Shes now under 30w of leds
RH is better at least now it stay over 30 /it was around 20 all the time since start../ will try to stay between 6.0 and 6.2 from now on..
Ok, but I won't take any responsibility for the results that way.
The reason you need to flush with high P/K is because in this state, the plant isn't growing, so it's isn't going to take up many nutrients. Which means the nutrients you pour on, will just build up in the medium.
However... if you give the plant Phosphorus
, that goes directly to building lots of roots.
Which means the new roots can take up more nutrients, which reduces the build up of nutrients.
That's why the high P/K.
Also, a pH of 6.4 is more for late bloom, if that, and might cause non-mobile nutrient lockout (mainly trace elements). Most people start off with 5.8, however I've never seen the benefit of it. 6.0
is a nice and easy number, and works very well.
I really suggest you flush the plants again, with a high P/K flowering solution of 0.2 EC
. I've tried and can vouch for: Plagron Green Sensation (0-9-10), Atami B'Cuzz (0-20-30), and Ripen (0-5-6). I'm sure Canna PK 13/14 would also work.
Cheers and let me know how it goes.
