I'm going nucking futs trying to figure out this issue!!

[NEVER OUTGUNNED]

thanks for looking! been growing perpetual for a couple of years now with 99% success rate bur this blue cheese strain has me stumped! grown it several times and it's hit or miss.

*3gl pots,with royal gold Tuper coco

*top drip feeding every 3 hours in 3x3 trays, x 8 plants vegged 4 weeks, 1000-1300ppm, ph.6.0

*temps 76-81 at canopy level, in sealed room reaching the higher number when c02 kicks in for 1500 for 20min every 2 hours during flower

*hum 50-70 higher number reached during light off

*2600watt hps, hortilux bulbs

*house and garden nutes, bush master 1stweek (they can get out of hand sometimes), big bud 2nd-3rd week, bloombastic 4-5 week, overdrive or shooting powder from week six on.

Now for the problem, i keep getting these burnt ass leaves that look like nute burn but i find that hard to believe at a 1200-1300 hundred ppmpm solution? i have grown recycled this strain several times and it's hit or miss on the outcome without much variance my technique,
thought it might be the bushmaster;however "Bush Burn" 2 weeks after i stopped using it, doubtfull.

looking for some expert opinions from my fellow growers, and ideas would be helpfull/ heres some pics of different top leaves..nasty. sorry about the hps light in the first pic, didnt want to disturb the light ballast

How much runoff are you getting when you water? DTW or recirculating? 12-1300 is a bit high IMO. I've had best luck in coco with ppm no higher than 1000 and no more than one flood a day. When I handwater coco I treat it like soil and only water when it's dry. Lots off runoff is good.


Oh, and why the Bushmaster on your bluecheese? It's a compact strain naturally, have you ran it without the BM ? If so what was the diff?

 

[NEVER OUTGUNNED]

recirc. shit bro, i have used slightly higher ppm's on this strain and have had some awesome harvests, as well as shitty harvest. once a day would kill my plants in a matter of days, between 8 plants they guzzle 2-3 gallaons from a 10gl res every night. blue cheese isnt compact bro, of the strains i have this is one of a few that grows crazy tall, hence the bm.

 

[superstoner1]

that looks more like ph issue than ppm issue although i will say your ppm is high. even though you may think a strain can handle a high ppm i have proven on many strains that less is more.

 

[keep it real.]

thats weird almost looks like a zinc dif

 

[MadmanStitch]

that looks like extreme nute burn...

 

[Capt. Stickyfingers]

Too much nutes w/ excess salt buildup. Flush flush flush, and lower your nutes to around 400 ppm.

Just trying to help, I never have shitty harvests. You are loving your plants to death.

i appreciate it total facestabber, didn't mean to come off as a prick, I'm just baffled by the fact that i can have an amazing six star harvest (this is my number #2 strain out of 11 that i cycle) one cycle, than have this outcome the next without having changed anything.
i run co2 every 2 hours for 20 min, i also wondered if co2 trapped in the 3x3 tray(heavier than air) when flowing downwards, might be effecting the roots since they absorb oxygen....just another theory.
im giving it a heavy flushing right now and im going to lower the nutes to around 1000 from the previous 1250-1300ppm, its in week 4, so while it took a sever hit i think i can still pull a decent harvest.

Not only are you overfeeding you poisoned them with bushmaster (just noticed). That shit is strong and should only be used at an 8th of a dose. It will fuck your plants over good if you follow the directions.

 

[NEVER OUTGUNNED]

i cant ephamsize enough how i have had the same routine for the last 2 years. nothing has changed so its a little presumptuous to assume that they are being overfed or that i don't know anything about the bushmaster and its strength.

If it's a new batch of coco, it could be sodium causing lockout. I do feel that your PPMs are at redline, and a small influencing factor, like a bit of extra sodium bleed from the medium, could be making your plants' figurative valves float. Are you draining to waste or recirculating/reusing? cn

Then don't ask for help. You've been told how you're fucking up, if you don't want to listen, then suffer with shitty plants and weed. You ARE overfeeding and your plants absolutely look like they've been poisoned with bushmaster. But of course, you're doing nothing wrong. Lmao. Have fun fixing your problem by being in denial.

Ok, I've been thinking about this one a lot today. Most of us will agree that you are feeding too much and/or hit them too hard with BM. What I'd like to know is what your roots look like. Any possibility you could slide one out of the pot and snap a pic?

2600watt hps, hortilux bulbs

Looks like light bleaching/burn. Raise the lights and get some cooltubes.

that is NOT bleaching. i run 3000 watts about 14" above my canopy and never an issue.

how about you go fuck yourself sticky and keep your two cents to yourself. ive been running perpetual with a 1.5-2 unit harvest every two weeks for the last 2yrs with few hiccups. six start strains at that, some of which i don't release genetics to even my best friends. one of the first things i learned is the days of The Overgrow forums are long gone, and EVERY opinion must be taken with a GRAIN OF SALT. you brainstorm with people and make your own conclusions, and you're not supposed to get crapped on by some prick who thinks his opinion is word and must be heeded. so, go buzz elsewhere. Nuff' said about that.

Next topic, i think i failed to mention that i recirculate every 3 hours during light period, i also veg them 4 or so weeks so they get about 3-4' tall. during the 4-5 weeks they go through about 150-200ppms daily. i have 8' sealed xxl hoods with a 492 CFM fan bringing air in and pushing it through the hoods. canopy temps are 75-81 with the highest degree being reached during c02 injection for 20min every 2 hours

i thought it could be light bleaching since every strain is different when it comes to acceptable light levels, plus i have never seen these kinda leaves, they literally look bleached. i doubt it though.

so i figured WTF, flushed every "cycle" reservoir and lowered ppm to about 7-8ppms, it's been only 5 days and haven't seen much difference so we will see.

*FACE, i harvest another cycle very soon so we will what the roots look like then, but i'm sure they are fine or i would have noticed something in previous harvest last week (different strain, same methods)
also, i only hit them with the BM cause these went freaking nutz on vertical height, i have been using the stuff for a while with no serious adverse effects. i only use the stuff in emergencies but it is possible that crap fried them since it is volatile stuff.
*CANNA, i recirc and always flush the coco when planting, i use royal gold tuper with perlite, comes damp and drains pretty damn good.

i havent run co2 for the last week so we shall see if that has and effect. i keep u guys updated

i think i might have found the culprit. after i lowered ppm's Ive noticed deficiencies in some of the other grow "phases". strains i have not had issues with before. i had a fungus gnat infestation a few weeks back. hit them with azatrol hydro, killed them and have been running it since. weekly res change and i started reading the booklet label on the bottle and noticed it said a lower dosage then when i first used it. turns out it has several different dosage recommendations. did some research and turns out for my girls i was using 75% more than i should have, and your suppose to use it on and off, not consistently. so i wont run it any more and well see if that changes anything. btw, azatrol is the shizzle for thrips and gnats!
