Peyote WIFI & Cheese 5x3 grow

Day 1 - 7 L watering with around 1000 ppm and 6.5 ph Day 3 - 7 L watering with around 950 ppm and 6.4 ph Day 5- 7 L watering with around 850 ppm and 6.3 ph Day 7- 7 L watering with around 850 ppm and 6.3 ph During this and last week plants got a few burn tips so I am starting to reduce nutrients gradually and will finish of with 1-2 weeks of R/O water. First Peyote is getting big and is growing new sets of white hairs, Both Cheeses is much smaller and less frosty while Second Peyote is having lots of orange hairs and by the looks of it is only a few weeks away. Still Hoping to harvest all at the same time and will try to time the harvest in that timeframe so all plants are ready. So around 3-4 more weeks seems to be the case.
