COCO COIR Brown leaves clawing and growth stopped

[bertieboy]

HELP! First time grower in tent with LCD lights, venting, fans, nutrients, etc. Followed all the onlin advice. Started off well but now plants have stopped growing and leaves are turning brown and clawing. Any idea please? TIA

Thank you. Any way you can tell what went wrong so I dont make the same mistake again?

Maybe nutrient burn? I've seen them come back from worse honestly. My clones are a good example, I didn't think they were going to make it but they did. More information would be helpful so we can offer better advice. What soil you're using, water pH, nutrients you're adding and at what strength, temperature, humidity (if you monitor that, I don't), anything you can tell us helps.

Thank you dphipps. I am using coco coir fibre mixed with perlite (75/25). Soil pH is 7. I dont measure air humidity but I have a soil gauge and it shows "moist". As nutrients, I have used only once a mix of Jungle Juice (Grow/Micro/Bloom) with concentration as per the label (and leaves started to go brown long before I started using nutrients). Lighting is LED 600W. I have an extractor 24x7. Only thing is the tent is in my garage, and despite a small heater in the tent, the temperature averages 55-57 deg F so that might be a problem? Any tips? TIA

Yeah low temperatures can be a problem. May be what's causing the stunted growth? I've never grown in coco but from what I've seen you want to feed nutrients every other water.
