Lighting and Bud Health:
The new Sanlight lamp is proving to be effective, but the buds on #2 have started to bleach. I reduced the lamp’s power back to 80% and positioned it at an angle above the filter. The plants are now receiving between 25,000 and 30,000 lux, measured with my phone. The bleaching is not too visible in photos because the hairs on the calyxes are still white, but it was too much light for them. This should no longer be an issue, though the height of the plants is becoming a concern as they have reached their maximum height.
Space and Setup Adjustments:
I finally received my additional lamp, allowing me to move the Cereal Milk plant to a different room. Now, only two Cookies plants are under 160W. Both plants look very healthy. Cookie #1 did not stretch as much as #2 and the Cereal Milk, so I elevated it slightly to achieve a uniform canopy.
Environmental Conditions:
Temperatures in Germany have increased, and since I have an open living space with the plants in the living room, they are affected by the outdoor weather as I keep the windows open. Thankfully, the humidity is now between 50% and 60%, which is acceptable given the temperatures.
Relocation Plans:
To better control the environment, I am planning to move the setup to the basement. I have a 9 square meter room with a window where I can set up. This will allow me to use my climate control unit effectively. The plants are currently doing well under the existing plan, but the past iron deficiency and slightly burnt leaf tips from when the lamp was at 100% are still visible.
Future Setup:
In the basement, I will set up the lamp in an 80x80 cm tent for the Sanlight. For the two 60x60 cm tents, I will use the Mars Hydro FC 1500-EVO, which is perfect for one plant per tent. With five weeks of vegetative growth and considering the amount of leaf trimming and stretch during flowering, I believe each plant could easily fill its tent.
Overall Status:
The plants are thriving under the current conditions and adjustments. They look healthy, and the relocation to the basement should provide a more stable environment for continued growth and optimal flowering.
Midweek Update
Plant Status:
As the 4th week of bloom ends, the plants have stopped stretching, which is a relief. Thanks to the new lamp, I was able to remove the Cereal Milk plant, giving the two Cookies Gelato plants plenty of space. I gently pushed the stems outward, and the plants have responded positively.
Observations:
Unfortunately, upon closer inspection of the rear tip of #1, I noticed that it is deformed, as shown in the picture. We are already in the 4th week of bloom, and I can't utilize the space differently, so this plant will remain.
Purple Coloring:
I’m no longer concerned about the purple coloring. To maintain balance in the soil, I will aim to produce a 20% runoff when watering to flush out old nutrients.
Light Bleaching:
The bleaching on #2 seems to be only slightly affecting the tips and is not spreading to new growth. Therefore, I believe I do not need to reduce the light settings further.
Overall Health:
Despite these issues, the plants are generally healthy and have adapted well to the increased space. I am optimistic about their continued development.
End of Week:
I researched the phenotypes and found out there's a purple phenotype that grows smaller. That gives me peace of mind. I removed a few leaves from the mutated bud, and you could see water forming on them. The smell is currently lemony. The buds have continued to swell, and the resin production is joyfully increasing. They sparkle more each day when I open the tent.
Hey everyone, what do you think—do my plants have a phosphorus deficiency?
Two buds are turning a bit purple, and the lower leaves are easy to remove even though they are still green.
Photos are in my Grow diary.
Hello BussyBeeFarmer,
You got a nutrient lockout from nutrient salts builded up inside your soil. You give more then enough nutrients and everything the plant needs is there. But you need to water till 20% runoff to prevent nutrient salts building up and I would recommend to cut down your nutrients to 75% from whst you are giving now.
This should solve your problems and deficiencies buddy.
Happy Growing! 💚
Should I keep this deformed bud or cut it off? The humidity is high, and the sugar leaves are layered on top of each other. I'm a bit worried about potential mold. Any advice would be appreciated!
Thank you, @James! I'm glad to hear you think they look spectacular. Your encouragement means a lot! 👌 I'll definitely keep pushing forward and continue to give these plants the best care possible. Stay tuned for more updates!
It should be OK with the top max,top max is PK isn't it? It will more than likely be the light stress. I had it myself when I switched over to led,s because it wasn't warm enough.24 so increased to 28 and it stopped.I believe its mostly due to lack of radiant heat and the leaf surface temp.
@oldskoolkool, Hey, I've got some updates. It turns out that Top Max doesn't contain potassium or phosphorus its just a stimulant. Potassium comes from BioGrow, and phosphorus and nitrogen are in the bloom fertilizer. These nutrients are roughly in a 3:6 ratio compared to other substances in the mix. Because of this, I initially misinterpreted the deficiency symptoms, which led to the current situation.
It’s a bit confusing with BIOBIZZ if you don’t know that you can open the labels to get more information. Fortunately, I figured this out before things got worse. Thanks for the nudge to double-check the nutrients, saved my run!
@oldskoolkool, Thank you for your input! Yes, Top Max is PK. Since the plants are illuminated at night, they haven’t been below 22°C in the room for the past 2-3 weeks, even during "nighttime".
I just noticed a mutation on the plant and will update some pics later when I’m at home. Since the other two plants in the grow show no signs of phosphorus deficiency, I’m hoping it’s just a color change from some mother genetics. I haven’t found anything indicating that Cookies Gelato turns purple frequently.
I’m not too worried for now, though I’m not thrilled about seeing so many mutations in the RQS seeds. Maybe it’s something I’m doing? 😂😅
And thanks for the tip about the basement! I’ll make sure to keep them off the cold floor and maintain the temps.
Thanks! These are my first plants using these nutrients, and so far, I’m extremely satisfied. I used Hesi before this. Once I finish the grow, I’ll let you know if I can recommend them. So far, they’re looking really good!
Nice one. I ended up checking the top max for someone else and found out its Humic Acid which is especially good for organics as it makes the nutrients more available. I use it all the time in synthetic nutrients as its in my base grow,ph perfect sensi grow in the form of fulvic acid. I also use advanced nutrients Ancient earth in my organics as Iv been doing both sside by side for a few yrs now. If money isn't an issue then advanced nutrients are by far the best.They don't just add the 14 mineral eliments the plants need they add so much more. Their organic iguana juice has several times more ingredients than bio bizz,things that add flavour like fish hydroslate.Their whole organic range is amazing but its not cheap.
