First Grow: 4.5 x 5 With Mars 1600 LED

Hello!

Wish I had done some additional research before popping on the Mars 1600.. but it is what it is

I had a small bathroom in my bedroom which I converted into a 4.5 x 4.5 veg room with 2 t8s and a 4.5 x 5 flower room. Started in 1 gallon pots using happy frog soil with %50 perlite.

Planted 5 feminized og kush and 3 regular red purps.

Moved them after only 4 days under the t8s due to the need for more warmth. Still having days at 0 degrees but averaging around 30 so lights are on 24/7 and temps remain constant around 72 with Rh of 40-60

I had one OG die shortly after moving it under the LED. Initially I think the light might have been too close at 24 inches and pulled it up to 30. This may or may not have caused some of the first leaves to curl on some. A feminized Humboldt ewe 2 and another OG were starter a week or so after the first seedlings.

The larger plants are now sitting on day 20 from being planted in soil. They were feed 6.5ph RO water the first 10 days. I added 1-2ml of molasses per gallon every feed since then. Gave them a small feeding of Fox farm big bloom 3 days ago 1.5ml per gallon. Cal-mag should be arriving tomorrow which will be given on their next feed with no other nutes. Should have been doing cal-mag from the start but it wasn't in the budget.

I hope to keep this updated and I will not post anymore purple pictures from this point on!

Came home today and one plant was dropping severely. They still haven't had water for 4 days so it's not overwatering.. I'm guessing too much light. I raised the light yesterday to 30 inches but then turned it to full spectrum after reading somewhere that people do that..

Hope she recovers soon and the rest don't fall over

Not looking better today. Cal-mag finally came a day late and the girls got 5ml in a gallon of 6.7 ro water. They all look droppy and sad. Shouldn't be light stress.. light is 30 inches above top growth and only on the veg switch. I did have a fan blowing on them with constant movement to the group. Turned the fan against the wall, hoping maybe they just need a gentlier breeze.

Tested the run off ph of all plants and they were 6.3-6.5. Ppm run off was 1 - 1.5 ppt which I'm thinking is high. Will do another water when they are dry again in a few days with no nutes except cal-mag.

You will benefit from reflective walls, I've seen a difference in my plants using leds with an enclosed space with reflective material vs. not. Dunno if your making plans for it but later on in the plants growth is when you will see it having the most impact. Happy growin!

Yes I know... kinda rushed into the grow before the room was completely finished. Had expected to veg in another part of the room with painted flat white walls but due to temps needed to bring them into the room with the warmer light.

What are people's thoughts on if I painted the room while the plants were out of the room when I switch to a dark cycle, throw the fan on high for about 4-5 hours while paint dries and then put the plants back into the room. Do you think the fresh paint would have any negetive effect on them?

Translated into 7 gallon smart pots yesterday. Kept the 5 og kush in the larger room and moved the 3 red purps and ewe 2 under the t8s. One of the red purps was drooping a lot before the transplant and has started to perk back up today! Had to buy 16 gallons of water at the grocery store for feeding. Have some extra jugs to fill up with ro water now on off water days. Going to do another no nutes feeding the next time they are in need and then top the girls that are ready.

Noticed these on red purps #1 today.. is this a male? Surprised it's showing sex after 30 days out of soil under 24/7 lights
 
Killed the suspect plant..

2 purps and 1 humbolt ewe 2 under the t8s looking very healthy today.

5 ogs doing ok.. feels like they are growing slow. Turned off the bloom switch on the light and will just run the veg spectrum to see if things improve.

Moved the smaller OG under the t8s and everything seems to be going pretty good in both areas. Noticed some retarded new growth on one plant that had also had a part of a leaf what looks like was chewed but no visible pests... maybe someone else might have an idea what's causing this?

Decided to put all but 1 red purps under the LED. Put insulated foam blocks under the grow bags to keep them off the cold floor. They sure are starting to look pretty.
