Sick Seedlings

Give them three days to adjust and recover. After three days, they should take off like nothing happened.

Oil Heater on a controller. 1500 watt can warm quite a bit of space. Like it all, there's math.

Wattage needed per cubic feet. With mine, I need 750 watts. The oil heater has three settings. 1500watt, 900, and 600. I use the 900watt with a plug in room temp controller.

Don't restrict air flow. You need all you can get.
My ambient house temp is 19c. On the other side of my grow room wall is a biomass heater, stopping the room temp from dropping below 19c. so i doubt ill need to add extra heating. Also have anohter ts600 and 2 660nm 50w flower lights for later.

Hopefully should see some changes. Thanks Beehive.

Its difficult at first but after you get the hang of it. You'll really enjoy a good led light. It took me a couple years of tuning mine. Distance between light pods, position. How many. What heat sinks. What voltage can I use.

Its a tinkering. But once its right. Wholly shit. I don't have to worry if its not enough or too much. Brother, I got it covered. You'll see. Welcome to the led world.

Its been anything but boring.

I get you buddy, I seem to pick up HPS growing pretty quick, grew some massive buds, but it didn't take me long to realize LED is where i needed to be for the crem del a crem's. with out needing a personal power station...

I cant wait until i'm producing Peng.

Good Time's

The MH and HPS are in my past. They're never coming back. Like an ex girlfriend type deal. It was fun while it lasted. Excellent smoke....kinda. Not really. Not since Led.

I can definitely see an improvement in the leafs of the stronger 3 with the centers starting grow out. Growth has picked up for sure.

From here ill continue to water with 0.5ml per ltr CalMag. Can you give us an idea when they tend to require more or less CalMag through out the growing cycle.

Air temp is stable at 28c and soil temp no longer feels cold to the touch.

I did have a black fly problem with my last grow, but have recently treated all plants in my house with nematodes, just seeing the odd one now.

funny how you can treat a group of seedlings the same way and one of them gets gimpy. Your plants look good, I'm sure the runt will grow out of this issue, its all about growing good roots!

They responded nicely! Perky, bold, and strong. Look at them go. In a day or two they'll really start screaming along. Node after node.

I think we have some happy Girl's. Just fed the strongest 3 with 0.25ml Grow, 0.25ml Fishmix, 0.5ml CalMag Per LTR. The other 2 just CalMag till they recover some more.

:D

Remember, they'll need cal mag for the rest of their life. You can't stop or you'll get a mag problem. There's something about LEDs that specifically causes it. Every plant I've ran until a couple years ago would show the rust spots. Particularly in soil. When I moved to coco, I'd get one plant out 4 that would rust. The others were fine. Same dose between them all. But that one plant needed a bigger dose.

Cal-Mag calls for 3-5ml per gallon. Cal Magic calls for 2.5ml.

I run 2.5 Cal Magic per gallon. 6ml for 10 quarts. I'm not a fertilizer scientist but I like Cal Magic more then Cal-Mag. First its stronger by the dose. Second, it stays mixed up better then Cal-Mag. You don't have to shake it as much. Also a better smell. Not baby diaper ointment of Cal-Mag.

Hey just wanted to thankyou for you're advise. its made all the difference, i was on another forum for over a year with the same problems but never figured out what the problem was. calmag has made all the difference.

they look better but not great in my opinion sorry something is still off

I think their calling for nitrogen atm and im trying not to over water, so i might be causing a tiny bit of stress with my lack of confidence.

oh and the photo was taken 5 mins after lights on and after a water and feed, so they might not look as strong as they really are.

The 2 smaller ones are still recovering from calmag deficiency.

I have some bleaching on the tips of one plant, not sure if its light stress from being in the corner and getting alot of reflection of the walls. Also the light was about 19/20 inches above the plants, now moved up to 24 inches again.

Temp is 28c stable and RH is 63%.

Im watering around 2 Ltrs each with no run off every 24hours and there drinking there pots bone dry. I would like to give them more, but im not sure if the roots can take it right now and I really dont want to lose any veg time to stress or overwatering.

21 days old today from germination.
