High DonCostro, The roots do not get enough oxygen. You need to let the soil dry out before watering again. Your pH is perfect and the soil contains more then enough nutrients for this stage! So let the top 5cm from your soil dry out before you give water again. And try to water around 10cm away from your plant so that the roots have to search for the water and also have acces to oxygen! Happy Growing! 😋

I agree with m0use on this one... it might also be a bit of genetics!

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static
