So 1 have 4 plants going right now. They are under a 1000w HPS dimmed to 750w, about 2 feet away. They are in 5 gal buckets with hardware store soil that had perlite mixed in. They have an new york city autoflower strain. They are in a 4x8 tent with air cooled lights and exhaust fan through carbon filter. They have gotten some plain fresh water small sprays and feeding until a few days ago, they got their first feeding of a small weaked dose of Sensi grow A/B and a dash of Iguana juice grow, pH about 6.5, dechlorinated tap water, with pH down. Temp is about 77F and RH is about 35% at the planter and 76F and 50% at the top of the tent. They about 10/11 days old from when they sprouted out of the soil after being germinated. I only have a big box fan in there blowing on them, which I turned down and away from there as I read that could be part of the problem. (I think any spots on the plants are from where I splashed nuts pouring too fast)
As you can see from the photo's
#1 looks fine I think and going good.
#2 and #3 are both curling their top leaves up. The soil is moist, water drained out last night when I gave them about 3-4 liters each.
#4 just looks weird and different than the rest. It's a very dark green and the leaves look weirdly shaped.
For #2 and #3, I've read that it could be heat stress but the air cooling keeps the lights very cool, no heat from my hand underneath and I've been raising them a bit day by day in case it was that with little effect. I also read it could be the fan blowing too much on them, so I moved it to blow against the walls of the tent and getting deflected air flow instead of direct as I could be drying out the leaves too much with the fan directly on them. I only did that today so I don't know if that will help. I read it could be the roots and soil too compact, but I got good drainage from watering. I know next time I will mix in extra perlite or get better soil and I'm hesitant to just dig them up to see how the roots are or anything yet. It could be humidity I've read too, so I'm going to try a bowl of water in front of the fan for now to help a bit maybe and look at a humidifier.
Whats up with #4? lol. Just different phenotype in the strain and not stablized or was it stunted? It did pop out with "helmet head" that I had to remove with tweezers.
Anyways, thanks for the help. Anymore info, let me know what you need to know. I have 3 more that just popped from the soil and 3 more germinating so far on the otherside of the tent with the lights higher and only on 600w that are doing ok so far.
