Well I added 280 ppm nutes and she showed signs of burn and the leaves dropped. I lowered the ppm to 200. Is that good enough? It's a very small amount of brown around the edges but I dont want it to get bad.
That kind of burn around the edges of the leafs is usually related to magnesium deficiency, so make sure you're adding micro to your mix . there isnt one single level for PPMs, just follow and respond to your plant. Hope this helps 🚀
At this stage of growth you should be around 150 in general. For the first 3 weeks its not a race and if anything it's better to give them slightly less as too much nutrients early on will mess up your entire grow when it comes from running autos.
