cup germination using plain water with hydrogen peroxide to kill of possible harmful bacteria's and for a speedy germination.
Will use Biobizz products mix for the whole grow.
Soil = Biobizz Light mix
pré-treated soil with organic liquid soil fungicide to kill of pathogens like verticillium, pythium and fusarium.
One of the seedlings hatched entirely in the wet paper.
Transplanted in soil; monday 2/3 october midnight
10ml water divided in two... first watered the hole and after transplanting watered the rest (with a syringe).
Heighth of light; 60cm
Intensity 25%
Lux: between 4000-5000
5 october: watered around the dome; 15-20ml with biobizz root juice (0,5ml/l)
7 october: sprayed the center part near the stem to keep the first mini roots moist ( root juice + acti vera 1ml/l)
Day 8) one of the seedlings fell over (grow question). Luckily no damping off.
Same amount and procedure as the other plants but still got underwatered... Weird but life must go on. :-)
Day 9) watered 125ml per plant.
Plant 2, the weak seedling, got back up in no time.
One of it's cotyledons shrinked a bit at the tip. I believe it absorbed some moisture from the cotyledon.
Day 11) plant 2 has slow growth due to stress of underwatering before. One of the cotyledons look somewhat dry/crispy. I cut the dry part off.
Plant 1 height: 8cm (doing ok)
plant 2 height: 6cm/2,3inch
Day 12) watered 200ml per plant
plant 2 is behind schedule. Leaves are growing but needed to catch up and it took 3 days to have some movement.
kept intensity around 5000-7000 lux = +- 130-180 ppfd for these seedlings
It was laying flat when i woke up. I have been using domes untill yesterday and I thought it was because of the fan first. I put some soil around the stem but didn't help. Toothpicks are holding it now.
Looked deeper and I didn't see a thinner stem nor a dent.
If your seedling is drooping hard, the issue is usually either over or under watering or that the seedling has stretched too much and cannot hold itself up anymore. You can add a little more soil around it to support it better, and if it seems to want to stretch more than it should, it's a sign to add more light.
However given this also happened right after taking dome off, consider if the air humidity change was too big and you should get the RH up in the tent, or if you just haven't factored in how much faster it loses water when it's not covered. You can also just try to put the dome on and see if that makes it go back to normal, that's a sign that it's environmental stress and you might want to just consider keeping it on a little longer especially if you can't up the tent RH.
Day 15 / 17oct)
watered 270ml with plant 1
200ml with plant 2 since it is smaller and behind on schedule.
Lowered the LED to 40cm
Intensity increased to +- 40% (17000 lux plant 1 and almost 16000 plant 2)
Day 19)
Plant 1 watered 400ml added fish mix 1ml/l
Plany 2 watered 250ml added fish mix 0,5ml/l. There is growth but still small
Increased intensity to around 20-21.000 lux / 500-540 ppfd
Day 21)
Watered 500ml - plant 1
Watered 375ml - plant 2 smaller
Day 23) foliar spray before dark
bio heaven 1ml/l + calmag 0.125 ml/l
Day 24)
Watered 625ml per plant 1 in 3x
plant 2; 500ml
Day 25 + 26) foliar spray
Day 27)
500ml plant 1
Added alga mic
Increased intensity to 24000 lux
Day 29)
Both plants 1L
Second plant got some calmag
last time with fish mix
Day 31)
little bit of LST for plant 1
Day 33)
plant 1; 1,25L - replaced fish mix with grow
plant 2; 1L plain water ph 6.2, no feeding
Day 34) Foliar spray Heaven + Alga Mic
Day 35)
Defoliation
Plant 1: 28 cm
Plant 2: 18 cm
This week lots of energy went into branching
Day 36)
Plant 1 - 1L
Plant 2 - 750 ml
Day 37)
First plant is doing great but after the increase of intensity, tips of the leaves have become yellow. It receives 35.000 lux
The second (smaller) plant gets also around 35.000 lux. I put it's tray on a plastic pot to highten it up towards the led so it gets enough light.
Day 39)
Plant 1 - 1,2 L
Plant 2 - 700 ml (risky with overwatering)
Plant 2 switched sides and is under the second Led with less developed plants.
Both plants receive around 40.000 lux
Smaller plant has claws which could be nutrient burn (N). Bigger plant has brownish/purplish pistils possibly light burn. Adjusted distance tot 40cm.
Day 43
plant 1: 1,4 liter
plant 2: 1 liter of plain water with only stress supplement (alga mic) and cut the grow feed.
Day 47
Fully plain Ph'd water, both plants 1L
Day 49
Plain ph'd water -
Plant 1- 500 ml
Plant 1 has a nutrient lockout.
Plant 2 nutrient burn (clawing)
Day 51
1L plain ph'd water per plant.
No more feeding. Next watering will be 2,5L to flush some excess out.
Day 53
2,5L per plant. No feed.
Day 54
Plant 1 shows regeneration. It grew more white pistils at the top.
Plant 2 has gotten slightly fatter buds.
Day 56
Plant 1 has lots of budsites and is preparing for fatter buds. Pistils have improved.
Plant 2 still has curly tips due to overfeeding and it's doing it's thing.
Plant 1 is getting thicker buds. I like how it has lots of bud sites. Shame that it had to deal with a nutrient lock out before otherwise the buds would have been massive...
Plant 2 less bud sites but they are thicker than plant 1
Day 64
Both plants got 2,5L watering.
I would give them a week or 1,5 max
Day 67
Plant 1;
2,5L
Day 68
Plant 1; 2,5L
