calling all clever clogs... what's the problem?

[Hippy_BiotabsF70]

Ha ha. Just found a couple of your posts. You are happy and stoned. I'll raise light tomorrow but now I'm gonna crash. Cheers for your help and banter. Big up.

Night bro

wooo! 110w COB's? that's crankin' the juice there,... I agree, it think you're getting some light intensity stress, if not direct heat,... this proximity intensity overdrives the whole cellular machinery and transpiration, so the plant pumps the water and along with it, nute elements up to those leaves to try can cool shit down,.. this build-up of localized nutes can cause what looks like K defc. (or toxicity in K's instance) with the burned or yellowed margin teeth,... up curling is tell tale as well,... Do you have a dimmer on the COB's? Raise then another 8" min. if you can,... I'm not that hip with COB's yet, so maybe @BigSm0 can chime in on the deal with the COB's wattage and distance placing,... is this a DIY unit, or manufactured?

Definitely needs a lift. I have been seeing more and more problems with cobs being to close. The low wattage leads people to think they aren't as strong as other eBay specials. What's the wattage per sq foot? I'm currently at 30wpsf at 30 inches

Sm0, isn't 110w quite a lot? My 75w CXB3590's are like a damn strobe that just stays on! I can't imagine what 110w is doing,...? or wrong equivalence there?

It's definitely a lot no matter how you slice it. It's like a mars hydro 600 squeezed in a 28mm chip.

Wow, thanks @Waira. Good answer that absolutely makes sense. I've dimmed it down to 100w and raised it up to 30". Yes it's a home made light and completely different from what I'm used to. I used to have a 75w hs1 that I would drop to 20cm or less when in flower just to get the intensity.

@BigSm0 I've raised it to 30" and 25w per square foot. I've got 6" of headroom left so glad I kept the auto glueberry short. My next seed is gonna be auto blueberry, an Indica dominant strain and was gonna grow it naturally without any lst. Gonna buy some rachet ties and strap it down as hard as I can now. Lol.

If the tips shoot straight up then you know they had to much Light beaming down. Just keep them under watch and I'm sure you'll be fine. @Waira I don't think there is anyone who knows plants like you do man. Afn is lucky to have you.

Leafs pointing up so nice healthy there, buds forming nicely, temp and humidity in check, 110w cobs @ 24", so what causes the leafs to look like this?View attachment 694604

Not sure that the light is not causing it, but it looks like you have a Mg def developing. A few of the pics appear to have whitening between dark green veins?

Suppose it could be the mg but I doubt it cos I always put a good glug of calmag in the feed.
