Mixed autos Mamba, Critical and Diemos

It's been a pretty shitty week for weather so plants have spent most of their time indoors. I've also discovered I'm adding about 50 times too much nutrients. Should have read the bottle instead of pouring the stuff in casually..... am using strong nitrogen mixed with concentrate guano. I have been moving all plants outside in their buckets during the day so they get sunlight and then 1000w LED through the night but have been advised against this if I have 1000w LED. Should rather just leave them indoors to avoid stress.
