This is the 3rd time I’ve grown in a tent, 1st time with LED and first time with fertiliser. The first 2 times I used a HID light and coco peat + nutrients. It’s a 1x1x1 tent with 4 14L pots filled with 4 different fertilisers. Any suggestions and tips for the future would be hugely appreciated. Thank you.

I may not be the one who can answer your questions, but it would be helpful if you could post pictures of plants in natural light or just light from camera flash. Also it’s not clear if you are growing in Coco now or soil. You say you are using 4 fertilizers. If possible fill out support ticket it will help to diagnose the problem.

Not liking the looks of your soil, looks like one those “Will feed your plants for 10 years” type with time release ferts and no perlite. Wrong soil, try a Fox Farms Happy Frog or Ocean Forest.

Are you saying that mixed these 4 soils together or you are using each one. When growing cannabis indoors you need to provide very specific nutrients at different life stages. It’s difficult to see what is happening with the lights on. From what I can see it looks like your girls are probably getting nutrient burn. Most likely the soils you are using are time released and are burning your plants up. Please get a picture of plants with natural light or with just flash from camera. We’ll start there.

I am well aware of how good Fox Farms is, but I live in Australia and do not have access to them.

30c and below 40% humidity is to warm and dry for this stage 75-80f and 60RH and above are some good numbers

Looks like your overwatering, which tends to cause nute burn as well with time release ferted soils, because every time you water, you’re releasing more ferts. Need to back off on the watering and let them dry up mostly before watering again. Try to find some potting soil without any time release fertilizers in them or any ferts at all, that way you control it yourself.
