Plants looking happy and strong there!
@hope2grow - question on your feed schedule I've been using. With the Sensi Bloom only, do you feed every watering or do you follow a feed, water, water schedule? Ive been on the feed/water/water and it's working unbelieveably well! (Also apologies for cluttering up your thread)

@Taipan - I see you guys discussing the UV add-ons. There was a bit of discussion in another thread a while back, Ill see if I can find it, but.... the main TL
R was to make sure you've got UVA and UVB. So far most of the LED solutions can only put out UVA wavelengths and fluorescent T5 tubes can effecvtively produce UVB and UVA. Cost wise a T5 tube lamp is the best cheap fix for UV spectrum at the moment. There are some high end LED UV strips but they are still £££ and DIY.
The Migro appears to have the right spectrum spread for the "right" UV response from the plants. Nearly £100 is steep. I picked up my 2' single bulb T5 for $50 shipped. I don't think the place I used ships international though. I don't know how difficult the plug conversion might be for UK/EU, the Migro after all the shipping, customs, plug swap is likely just as much money and easier.
I got mine here: Just hit the edit to pick the right bulb you want.

UV Light Benefits for Cannabis
Aside from increasing THC content, UV wavelengths have other benefits. UV-A light increases anthocyanin content while UV-B light increases the amount of lycopene, beta-carotene, glycosides, and hydroxycinnamic acid derivatives
(Li & Kubota, 2009; Neugart et al., 2014; Pérez et al., 2009). These compounds can change the color, flavor, and smell of a plant. These changes in color, flavor, and smell often make plants more
appealing to humans, but more toxic to some insects. Plants with increased levels of these flavor/smell compounds are less likely to get eaten by insects
(Rechner, Neugart, Schreiner, Wu, & Poehling, 2017)! This means that ultraviolet lights can decrease herbivory from pests. Lastly, there is strong evidence that UV-B light prevents the spread and severity of
fungal spores (Palmer, Drees, Foster, & Lindner, 2018).
Ultraviolet light is useful for more than just increasing THC content. As a grower, it’s important to weight the benefits and costs of using UV light to decide if it will significantly improve your grow environment.
