ANYONE PLEASE HELP! Wtf is going on !

[Muskegman]

Straight and to the point. I'm doing my first scrog. Blueberry and blue dream. I'm using 2 600watt HPS and one 600w G8 LED. I vegged for 60 days, low stress trained them until I put the net on them. I have 6 plants all together. I made subcools super soil, with everything except the humic acid which I couldn't find. Anyhow, everything had been going great until I flipped to 12/12. It's been a week now since I flipped them. It's only on two plants but it's getting worse for sure . I cant figure out what is going on. Too much water ? Too much heat ? P over dose or not enough of it. PH issues ? I used fox farms ocean forest and pro mix BX as my base soil also and they been in the 7gal pot for over a month so I know they've grown into the super soil for a while now. I don't know the PH of the soil but I'm going to check it tonight. The water in giving them is 6.0-6.5. Temp is 75-80 and humidity is 50%. I'm growing in 7 gallon black plastic bags that are on top of milk crates off the floor with good air circulation. I have two fans going that seems to keep them cool enough. They started showing signs of wilting sort of , then little dots , then leaves curling downward, which ends in entire leaf dying and drying up . It's only doing it on two plants but I don't know what the hell is going on and don't want this to spread to other plants if it's a disease. I just watered them on Monday. Should I let them dry out and start to droop , then flush them ? Maybe give them some voodoo? I hope someone can help, it would be so appreciated! Thank you and good growing

 

[justsmokedope]

have you got a ppm meter to see if you have over fed them , if you cant test it just flush with fresh water,
how ever some leave will fall off as the plant uses there energy to make bud etc the leave will thin out etc is it all leaves or just some if its just some id just keep an eye on it .. if you in the uk and with the waether we are having it might have got too hot and dryed out your pots too much casauseing a concentration on nuits etc

 

[Muskegman]

I'm not adding nutes. In using just water , rain water with a ph of 6.0-6.5
I'm using subcools super soil recipe so it's only water . I'm starting to think its a PH issue ,blight, root rot, over watering, or potassium or phosphorus issues. I just don't know

 

[*BUDS]

I cant give you an answer until you show the whole plant.

 

[Muskegman]

It's mostly on the top leaves. This is a scrog with 6 plants all together it's hard to get a picture of the entire plant. All I have is the tops comin through the screen and the leaves look like the pics I posted . Everything under the screen is lollipopped, so what leaves I have above the screen look like that . I checked the soils ph tonight and it was between 6.5 and 7. Not sure if that's too high for soil . In case it was blight, I made up some home remedy I read about. Equal parts baking soda and vegetable oil and mix in a gallon of water and spray plants and infected areas. Gave it a try , I'll see what happens now.

 

[Joe Blows Trees]

That's an interesting mixture. I'll be looking for an update in hopes you remedy this issue.

 

[Alienwidow]

Feed it some calmag. Looks like you ran out of oyster shell or whatever you had in there for calcium. I dont see mag def but liquid calmag works faster than powder, and you can always use mag in flower. Look into calcium, it looks a lot like the dots you have.

 

[Muskegman]

I have cal mag but reading the npk vales, it has 3 for nitrogen. I'm using subcools Supersoil recipe and I'm afraid that if I give it cal mag, I might cause nute burn. Any way of just adding calcium and Nothing else fast ?

 

[Dumme]

Gypsum and Epsom salt, then..

 

[Muskegman]

Thank you !!!!

Botanicare has Cal/Mag that doesn't raise PH. It's organic as well. I'd def say Calcium since it's starting at the top. Dolomite and Oyster shell is what Sub-cool puts in there. Did you skip out on the Lime?

Figured I'd update y'all who care lol . Everything is going great . Sprayed the plants with the homemade blight mix, which was 1 tablespoon vegetable oil, one tablespoon baking soda and mixed with one gal of water . And it worked . I'm pleasantly surprised . I'm about 24 days into flower using subcools super soil and I'm VERY PLEASED. Growing faster , bigger than last grow at 24 days, and WAY frostier . Can't wait to see final stages. I'm doing SCROG for first time. Learned a lot, have too many plants so couldn't spread them out as much as I wanted , so some I had to let grow through screen instead of tucking. I'm growing blue dream, blueberry, and purple kush all under one screen 4 ft wide by 10 ft long. I have a 600 w HPS , a G8LED600 in the middle and then another 600w HPS at the far end which will be a MH for a couple days towards the end to see if I can pack on the trichomes .

Very impressive

Update: more problems are happening now. The top part of my buds on one plant is doing some weird stuff. Four buds out of about 12 on this plant are turning yellow and brown, and curling upward. It's the very top of the bud , and goes down about 1 inch. All the sugar leaves are green and look great, all of a sudden the top one inch is some of these buds look like they are dying . Possible root rot ? Never had this problem before . It's my second grow ever. I'm using subcools Supersoil. Didn't add perlite as it doesn't call for it . I will next time to be safe, but it might not even be root rot. I don't know. This strain is blue dream, I'm on day 40 of flowering today, and have about 3 weeks to 4 weeks left , according to the flowing time I looked up on blue dream. Maybe y'all can help diagnose/ treat this. The temp in the grow room is warmer than I want it, at 81-85. The humidity is never over 55 as I have a dehumidifier going . I have one 8 inch intake fan, but no outtake fan. I'm going to install an outtake fan tonight to cool the room down . I would really appreciate anyone's knowledge . Here's what they are looking like. And here's what other buds on the same plant look like. One looks like it's dying , one doesn't .

 

[Big boy roy]

Im no expert but it looks like bud rot carefully pull one apart and see if there is any mold in there personally i wouldn't grow without a extraction fan its not worth the risk all that effort and get mold near the end . If it is mold cut the affected buds of and do it carefully because the spores can spresd very easily to thhe rest or your buds but besides that your grow looks very impressive good luck

 

[coreywebster]

It could be bud rot, looks like there are a few tiny sugar leaves browning which could be because there is rot on the stem inside the bud. I hope not!
Why do you have an intake fan and no outtake? . I have never heard of anyone doing this before.
Your bringing in cool fresh air but not really removing stale air, it will be leaving anywhere it can due to the positive pressure but you would be much better off doing active extraction and passive intake. How many of those oscillating fans do you have in there @Muskegman

 

[Roger A. Shrubber]

theres a product you can get at most garden centers, a foliar spray called yield booster, for tomatoes, stops bloomrot, but it works great if you have a Ca shortage, which is what it looks like you have

 

[Muskegman]

I didn't have an outtake cause I rushed everything and figured that if I had fresh air coming in that was good enough. I'm a total newbie so that's why mostly. Last night I cut them off carefully wearing rubber gloves and put them in a ziplock bag. Where I cut them off at looked green at the stem. I then left the room and broke them open to find grayish white stems, that broke very easily and were kind of mushy. Bud rot correct ? After that I installed an outtake fan. As far as fans go, I have one oscillating fan going , along with one big fan in the opposite corner of the room. I'm open for any kind of feed back concerning the setup . Should I have intake and outtake going with lights off . I have everything off during lights out except my two fans and dehumidifier. If I have the intake going I would assume it would counter act the dehumidifier , and if the outtake going , light comes into the room . I have a 90 degree pipe coming out of the room and it's painted black inside but light still comes in, that's why I have it turned off and have a towel stuffed up inside of it to block light .

 

[Roger A. Shrubber]

you could put another 90 painted flat black inside on the end of the one already there, might be enough. sounds like you already have a lot of air movement and a dehu, not sure what else to suggest, just keep the room as clean as possible, wipe things down with bleach, maybe get some copper antifungal and spray it on surfaces between grows?

 

[dabhe4d]

yeah thats bud rot you have described.
id check over all the bud inside. I wouldn't be surprised if there are more rotten buds around.
