4 week old plants are drooping

tomjhannon · Jul 12, 2025

I have six plants in my grow house. I planted them about 4 weeks ago and they were thriving. I tried using co2 bags and 10 gal bags and the results were amazing. They grew 18” in 3 weeks and the leaves are huge, some about 10” in diameter. Yesterday I gave them a little trim, just the bottom area and a few leaves that were blocking the light. Nothing heavy. I came out today to feed them and found them drooping. I’m not clear in why but I suspect it was the trimming. Here’s a pic

What time of day was it. My plants pray during the day, but droop like that every evening before dark. Been that way from the day they went into veg, outside of being seedling.

Just thinking

Looks like you reduced the biomass without reducing the needed water. Turn down your irrigation a bit, adjust as needed.

No change from light to dark. It happen after trimming them. It looks like to much water but I’ve been doing the same thing since the day I planted them into pots.

That occurred to me. I don’t have any irrigation on the plants. I water by hand every three days and only feed them a gallon each. I checked them today, they are still drooping but otherwise still kicking.

Wait til top 1/2" is dry between watering

Better yet, IMO, is wait til the pots are light. Try to get a feel for how heavy they are just after watering compared to a dry one. What size pots are those in? When I transplant to final 7 gallon pots from one gallon pots, it can take up to a week before the soil dries out enough for another watering.

I have ten gallon pots. I am going to wait a while before watering. I haven’t used the ten gallon bags before so this is the learning curve. They don’t dry out as fast as the five gallon buckets. Also the temp has been about 80 in there so it might take a bit.

I placed extra plastic straws from my Stanley thermos around my last crops in soil, to give the roots extra O2, good to aerate.
I went back to hydro, DWC actually. I water 24/7, 24hr light fer veg.

I pulled them up. They were too far gone. I have new seedlings planted already. I think it was from the co2. They were unrecoverable.

Sorry for your loss

I don't use co2 but from what I read or heard, you don't really need it. Unless you are pushing them hard during flowering with intense ppfd. I may be wrong though

I got sucked in with all the hype. It was a failed experiment. Live and learn.

I use dry ice in mid-late flower, it's fairly priced here and helps cool down the tent.
