Still having problems with these afghans.
Need help. Purple stems raised leaf ribs and drooping with a little curl can't figure it out.
Soil is 1 part bat quano, 2 parts earthworm casings 5 parts compost consisting of eggshells, paper, molasses,
Can of beer,chicken poo and rabbit poo made in a compost tumbler cooked for 8 months turned weekly mixed with a bag of perlite and a little potting soil.
Can this mix be to hot?
Grown under a 1000 watt hps
Lights on temp is 75
Lights off temp drops to 62 ,63 degrees.
To cold ?
Watered every other watering with a tea consisting of Alaskan fish and bat quano with manure. Put in a bucket with a bubbler for 24 hours, always phd to 6.3 to 6.5. Any help, and lets not just say overwaterd the pots are light when I water.
