420DeepGrow Thanks to the team at Royal Queen Seeds, Xpert Nutrients, and Mars Hydro — without them, this wouldn't be possible.
🖊️⛽ Permanent Marker:
Feminized photoperiod genetic from Royal Queen Seeds. A variety that stands out for its structure, resin production, and an intense and very characteristic aromatic profile.
A plant with good vigor, balanced structure, and a flowering that promises a large amount of resin. Its profile combines sweet and fruity notes with an intense fuel background and that characteristic aroma reminiscent of a permanent marker.
📆 Week 0:
Starting indoors. Germination with stable initial development, aiming from the beginning to promote a strong root system and clean growth.
The first days focused on establishing a good base for the cycle. Gentle watering with Master Root, keeping the substrate aerated and slightly moist.
⚡ EC: 0.3
💧 pH: 6.2
🌡️ Water: 21°C
🌫️ Humidity: 70–80%
💡 Intensity: 200–250 PPFD
🔥 Grow note: A genetic that I was really eager to try due to its fame and that particular aromatic profile. It will be interesting to see how it evolves and what expression it shows throughout the grow.
We're continuing to grow strong 💪!

420DeepGrow 📆 Week 1:
During this first week, the plant continues to establish its roots and starts to gain strength little by little. It has been a somewhat complicated week due to the high temperatures, which have made it difficult to maintain humidity within the desired parameters.
I’m introducing Master Grow in low doses to support vegetative development progressively, while also keeping Master Root to encourage root development.

The Caramel Pineapple is starting to change in appearance. The little buds are already forming at the tips, and each day it's clearer where the flowering will concentrate. The stretch is still ongoing, but the plant is beginning to focus more on those first flowers.
I'm continuing with Sugar Shot, Silica Force, Enzymes, and Sticky Finger at medium doses, maintaining an EC of 1.1.

The flowering is gaining presence and the little buds are starting to develop, with the pistils becoming more visible and the first signs of resin on the flowers. The stretch is gradually losing strength and the plant is beginning to concentrate more on floral formation.
I raise the EC to 1.2 and keep Sugar Shot, Silica Force, Enzymes, and Sticky Finger at medium doses. With the arrival of the rains, I turn on the gas heater to help maintain a more stable temperature and activate the UVB for 1 hour in the middle of the cycle.

The buds are starting to gain density and the resin is becoming more prominent on the flowers. The floral evolution continues, although this week I notice a slightly more aggressive Fade in the leaves, so I adjust the lighting to moderate the stress and maintain balanced growth.
I raise the EC to 1.4, reduce the light intensity to 80%, and shorten the UVB exposure to 30 minutes halfway through the cycle. I keep Sugar Shot, Silica Force, Enzymes, and Sticky Finger at medium doses, closely monitoring the plant's response.
