No worries man! Looks like they took to the nutes quite well. Gave them about 40% or so of the recommended dosage. I have found out that my soil mix is fine, however it tends to dry out quite quickly. I have to water them every day and a half or so, however I don't think it is that big of an issue at the moment. The 400W is about 45 cm above the plants and I am thinking I will just keep it at that height for the time being. The nutes were Plagron Terra Grow. Will do another week or so at 50% and then increase the dosgage.

Best!
