Wow what a painful week. They're all stunted seedlings and haven't grown in a week. The 4th didn't germinate for the 2nd time.
So I've been doing nonstop research and asked a question on here.
Overwatering can cause this, but I am not overwatering. I water with pH 6.2 with a 5ML dripper that is used for nutrients. I let the soil dry out for 3 days. No improvement.
I think it's the soil pH. I know these probe testers suck but it did work yesterday. I put it in my pHed water and it did show the correct pH, but today it won't.
It's Espoma Organic Potting Soil, and added extra Perlite. Crappy pH soil probe reads almost 8pH.
What can I do here? Can I try to flush them with 6.0pH water to change the pH? Could I add dry nutrients or acidifier to change the soil's pH?
#1 looks the same as 3days ago. Their first set of leaves and new growth are light green and curving downwards. Should have bigger and next set of leave? Tested pH of purified water I used and it's a bit high at 7.0. I dimmed the light to 25% from 40. Other ideas?
Hey there Jabz, you're right to spot this as a problem. So this is due to overwatering. What happened is that humidity got trapped towards the center of the pot and water mold appeared causing root zone issues which in turn causes the droopy leaf symptom. You do need to stop overwatering, probably you can wait 2 to three days between waterings. Try the lifting pot method to never overwater again : www.youtube.com/watch . Then keep monitoring the plant, just by following a strict wet/dry cycle the plant should fully recover quickly, but if it doesnt what happens is you have to break down the problem roots with a chelation agent like humic acid or enzymes which are common cannabis products. Hope this helps ! 🚀
Help these babies please! Watering very little when dry with 6.2pH. I can't get these growing. Should I flush? Transplant in different soil? Add nutrients to lower soil pH?
Hey!
Plants need way more moister in the first weeks of life.
If the soil is constently dry they take longer to grow.
Don't over water but you're definetly under watering.
I would take the PH down to 5.8, at this stage nutrients are better absorbed at that PH.
If your using a light or heavy mixed soil, you don't need add nutrients until 3-4 after being planted.
It does look like a bit of Nitrogen deficieny but it could be because of the prior mentioned stuff..
I recommend you water more, to give more moister in the roots and fixing PH, RH seems. fine.
If that doesn't work add a bit of nutrients.
Hope this helped.
Good luck and happy growing!
