PinkParrot Creating the good growing conditions.
It's a closed room where AC turn 24/24h to maintain temperature at : [25-26Β°C - Day] [24Β°C - Night]
AC dry a lot, so i added a 8L humidifier at 100% power, target Humidity for this step is 85%
Fast start in the dark for the Lemon Orange seeds. But Persian Pie don't go out of the soil, I planted 2 more seeds by prevention, we will see soon..
I used a bad water (7,5 PH) because i haven't the tool to prepare it (now i have it). Possibly caused the slow germination of Indica seeds.
Edit : The 2 first PersianPie died in soil before showing there leaf, replaced by the previously prepared other ones.

PinkParrot Day 8-9 :
Good recovery after the 99% humidity episode, they look to feel better with nutrients
Day 10 : One malformed plant, i see two possible causes ; soil too wet or night light pollution from the humidifier .. π
(I open the Humidifier to unplug the useless LED + Install this one out of the tent, no more pollution.) π
Day 13-14 : Repotting the plants in 11L pot fill with only ~7L of substrate. (3L of lightmix soil - 3L of Coco Premium - <1L of Perlite). With this mix i hope moderate retention and faster roots development.
Power of the Lumatek 600W LED push from [25% = 150w] to [50% = 300w] πͺ
A good soul to look at my "Day 10 plant" please ?
I asked google but i seen nothing like that, the plant look to be okay, color good, but curled up..
Edit 1 : Max hygro of the night 99%, i will try to shut down the humidifier each night..
Poor ladies! Yeah, you've GOT to get that humidity down! And if you're giving that much water to them each day, they're drowning which is why they're drooping over. Between those two things, you're not allowing the plant to BREATHE!!!! It has nothing to do with the light coming from the humidifier at night!
Get your humidity down to about 50-60% and don't give them ANY water until the pot is super SUPER light (which means it's super SUPER dry)... You should see a great improvement quickly - well, at least when the soil starts to dry out!
Good luck!
PinkParrot Day 15 : A little incident with the AC, temp reach 31Β°C for ~12h. A little bit of C02 (Baking soda + Lemon juice) as been added to protect the plants.
Day 19 : The both lowest leaf want to talk with me, i think about a Mg deficiency (or Potassium / Nitrogen ?). I can water+fertilize tomorrow | note: Fake clue
Day 20 : [ Watering EC 1,1 | PH 5,8 ] => [ Run-off EC : 2,2 | PH 6,1 ] --- (Big EC out of the pot.. The Coco effect i suppose.)
If the problem persist, i will flush with a water [ EC 1,1 | PH 6 ]
Day 21 : Now sure the temp isn't the cause of the leaf disease. AC is (re)ON from the Day 18, Entry air temp 24Β°C -- Leaf temp 28Β°C
END OF WEEK/
- I think mix Coco & Soil 50/50 create assimilation problems at this moment because of PH & EC incompatibility.
- I suspect my "Grow" Fertilizer to, NPK : 7.5-5-14
- Blackout from 22:05 to 22;40.
Hi, one of my plants show sign of something but i'm not sure what it is.. Mg deficiency (or Potassium / Nitrogen ?)
I never used Platinium before.
Ref : Photo [Day 19 - A] & [Day 19 - B] --> It's the same plant, lowest leaf right and left.
Color difference is due to the camera
High Makaveli,
This I can ensure you for 100% is a nitrogen deficency.
The symptoms for a nitrogen deficiency in a cannabis plant
in the early stages are that the leaves appear to be too light in colour almost yellowish-green compared to the desired deep green of healthy leaves.
The cause of this deficiency could be underfeeding (but I am sure that this is not the case because your other plants look perfect and she is still to little to be that hungry for nitrogen).
Or overfeeding and I do think that this is your problem here a nutrient lockout due overfeeding. Or the pH of your soil is the cause for this nutrient lockout.
You can fix both of these problems with a good flush of your soil and I will explain you how you can do that the best.
You can do this flushing by slowly pour water onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot.
After the flushing you need to let the soil (almost) dry out completely.
From the moment that the soil is dry again you can start watering and build up your nutritions again. Start with a low dose EC 1.0 and if you do not have an EC meter around 25% of the amount that they recommend on the nutrition bottle. From here you can start up the nutes slowely again. But do not give more then EC 1.8 or 75% of the amount that they recommend on the nutrition bottle.
Happy Growing! π
PinkParrot Day 21 : Blackout from 22:05 to 22:40, they look to be ok after this event
I folded the side of the pots to leave them space
Day 22 : Leaf disease looked to stop their progression.. Targeting PH 6 for the next watering.
Note : If problem re appear i while flush with fertilizer to reach a better run-off EC
Day 23 : [ Super-cropping all plants ] Less stress than a topping, i prefer this method because i while use ScrOG after the next repotting to 20L pots
The growshop who offer me the fertilizer, [ GROW NPK : 7.5-5-14 ] ; when i show the NPK ratio , the seller's face immediately change haha
Professional, he give me a low grade Nitrogen fertilizer, i applied it on the leaf before the girls gonna sleep, because they don't need water in the soil for now.
Day 24 : Signs of overfertilization after the nitrogen application of yesterday.. I used 30% less than recommended, now I have serious doubt about Platinium Nutrients
Day 25 : Water [ PH 6 | EC 1 ] - Run-Off [ PH 6,1 | EC 1,7 ] => Look to be better, the runoff EC go down and PH stabilizing.
Day 29 : Water [ PH 6 | EC 0,9 ] - Run-Off [ PH 6,1 | EC 1,2 ] => One plant really need water

PinkParrot [+] Installation of a 3D printer in the room, now it's "easy" to make our own system revelant.
[+] Installation of a UPS.
[+] Installation of two rescue LED to counter the blackout effect, they are both 45W - 3600 Lumens. Turned ON daily with the same span than the Lumatek but these are powered by the UPS.
[+] Installation of a raspberry (powered by the UPS) - running #MyCodo software to manage and monitor the growroom.
Raspberry hardware :
-- IR emitter => Allowing usage of AC autonomously.
-- DHT22 Temp/Humidity sensor => Accurate measure instrument placed at level of the canopy.
-- Standard Raspi cam.
-- x8 5V-220V Relay => Allow managing external hardware like humidifier, extractor and more in the future.
[VPD target set to 0.9 kPa]
Day 46 : Run-Off for all : [EC 0,9 | PH 6,1] - Except Plant B => PH : 6,3
PinkParrot The free sample of Platinium nutrient look to be expired, crystallization of potassium.
It can be the source of K deficiency.
Dumping the "Grow" bottle, starting the bloom nutrients a little bit early to maintain the EC.
Unfortunately the "Bloom" bottle is crystallized to, now I use a mix of Platinium & Plagron to preserve the nutrition needed by the plants.
Why don't buy new bottles ? Because the next run will be full hydroponic, currently I'm just finishing the soil/coco nutrients.

PinkParrot After trying to reduce and up the PH, I think the leaf shows fake sign of (k) def
Now, thinking about a simple burn due to the lamp distance (from 20 to 30 cm)
[ Day 70: Add Lumatek 600w 2.9 to reach ~1050w total light ]
[ Day 72: Add/manage fans to offer the best airflow for our pretty girls. With this light, they need to breath a lot π ]
Finishing this week at 30cm from the canopy.
Next week, lamps go to >50cm
[ Lemon Orange 70% sativa ] Lot of brown leaves, starting from the tip
[ Persian pie 60% Indica ] less affected by the problem (same watering)
{ We tried }
PH 5,7 | & high PH 6,2
EC 0.9 | EC 1.2
Upper light
Cooler temp
Higher Fans speed
Note : Grow & Bloom bottles crystalized..
this grow will look very nice once you nip this nutrient burn in the bud! heh.
It's an easy fix too, believe it or not. All you have to do is water with just pH'ed water for a week, then diagnose the situation again. If it's still looking rough, keep watering with just pH'ed water.
When it looks good enough to reintroduce nutrients, try to give them very small doses and work them back up to decent feedings.
I hope this helps.
Good luck!
PinkParrot Harvest is approaching's, pushing the light to the limit 1200W end of flowering boost, 2 superposed Lumatek 600w !
This is the very last stress sprint for our babies
