First grow

Well it's the first day of week 5 and they are growing very well since their defoliation and lst, I know its only been a few days, so I won't see much changes. After a couple of days went by I decided I needed to do some more defoliation as some of the leaves I left grew out to big fan leaves that were covering the flowering ones. Only been watering with water so far as they had a good dose of nutrition during week 4, will leave them on water for a few days then start back on the feed. Day 2 finished and it looks like they are just finishing their veg cycle and starting to show some signed of flowering. I do think I have made a mistake with this week, I don't think they are in vegetation they seem to be in their first week of flower even though the white widow seems to be a bit behind the amnesia as the amnisia shows more signs of being in flower than the white widow does, I will keep you all updated on how the next 3 days of week 5 are going. Week 5 has finished and they look very well, but I did see some strange brownish/reddish spotting on one of the leaves can anyone tell me what this means I have added a photo of this.
