    87f day, 75f night 45% humidity, fans at plant level and below with lots of air movement, 1300-1500 ppm co2, 65f res temp, air ring and water circulator. with only me to compare myself to I don't really know if im doing good bad or what. this what we got

    It looks like you are doing well. al of your numbers are right about where they should be, maybe drop a few degs during the day, but them again c02 does make it so you can run higher temp, so you are probaly all set.

    I see some serious nute and heat issues showing in the leaves, clawing and taco-ing.

    bdt1981 Well-Known Member

    can you explain a little more what you see, and maybe a suggestion. I have seen the tacoing what is that from? im not liking the cutting edge at all, it ph's at 5.0 -5.3 after mixed and I hate to add ph up. probably going to switch back to future harvest development. thanks

    and sorry bout the liberty haze all bent over in the pics. it was a free one and It was more in the way than anything. it started with the claws when it grew up past the light. that's why I bent her down

    Adding ph adjusters is part of hydro, accept it because below 5.6 and above 6.2 you are locking out all the good stuff. The clawing is from too much nutes. The leaves that look like dry paper and are bending up(taco-ing) is from too much heat and not enough humidity.

    Canoe leaf is another term used to define this hot condition , its as if the plant has its tongue out and is panting so to say . Your temps around the canopy and especially around the direct area of the bulb is excessively hot . If you can acquire a infrared thermometer you will find that the temps can vary within a canopy . As well I would not go over 85 f as a max even with 1500 ppm co2

    PH levels are KEY to successful growing, ignore them at your peril. Your plant isn't getting the right amount of nutes due to your low PH and because of this your leaves are will eventually dry up and the plant will be beyond repair. Sort the PH out or loose the plant it's has simple has that :)

    Thanks everyone. So when adding ph up do i just need to add it slow or what. In the past i always have but a friend seems to think adding ph up locks out nutrient

    i have one so i read somewhere tjat with co2 90 t0 95 is optimum the comtroller is at plant level and running 2400 watts 2k
    Ontop and a 400 sidelight on each end of a 4x8

    Your friend is an idiot. Get the ph where it needs to be so it can get what it wants. If ph is 4.2 add enough to make it 5.8. Period.

    My thoughts exactly. Thanks for the help. Have you ever heard of ph up locking nutes when I add it to nutrient it clouds up upon contact with the solution.

    Hell no. Dont believe witch tales..btw whats your opinion on LH? I have a ten pack coming over the pond now from sea of seeds. Have seen a lot of grief over liberty haze...

    Pretty similar to my numbers. I can't get it below 90 during the day right now, but they look good... Summer time is just a bitch around here for growing. Winter is easy though.
