Rockwool with 50/50 Coco Perlite and Autopot

[smokeyfromau]

I got a tag from Blue,, not sure i am much help as i am a soil grower, though for seeds i soak in water over night, then direct into the medium, previous method was paper towel

Thanks all.. so far everything looks good.. a little slow start but seems like they are slowly growing with about 1 liter of water every other day.

Here is my set up: - 2 HLG QB lights (135 and 100v2) hanging around 20 inches from the plant. My concern is the plant in the middle will not get as big. I do have another light (cheap 600W LED grow light from Amazon) that I was thinking of putting in the middle to get extra light - thoughts? or overkill

My first plant - Think Different - Growth was a little stunted with too much water in the rockwool but has been growing steadily now.

Dutch Passion - Think Different - Middle - I expect this to be a little smaller (~1 week from germination)

Amnesia Haze 1 - This is under my HLG 100 - 3000K light (~1 week - same time as the middle)

Your middle plant should be getting PLENTY of light. Its getting the offshoot lighting from BOTH lights. That middle plant will likely be the best one because its essentially being lit evenly at angles in lieu of the "hot spot" directly beneath the fixture. It should cause it to grow out more bushy and less tall straight up.

nice.. checked today and everything is slowly growing... im at a consistant 79 degrees/ 65% humidity...

When do you all think I should turn on the aqua valve and start feeding nutes?

CHecked today and have not seen much growth since the above pictures. I am concerned these have been stunted as the first one is going on 10 days and still has not gotten bigger than two leaves. The second two are about 7 days old and seem to be a smaller than I hoped.

I have been watering every 3 days, with light nutes (megacrop), great white, and hydroguard mixed with tap water for a PH of 5.8. I would usually pour around ~700ML to 1L for each plant (4 gallon autopot) or to run off.

I noticed my first pot (Think Different 10 day old) would have water on the bottom of the autopot. I had cleaned the tray and repoured this light nute water yesterday, and today, I see a big puddle of water. Much more than other plants who are in the same medium, pot, water.
I tested the run off water PH (7.1) and EC (1.1), which I think makes sense.


1.) Did I stunt this first plant? I had trouble with it in the rockwool when I had over watered and it took some time to pop as a result.
2.) Am I overwatering if I am seeing run off water? I know Coco has no nutrients and these dont need much but 1L every three days does not seem like much. Am I underwatering? I know @MANNIK had this underwatering issue.
3.) At this point, can I recover the first Think Different, if this is 10 days and has not grown bigger?

Thanks all

My suggestion is to take your pots out of the trays until they're hooked up.

Run a gallon or two of 6.0 ph nutes through the pots and let them drain. This will help to reset your root zone. Water around the rockwool to avoid soaking it.

Then put them back in the tent elevated out of the autopots so they don't stay in the runoff.

You will need about 2 liters give or take to water 4 gallons of Coco.

Aqua valves go on when the leaves get to the edges of the pots.

Dutch Passion genetics are strong and the timeline to finish is a bit longer than normal. They should be fine if you get it corrected now.

I thought airstones in the autopot res, at least with MC, were not a good idea, while a waterpump could help? Something about one affecting pH while the other helps MC not sediment.

And @jokgga Id say your lights are too close? 20 inches i understood right? Maybe icnrease to 28 orr 30 for a while? And maybe runoff EC of 1.1 for seedlings is a bit too high, whats going in? Don't bother with pH runoff. If you want to know your medium pH, it would be much better with a slurry.
