Hey Kritical, Excellent room setup and great plants.
One thing, back on page 4 or 5 I noticed an air pump in your room.
From what I understand its a big mistake to have an air pump in a room with co2. If that is the case, best to move it out where it can get some oxygen.
Best of luck with this super grow.
1) where on the plant were these leaves located
2) can you take a picture of the affected leaves while they are still on the plant
3) have you noticed any discolorations or pH / ppm fluctuations in the last few days?
also, the plants are starting to compete for light. if you feel confident, try to bend some of the branches using LST so that way they do not wrap over one another and allow them more light exposure.
in the post above, your pH's say 0.00 to 0.00. can you put them in again?
680 ppm down from 750
5.70 ph up from 5.00
water level 4" low
room temp 75
room humidity 60%
res temp 66
co2 ppm 300
room has too much humidity to i opened it up to let it breath and turned off the co2 until i can get a dehumidifier today. looks like my only option is frys.
i took a good look at the smallest plant that i super cropped and that thing has healed up nicely. it took a couple weeks for sure to get healthy again but theres a nice knot where i broke the main cola. but the church is so bushy already that i dont think it is even needed.
and see you got the dehumidifier in there, good move. still, 60% is too high for flowering, as you run the risk of bud mold exceeding 50-55%; 45 is ideal. have you noticed any spider mite resurgence since flowering began?
Also, now that you are in flowering, instead of listing day 49, can you list the days you are in flowering? I believe its day 3?
