Plants need help, not sure what though

[CaliVeganix]

Hello Icmag, I've lurked on the forums for the past two years but never really had to post as I had a mentor in the beginning. Fast foward 3 years later and now I'm on my own trying a different lighting arrangement and nutrient lineup and having some issues (or maybe just paranoia lol). Im having slight chlorosis on the top leaves in the center of my canopy and the buds coming in seem more yellow then green, the crazy thing is there's no visual burning or cupping on the leaves near the budsites. Which makes me wonder if its nute related (npk ends up calculating to 1-3.5-3 for what it's worth). The room is 15'lx13'w. I'm running 72 plants in 3 gallons of ffof soil, in square pots, on (3) 4'x8' flood tables (96 sq ft). They are approximately 2 ft off the ground and under (8) air-cooled 1000w Dominator XXL hoods dimmed down to 6400w (it seemed as if I got light bleaching on the growth tips when turned up to full power). There are 4 oscillating fans mounted to each corner of the room to ensure proper airflow, Exhaust fans ducted to each pair of lights for a total of 2,880 CFM. Daytime Temp 76-78, Nighttime Temp 65. Drain to Waste. Tap Water. Tap Water comes out at 6.8 and the temp is 76. Watered when soil dry, Nutes Ph'd to 5.0. PH runoff was between 6.3-6.8, now this last feed I Ph'd to 4.3 and the runoff came out to 6.0-6.2. The strains are Skywalker Og, Oregon Kid Banana, Triangle Kush, Gorilla Glue #4, and Private Reserve Og. Vegged for 2 weeks fluroscent, 3 weeks veg 4800w hps being "mainlined" and "topped" two weeks prior to flip. Suppercropped, Lollipoped day 10 of flower. Their on day 18 of flower. Light from Canopy distance between 18"-22". Using Bio Canna Flora, Boost, and supplementing phosphorus and nitrogen with natures nectar. Heard their nutes are a bit weak on other threads so I fed heavy and it helped SOMEWHAT with the pale leaf color but not the color of the buds coming in. Aside from the possibility im missing micros, im thinking my slight rise in PH or light bleaching is the culprit. A buddy told me that happens with explosive growth and the plant will eventually catch up. Wish that were the case but it sounds like wishful thinking. Was thinking of adding co2 until 1200 ppms might help with over light saturation, But I'm not sure if that's even the problem and was hoping one of the senior members could help out (or ease my paranoia). Now that i've provided as much detail as I can think of..... someone PLEASE help. Thanks everyone.

Post a pic and you'll get answer ....^^ Reading that lot with no pics ain't worth bothering

barely got a chance to get these up

here's some more

here's some more

The ones above ^^^ are following the plant from clone to first week after flip...the ones attached to this reply are showing the canopy right before the flip, a week after the flip, the training they went through (lollipop,supercrop) and the top of the canopy as of two days ago, that way you guys have an overview of everything up to date. I'll get a close up tonite of the yellow-green bud sites in question.

from what I can see, they look ok.
just remember to keep your ph adjusted right from 6.3 to 6.6 for soil.
if the yellowing gets worse on the top you could give them some cal/mag with iron in it.








peace!

Mystic Skunk. Thanks brotha, definitely makes me feel a bit better. Ive included a bit of gh cal-mag with each feed but it doesn't say any iron on the bottle so I'll probably get some kind of micro with iron in it, thanks. I'm also hoping to have corrected the PH issue so hopefully it's smooth sailing from here on out. I had some bleaching on the tops when turned up to full 8000w and turned em down to 6400w last week and am wondering if in the time since I've turned em down they've recovered and are growing fine. Care to weigh in? I've included some up close pics of the buds coming in. You can see in one pic the VERY tips of the bud are bleached, will they still grow out fine since I caught it early or am I looking at significant loss in yield? (Secondary shoots seem not to be bleached) Thanks again

Looks like you need more light

 

[CaliVeganix]

If your serious, pics are taken with lights off in a bathroom so the color of the hps lamps doesnt throw off the colors in the picture (allows for a more thorough diagnosis). 8 lights over 3 tables is bright! That being said I'm pretty sure your being sarcastic as you can see white tips from bleaching in the pics (nevermind the 8000w hortilux bulbs over 96 sq ft, which is 12,000 lumens per sq ft). If you are being sarcastic, you might as well not comment since you really don't have anything productful to contribute (it's obvious my plants reached light saturation) don't need sarcasm to point that out. Just wondering if since I've turned em down a bit if the tiny bleached tips will affect yield now that normal growth has resumed?...or if you can keep up...would increasing c02 to 1200 ppms (which opens the stoma more, therby inrcreasing photosynthesis, and allowing the plant to use more light) allow me to use all that light or would 12,000 lumens per sq ft. still be too much and still lead to me reaching the light saturation point? Hence why I asked for a senior member to chime in... If your not running hps' amd multiple overlapping lights you really wont know what i mean i say im trying to maximize lighting without reaching light saturation or the point of diminishing returns...fwiw, NEVER had issues with this setup because I was running older bulbs from my last setup the year before...now that they are brand new it's....affecting things

Don't use cal/mag every time you water if you are. It may cause a K lockout.

A few rusty nails thrown in your water bucket will give you some cheap iron.

Every week, I add one nice drop of mollasses to my water. It's rich in iron, potassium and all kinds of goodies.

 

[CaliVeganix]

And again, if you were serious, apologies for coming off rude...lots of characters on these forums...so if you are serious, what light intensity would you recommend? I know plants don't register lumens (it's PAR levels) but I still thought 12,000 lumens per sq ft would suffice

 

[CaliVeganix]

THANK YOU Corky and Mystic Skunk I really appreciate the serious replys. Was scared of that happening but didnt really know what locks out what.. thanks bro will definitely use cal mag sparingly (once a week probably)

 

[CaliVeganix]

And mollases has Iron....AWESOME and CHEAP lol thanks

And mollases has Iron....AWESOME and CHEAP lol thanks

Be careful don't use too much.

Watch this.

if your plants are starting to burn when the lights are turned up I would keep them on the lower setting for now to see how they like it.
from what I can see they don't look like they are starving for light, they look good! they are just getting a little yellow.
do what corky says with the nails and molasses or you can get some botanicare cal/mag it has iron in it.






good luck!

Thanks you guys I appreciate all the feedback. Good to know there's still hope for a good yield in this slight bleaching situation. Will definitely keep the lights down a bit, get on supplementing with some micros, and watch em bounce back I will report back in a week with an update in case anyone looking at this thread wants to see how it all turned out. Much love

You have plenty of light. Running that much you should already know that if the wink wasnt enough. It was a joke bud, lighten up. (Thats a pun, im not suggesting to add more)

Hope the issue gets fixed and ya rock the eff outta flower dude.
