it's just the top nodes and they get crispy/brown. This looks like it could be nutrients.
Check your soil runoff PH and EC. If you don't have a meter, you can find cheap combo meters on Amazon.
If those are in normal range, it's probably a hunger for Potassium. If it is a nutrient problem, don't overreact :-) Fixable.
@Herikus, I look forward to seeing the progress. It's a good idea to check the PH of the water. Mine is around 7.0 and when I add the Biobizz nutes it raises it to 7.2
Previously, I used citric acid to lower the PH to 6.2-6.3. However, if you're using a reservoir, it doesn't keep the PH lowered very long. Thus I switched to Phosphoric Acid. It's a longer-lasting buffer and also adds nutrients.
Good luck!
@NiceCrits, great to hear from you! I think it was a combo of nutrient burn and light burn. Didn't check the pH of my runoff-water just yet, but I will definitely do that!
I probably need to lower the pH of my input water (the soil was quite acidic when I checked in Week 2) and chill out with the nutrients for another 1-2 watering's.
I'm pretty new to growing, so I'm learning on the go. And yes, I'm not planning on overreacting. If I'm remembering correctly from my biology degree, almost everything is fixable on a plant!
So thank you for all the helpful information!
