0xmrcl // Day 8
The 500ml of yesterday did indeed give the plant some problems, so now watering for the next few days!
Doesnt look too bad i think shes gonna be just fine.
// Day 9
The leafes of CBD fix are bending a bit weird, seems to be caused by the ventilator that didnt listen to the controller and therefore ran on a high setting, too much directly pointed at the plants. At least thats my theory for now, lets see.
I have set the light 10cm higher. And set it a bit stronger for PPFD of 220.
// Day 10
Increased light to 270PPFD
Both plants are building their first 3 finger leaves :)
// Day 11
Both are still growing steadily.
Watered the Watermelon Candy 120ml as the first centimeters of soil were dust dry.
Wont water the CBD fix for some at least till day 13.
Discovered fungus gnats - Ordered Culinex.
// Day 12
Both plants are really picking up speed, significant growth can be seen.
The plants are beginning to produce axillary shoots at the nodes.
I'm planning to water the entire pot on day 13.
Everything is looking great!
// Day 13
Watered both plants with 1 liter each: 500 ml from the top and 500 ml from the bottom.
Added 2 ml/L Bio-Grow fertilizer.
CBD Fix is still letting its leaves hang down a bit, so let’s see if that corrects itself by tomorrow.
Both plants are still growing well.
// Day 14
The lower soil layer seems to have become mostly hydrophobic, so I gave each plant 5 liters of bottom watering.
Both plants are starting to develop their first axillary shoots, and the center of the canopy is filling in with plenty of new leaves.

0xmrcl New week, lets see how much they grow!
// Day 15
One day after the first big watering, it all seems to be looking good.
The CBD Fix’ leaves are the only thing with my plants that i am worried about, but i just need to be more patient.
Both plants are growing great, first 5 finger leaves are growing fast!
// Day 16
Moved light 10cm lower (now 50cm), resulting in a ppfd of 300.
// Day 17
Increased light power, resulting in a ppfd of around 350ppfd.
Increased RH from 62% to 64% to hit VPD target.
// Day 18
Added more Soil, pots are already a lot lighter than after watering.
Theyre both looking great, im really enjoying the Hobby!
// Day 19
Watered them again, each absorbed around 3.5 liters.
Spotted 2 hairs on CBD Fix that look like a flower indicator, really early flower, just to keep in mind.
Therefore added some Grow and Top-Max fertilizer for said plant.
// Day 20
Not much new, some new shoots are covered by big leaves, might do something about it soon, but not sure how for now.
Measured both plants, CBD Fix is already at a height of 23cm, Watermelon candy has 18cm but more dense leaves.
// Day 21
Figured the light might be too close now as the plants have grown a lot,
Moved the light 10cm higher (now 45cm from canopy). PPFD is now aroud 380.
Both plants are showing some white strings, signaling it will move to flower soon!
Lets see if she stretches!

Not much new, theyre growing great.
The white strings that indicate early Pre-Flower are developing steadily.
// Day 23
Increased Light to 500 ppfd on 40cm distance.Decrased Temp Dead-Zone from 2 degrees to one.
Soil is still really moist at the surface.
// Day 24
Tucked big leafes below the shoots so they get much more light.
Moved light higher to keep 35cm distance.
// Day 25
Watered them by Nutrition plan with Grow, Bloom, Top-Max, Alg-A-Mic
and Acti-Vera
Water. Candy absorbed 5 Liters of Water, CBD Fix absorbed 4.
Did not bottom water today, it was entirely given from the surface.
// Day 26
Since the CBD Fix stretches that much, about 5cm a day, i have to adjust the Light every Day, wont document that every time.
Both plants look perfectly healthy!
// Day 27
Increased light intensity from 60% to 65%.
This gave me an ppfd of 550-600.
// Day 28
Watered CBD Fix 5 Liters. Added 2.5ml of CalMag.
Light height adjusted, measured both plants, tucked some leafes down.
Decreased Humidity target to 57%.

Again almost 10 cm of growth overnight, i hope the stretch is over soon or ill have big height problems xD
// Day 30
Watered Water. Candy;
2ml/L Acti-Vera, 2ml/L Alga-Mic, Grow 2ml/L, Bloom 2ml/L, Top-Max 1ml/L,
Cal-Mag 0.5ml/L
CBD fix is still stretching, hopefully it doesnt reach the ceiling haha
Watermelon candy is now at the beginning of its stretch.
// Day 31
Relocated the dehumidifier so i can reach a lower humidity in the tent.
Dehumidifying the lung room and tent will be a challenge for the next weeks.
// Day 32
Watered the CBD Fix, added nutrients as planned in the schedule (Flower Week 2).
Did really light lillipopping.
// Day 33
Watered the Water. Candy 5 Liters, used nutient schedule flower week 3. 1ml/L CaldMag.
The Environment problems are the big struggle currently. Dehumidifier outside the tent, both tent and room have 55% RH , but that might cause budrot so if i put the dehumidifier inside the tent, i get 45% with 31 degrees at day, but 70% outside.
// Day 34
Watered CBD Fix 5 liters with 1ml/L CalMag.
Ordered something so i can guide the exhaust air out the window - this might fix my climate problems. Water. Candy is now also praying, they are both doing great!
Really satisfied for now!
