Hello guys, new member of your community here from EU, asking for your wisdom :)
Process: I've got tried 2x times auto feminized seeds (different strains), both times they died in veg stage sadly.
First one died because of overwatering (bad try to use cheap drip-from-a-bottle system with soil, it was constantly warm) and propably nutrient lockout problems).
Second one is dying right now.
Soil, nutrients: Some mix soil which was saved from first failed growth attempt - flashed out batmix allmix (ph 6.4-7.8), some new soil with ph 4.5-5.5 (with NPK 500/500/650), vermiculit, some urea non-liquid nutrient (NPK 46-0-0). Goal was to finally always see 6.1-6.2 ph water coming in runout (first attempt was always about 7~ runout, even if I fed 5.0 PH water to stabilize that).
Goal to save PH was reached, runout from water 6.1 ph was about 6.2 ph which I thought was ok.
Seed was germinated with small peat pallet, so I just installed that pallet with seedling into the soil (5litres ~ 1.3 gallon smart pot) and didnt add any nutrients for like 7-8 days, only clean water.
Then I started to see some yellowing and by reading symptoms suggested it needs a bit more nutrients.
Added some vega nutrient (NPK 3-1-4, 1ml per litre, fed about 1 litre totally).
This was one of the reasons I've got some problems in my case I guess.
Light: 100 watt LED with Sumsung LM301H diodes, 2.7 umol/j, about 2 feet above canopy, at 25% (seedling), to 50% (veg). Schedule is 18/6.
Using PPFD software on android and UT383BT sensor I'm seeing about 17k lux. With my LED from 450 to 750 nm with spikes on blue and red
WIth my light at 50% at 2 feet hight If I choose software options of pattern Red(650nm) + Blue(450nm), software shows for 18/6 schedule PPFD is 1536 umol/m2sec, and DLI is 99.5 mol/m2day which is very high.
But when I choose option of Red(650nm) + Blue(450nm) + White (3500K) I've got results 445 PPFD and 28.8 DLI which is "good". Not sure which one is correct so getting me messed up totally with that spectrum things.
Photos of spectrum from LED Manual:
Temp, Humidity: RH was around 75-80 on seedling stage, veg usually 55-65 range. Temp 22C (night) - 25-28C day.
Some timestamps and photos:
Day 7
Day 9
Day 11
Day 15
Day 23
At this moment I was scared, so I've decided to do some flushing and plant it into smaller pot to speed recovery (better control over nuts I guess).
While was flushing I saw that roots are no more than 2-3 inches inside ground, and there are very small amount of them, so 90% of big pot was empty all this time.
So, tried to fix problem this ways:
1. I've put some soil into smaller pot (1.7 litres, around 0.3 gallon, plastic one) and flushed it with 5L of water, added only powerzyme (1ml per litre) and PH 6.1 water.
2. I've put a plant a bit deeper , so distance between ground and leafes are a bit closer now, but plant seems more stable.
3. Cut old leaves
Now it's looking like that:
Now waiting for plagron coco A+B + power roots + biobizz Coco-mix to try over for better control of nutes and ph, if this one little girl still not gonna it.
It is really, really hard to tell what deficiency or exceed (toxicity) is going on based on my symptoms cause both times they did not come alone, always multiple of them.
Would appreciate any advices or comments, guys, and wish you a nice day!
p.s. Sorry for my english, I'm in a process of learning it :)
