I'm Ready- Blue OG, White Lavender, OG #18, and Sour Kush.

What is the white on the leaves? Is that powdery?

Hey guys. Lets figure out what's wrong with GS3000 Bubba. Here are the details...

Please check out my Bubba Kush. This is day 39 since 12/12 flip. I noticed a leaf problem at the top of the cola some of the pistils are turning brown on the buds. Is this normal? The leaf problems are just on the top of the cola the rest of the plant is still nice and green with no signs of trouble. I moved my lights up some from the plant just in case it was too close and burning the plant,

Here's the link. Bubba Kush - 26 Days since 12/12 flip CFL lighting FF Trio nutes

I'm feeding Fox Farms Big Bloom and Tiger Bloom. Feed about once a week. Feed let it dry then water with Ph'd water let it dry then feed nutes again.
Not sure why it;s isolated to the cola's top leaves. I have two fans working air flow, I let my fans run during lights out also. It is just the top set of leaves no ther leaves on the cola is affected.

7-9 weeks and they are at day 40 since the flip. Thanks for your help.

You didn't give a lot of information about your grow but that looks exactly like heat damage from getting too close to a light. Especially since you noted it was always in the top of the plant. Light proximity along with low humidity and/or fan blast can burn tips like that. i.e. you can have your bulbs at a reasonable distance, but if you get a day of really low humidity with some fans going, and the soil was dry to begin with you can burn the tips. Basically the plant is losing more water from those tips than it can provide. Only takes a couple hours.

Really does not look nutrient related but diagnosing plants long distance is tough.

Anyway I can say I've singed a few tips and thats exactly what it looks like.

A lot of reading isn't it Bakatarre?

Lol, i'm getting your "like" notifications as you going through the thread.



Thanks for the input AimAim.

with out knowing all the details, just from the pics I must agree, heat stress, edges of the leave`s is curling up, a sure sign

lower the temp`s move the light up a bit

Grow #2. My first grow was harvested back in March. Ended with nine oz. of dried bud from the four pants at about 9.5 weeks into flower. Here's is my bud porn from the last grow. Some of you guys will remember these shots.

Why do you have to everything so fucking organized and make mine look like a junkyard?

Slipon said:

yea, well its not me in the pic, just one I found online, and did never try it with joint`s, we used a carrot, made in to a chillum/pipe, the fitted in a hole in the melon

Buddy of mine used to do watermelons sitting on his roof during parties and toss them overboard when somebody would get too rowdy.

Well, I missed out on a lot at the start, and it wouldn't be fair to just jump in and start tossing out ideas without actually knowing what I was looking at (which I imagine happens a lot).

I like having you guys around so I can make you feel like shit. It makes me feel better about myself. A true friendship.

I've seen your grows - you guys are green thumbs! I'm just weird about organization. It's a disease man.

Thanks I think that may have been the problem. I have a fan sitting at the bottom of the box and another fan at the top. So with the fan blowing on the top with the lights going, combined with me letting the soil dry is probably what created this situation. Probably dried out the top leaves. I should re-position the top fan and and have already raised the lights some. You think i need to add moisture for humidity? You are right it's probably getting to hot and dry at the top. I think the white powder might be from the water. I have been using baking soda to raise my PH. When I add the nutes to my water the ph goes to about a 5 and I use the bk soda to raise it back to 6.5. My water from the faucet is about a 7 and I use vinegar to drop to 6.5. I think the white might be BK soda coming thru and showing up after the evaporation process on the leave. Probably another newbie mistake. Open to better approaches.

thanks a lot !!! I don't know if I should try to up my game or just give up

Looks fantastic and your temps sound fine. It's not the same as a plant all of a sudden expierencing higher temps. As long as its pretty consistent throughout individual grows you'll be fine. I sometimes run the flower room up at 87-88 with no problems. That was in the expieremental stage and now usually have it at 80-81 day and 72 night. Ps I just realized this was a response to your first page and has already been answered multiple times. Haha I'm a fuckin idiot don't mind me!! Later and yea to be more relevant, it could be related to spraying down the plants and water remaining on the plant and then burning the plant. But what the f do I know? Heh later.

I wouldn't worry about the coloring of the hairs so much, but though I agree with Aim about plant moisture, I am leaning towards nute burn, due to the fact it's starting at the leaf tips and working inward.
I have burned a couple times, and it doesn't necessarily always start in a particular area of the plant.(meaning top or bottom)
What I am concerned with however, is the white spots.
With your humidity is down and you have good air flow, I don't think it's fungal.
ANY possibility your room might have picked up something that is leaving poopies on your leaves?

Hey Slip, your inbox is full. Here's my reply...

Np. and Im off work for a week a little early presumer vacation you could say (had a little left over so to speak)

Cool, enjoy your movie and thanks for checking in with me. I thought I read that you are a metal smith? I'm medicated so I could totally be wrong. Maybe it was all the fabrication I see you do and put the two together? I use to work in my Dad's shop in Texas. Summers would get up to 120 degrees in there. A point where the tools would be too hot to touch! We would flip our schedule and water ski in the day and work late night into the morning. Miss those days.

lol I always forget to delete em

and your right, Im a metal smith, in my early years I worked at a shipyard, heavy work, in the summer time we had to changes overalls 2-3 times a day, soaked in sweat, you try to be in a 3x3x5 ft metal room welding with overalls fresh air/welding mask, cables/crinders and whats not and its 90ish out side in the shade

now a days I make machines in stainless steal for the medical industry, much better, less work, less dirty, less risk, and more money

The white on your leafs look like residue from water evaporating after you spray. I get that too if I don't filter it through a brita, it's a pain in the ass but the girls love the extra care. With reading the situation the best i could I would say yes probably just some heat issues with arid soil and dry air. It can happen fast and to the best of us. cannabis can take really extreme temps as long as they are ready for them per se. Good luck bro hope you sort out your problem. out.

lime in the water will make mark`s on the leave`s but tell me, why spray em in flowering ?

if it is some kind of PM/mold (like if it spreads) I would look in to some H2O2

PM (powder mildew) dont need high humidity to trive, if you get the spores in your grow room they will attack the plant, PM trive at the "right" temperatures, and unfortunately its about the same as we want in our grow room, PM is a tiny spore that come from the outdoor environment at the "right time of year at the "right" temperature`s

for now keep some good air circulation and keep a eye on em

Thanks guys for all your help and suggestions. I haven't sprayed the plants. I think it may just be left over residue from when there was too much humidity in the box. I would open the box and the inside of the panda film would be wet, I think the box was closed to tight, but I have taken care of that problem. I will keep you posted.

dehumidifier for the win. Also looks like either nute burn or heat stress. I think this has already been addressed...but oh well.

Hey goose, how's it smokin? Just wrapped up dinner and was checking back in with GS3K. Made my curry meatloaf with garlic mashed potatoes, oh yeah, it's that good!

Dehumidifiers are nice to have around just in case, but it also comes in handy for the curing later on. Looks like a lot of folks have responded. That's cool.
