In the res. Ive done it a few times before on plants in flower, but never had to this early. Usually just a quick fix until nutrients in the soil were made available. When they're hungry, it's amazing how fast they drink up that salt water. Aqua Flakes says 5ml/gallon for soil, but I'm thinking that's for top watering into something like promix or a potting soil without a lot of nutrients. So I went with the dwc amount. I'll follow the 3ml/G recommendation for the next few weeks, then bump it down to 1.5 ml/G. I guess the plant can pick where it wants to pull nutrients, from the soil or from the res?
Cool,was always under the impression that its not good to do that.I guess as long as its not too strong and it doesn't go dry the plant wicks it all up.

Edit; maybe its organic stuff that I was thinking?

You're probably right :lol: I forgot to mention I do add Multi Zen to the res with the A & B. When I ran my dwc run, I used it in the res, and never had any root issues, im assuming it helped :eyesmoke:
I thought about the soil getting too saturated with salts, but she's so hungry, im guessing she's gonna eat whatever I throw at her, as long as I don't go crazy.

There's organic feed you can add to the res. Build a bloom has an npk of 2-10-5, growers secret nitrogen has an npk of 14-0-0. Both are water soluble.

Well Ive been top feeding salts last 10 or so days about 800ml.I just filled the res 2gallon with about 1EC of hydro bloom food.Always like doing experiments,will see how she does.Thanks.

My buddy gave me a cut of slazer beam about a month ago, already in pretty much depleted soil. Now mind you, I've never been able to get salts and soil to work right, but just for the hell of it, I started giving it the Lucas formula, and it seems to be working pretty good. I just got to get the watering of it down now.

Just feed to a good runoff low EC never straight water,dont let it get real dry and youll be good.Just like coco only takes a little longer between feeds.

As far as the low ec goes, I'm doing Lucas full strength, and I'm not seeing any to burn.
So I shouldn't do straight water every other?
She's in a solo cup right now, and I give her about 100ml of solution every other day and 50ml of plain the other days. I get a good runoff with that, and if I go much longer she starts to wilt.

Ya if your in a small pot just feed to runoff. Easy to do in solo cup. It’s when you put a small plant in a big pot then you can’t feed to runoff.
Just makes it simpler if you just feed every time to runoff. You can lower EC just add a little more water after you mixed your Lucas.

Ok, but what's your thoughts on lowering ec? Is it because at full strength, I'll get a buildup if I water in everyday? You have a good idea of what ec I should start with? I'm at about 2.0 right now.

I would be at about 1 EC and then feed every two days if it gets noticeably lighter.

Either or is ok. Water feed water etc. solo cup so hard to fuck up. It’s when your in a bigger pot that people mess up they don’t feed to runoff then they let it get too dry then only give it a little water. You’ll be transplant soon no?

Yea, but I believe I might only go up to 1 gallon. I'm gonna keep it for a bonsai mom, so I just want it nutritionally healthy for now.

It was lighter, before I started feeding, I wasn't sure what direction I wanted to go with it. It looked bad. Yellowing leaves, purple main stem. Now the leaves have stopped yellowing, and new green growth. Still has purple main stem though, but the leaves look good.

Mid week 8 in the growboxes. Got some clover popping up in the back on this one:

Crnklz looks like she'll be glad when it's over...I can probably fit one more run in before May/June, when it gets too dank to flower in the basement. I'm thinking of popping another clone into the same Growbox, no added amendments, and train it low/far from the light, and see what happens.

I am using a growbox sip, same.size as an earthbox holds 1.5 cubic feet of soil, I am growing in a converted wardrobe that 40 inch wide and 28 inch deep and 6 1/2 feet tall, I use a big mix of different dry amendments in fox farms soil and water only the whole ride
