Hey guys need help.. running a aeroponic system using recomended nuts. This is the second time im getting leafs with brown spots and spreading.. this seems to be affecting only the WW and the JH.

i tried flushing with florakleen and after 24 came back with 1/2 the nuts and still have this problem.. using calmag..and bio bloom too.

6 week of flower

Water temp 68
ph - 6.0 - 6.2
temp - 68 - 70•F
ppm- 1100

Ph is always above 6.0? Manganese deficiency. https://www.growweedeasy.com/cannabi...ese-deficiency

You need to let ph flux between 5.5 and 6.5 or you wont absorb the full spectrum of nutes. Manganese is locked out above 5.8 and calcium is locked out below 6.0

Tersky, could it be over watering.. im in south america and couldnt find a timmer that goes down to seconds.. so i was spraying 1 min/ every 30 mins..

Ok. Well i hand water so dont know anything about timers for auto feeding systems but still it is showing signs of Manganese deficiency which will happen if you dont allow you ph to flux. The leaves are not showing signs of over watering to me, just deficiencies.
