First week, just trying to get all things work, nothing really intersting to say.
i'm in a closed loop watering system
watering :
d+1 : i made my solution to reach 1.5 EC, drain came at 1.32 EC
d+5 : ajusted solution to 1.5 + 0.18 (compensating) EC, drain came at 1.17 EC
topping all of them at d+9
watering :
d+9 : adjusting to reach 1,5 EC + 0.33 EC, drain came at 1.51 ! it means that they absorbed nutrients as much as they absorbed water.
The lower big leaves are coming yellow, and curling down and looked like "overwatered" but i dont think it is.
Maybe nitrogen deficiency ? or too hot ? could be a pH problem ?
I've had my one plant look like the 2nd pic in your question.
The temps and lights where fine, I'd say this is more of a PH issue.
granted the canoeing of top leaves tends to be light and or heat stress.
Your diary says your running a PH of 6. That's on the high side for veg in hydro.
I'd try lowering that down to 5.6-5.8 then back up aorund 6.2 in flower.
your PPM is also a bit high for week two. I'd try lowering that down by a few hundred and then raising it slowly in the next week.
the GH trio line runs hot from what I've been told.
Best Of Luck!
everything's pretty fine. only one problem, I touched the timer before leaving home for 3 days and I didn't saw that I switched it from the timer mode, so they got 3 days of nonstop light, hope this will not affect much.
added green sensation
Got a little deficiency, can't find what it exactly is.
Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days
Begining of nitrogen toxicity, cut back on nitrogen now that they are flowering.
Also, always post pictures taken in normal light, pictures under grow lights are next to useless for details.
