I think I am having the same problem that I had last run.
fan leaves turn brown as pic shows.
I messrued PH and EC last night. can tell the PH and EC swing a bit.
The one that I did not do defoliation shows more signs of deficiency.
two days ago: PH5.9 EC 1.5 last night: PH6.1 EC 1.2
The other that I defoliation do not have much sign of deficiency, but that one I amlost took all the fan leaves off already. I can see some left fan leaves show some sign of deficiency too
two days ago: PH 5.9 EC 1.5 last night: PH6.2 EC 1.8
use tap water EC 0.1
I use GH flora two part mix with 1:2 Micro: Bloom
Koolboom liquid 2ml/ gal
I used to follow Lucas formula. go 8:16 ml/ gal
I can only get my EC to 1.2, I think a lot of guys here go much stronger EC than that
so I simply just fellow 1:2 and go more then 8:16 ml/ gal
EC 1.5 would be my base nutrients. after adding koolbloom EC raise 0.1 to 1.6
Am I feeding too much or they are actually hungry.
I know if fan leaves turn yellow in last few weeks.
Im 34 days after flip, still feeding them. fan leaves should not turn brown or yellow this eari
this is my first run running 600watt hid. I can tell buds fatten much faster then 400watt.
Want to get everything right to have good yields. Any feedback are appreciate
happy grow
