Beginner growers here! We’ve just sprouted four new autoflowers and we’re beginning to wonder if our soil mix is adequate as far as their needs go.
We’ve just recently had two plants fail to get past the seedling stage- they eventually drooped, yellowed and slowed their growth until dying.
Our stats as follows:
- Strain: Gorilla Glue
- Type (fem/auto/reg): Autoflowers
- Climate (indoor/outdoor): Indoor
- Medium (soil/hydro/details): Peat Moss, Compost, Perlite, Vermiculite
- pH of runoff or solution in reservoir: N/A
- Nutrient mix strength (EC/TDS): N/A
- Light type & schedule: 18/6
- Temperatures day & night: 22 C/25 C
- Humidity day & night: 40%-60%
- Ventilation: Yes
- AC: No
- Humidifier: Yes
- De-humidifier: No
- Co2: N/A
The soil we’re using is a combination we read about from a few sources on the web (Zambeza, GrowWeedEasy), and this is the part we’re really curious about:
3 parts peat moss
3 parts compost
2 parts perlite
1 part vermiculite
And that’s all that’s in it, no “boosters”, not extra fertilizer, nothing. We assumed the compost would provide all the nutrients they could need for the beginning stages, but they seem nitrogen deficient after a certain point. They’re doing okay for now, but we would hate to have the same thing happen again. We’ve been very careful with our watering schedule and we’re convinced this isn’t an over-watering problem at this point. They were germinated/planted at different times and are between 1 and 3 weeks old.
