Northern Lights Auto x 2

An explosive week in comparison to the last 2. Planting straight into their final big 12 litre pot always starts slow however after a few weeks we see explosive growth which fingers crossed will continue. Without the need for transplanting into another pot the plants should continue their fast, strong growth. There is a small look of a possible magnesium def which apparently isn't uncommon when growing in coco?? I will be adding Cal Mag into the feed this week and will continue this throughout the grow if I get no further issues and upping the strength of nutes. Switched back to the 1000W LED, plants are responding well however the humidity is very low. Not sure if this will or is a problem however will tackle and issue as it arrives.
