IMHO, I dunno if I would do that. its a single point type light source, I'm guessing just like low power HPS they cause stretching. you want a muted light source to help with tighter nodes, and give you a chance to train your plants. which is why T-5's are so good at this. but even if you had that old kind k3 laying around that would work too.

you just don't want a pin point light sources, you gonna get up on morning and see big long shafts in your face lol.

when I was using my k3 CMH combo, I didn't fire up the CMH's till flower.
Guess I will have to do more research. My first bit of received info on the cmh was they were kick ass veg lights, then people started trying them with flowering and also got good results.

When my kind k5's took a shit I was going to go with 4 cmh. The price then would have been 1900 with tax to cover a 3x12 area although my space is 4x12. Then I stumbled on Amare and for 600$ more got 3 se-450's.

Currently I'm vegging under just the monos at 24" and the plants are showing signs of light stress. These are almost too powerful to veg under. Can't wait to turn on the cob's and see what they do for flowering

If any one thinks they know whats going on with my leaves by looking at pics feel free give me your opinion
I'm 5 weeks into flower as of weds
It's not the Ph
Been adding cal mag and extra phosphorus to feeding as an attempt to correct but not sure if it helped or not . Kind of stressing about it .
For now though buds are still growing and doing their thing
What you notice about LEDs that work well, the plants need a little different ratio of nutrients/ micro and macro. Calmag is the first one to need to be adjusted. And I'd say you have a combo a manganese/cal/mag(balance/lockout/not enough) and p you plant either wants more of or a different ratio.

It could also have to do with the distance you have the light from your canopy and blending with the monos(this would be more if the def is showing on the top part of your plants. You can try raising the light a bit if possible or tying down your tops.

@Billygreen are you soil or hydro?

Cut out the calmag for a couple feedings. Replace it wIth a ~4:1-5:1 of RO:tap water and see if that solves the problem. Too much calcium to me from the pictures.

ill eat some words here, and back up. I think CMH's in veg is excellent, but only after you're done topping and training. is what I wanted suggest. for me I try and keep'em short as I can, bend, top, get under the fist trellis before the stems stiffen up. then move then to the CMH. just like you would any normal staged system.

No need to eat any words. I love advice especially from knowledgable people. My plan was while 0-3" tall I would use the fluorescents only. 2 54watt t5ho then when they grow a bit bigger add in the cmh. Then when vegging is done go to the Amares. I was thinking cmh because it's a fairly intense light and while raised would cover my space well. There should be less shock going from cmh-cobs than t5-cobs.

Last night just gave plants straight water figured id try flush them out a bit
It could be too much calcium , I have used tap water since the beginning and may have misdiagnosed a previous issue as a cal mag deficiency and ended up screwing shit up . One of my biggest plants with a shit load of bud sites is doing the worst ..All the upper and mid leaves are getting all spotted up and drying out ...At this point I don't know if its going to last 4-5 more weeks . Any way its pretty fucking stressful being new at this and getting so close and then shit getting messed up

And another frustrating thing is that alot of symptoms are similar for different issues or deficiencies..Being my first grow I realized I don't know shit really even though I've immersed myself in all I can about growing ..I know it takes time and experience to get good but when I have over 20,000$ invested in this I don't have the option to fuck up 4 months of work and time

Growing in coco mostly and was experimenting with couple water farms
Those are only 2 plants not suffering from whatever the others are

There's a pic of what i was going off of for feeding and also use Bud kandy and Rock
And was using cal mag regularly starting early in.veg and plants couldn't seem to get enough ... I vegged them for around 6 weeks and then about 2 weeks ago started seeing the spots and then it got progressively worse .
The really bad looking leaf pic is of one that was near the top of plant under kind light .

I want to buy one just to see how they exactly built it. These look like awesome lights and would kill it with higher temperature cobs for small veg rooms I bet. I just hung a 315 lec in the center of my room and 2 wall mounted t5's for a little extra blue. I bet 2-4 of these on the sides of the lec would be sick.

With my new Amares and the lec I'm not in need of much light but i want all this new shit too lol. Even though I got hosed by kind I would love to add in some of there new light bars between my se-450's too. I really think there is a market for lights like these posted above and light bars. Maybe Victor will read this and start doing bars and 6500k cobs.
im going little craizy , its those 4 lights or 2x180w hans panels, or photon 6.. hans is most expencive,then it goes tg star60, and last is photon 6.. i like hans most coz drivers are separated and i can keep them out of tent and that is excelent because of 30+c summer temps.. And yes this is what 2x85w hans does,in 80x80cm space.. and i m looki g at 2x180w to buy..gets you thinking..

looks like classic overtfertilization to me billy... im not seeing clawing really... and cannabis in general is pretty tolerant of high Ca levels. My feeling is you are over using boosters.Although im not sure what your regimine is.

You could saves little money and go with these. Even a easy YouTube video on how to put it together

I definitely don't know what the problem is and you might not want to hear this anyways but this is part of the reason why I started with and will continue to do autos. Spend months learning and think you know everything when there's really no way to learn without experience. 55 to 65 days strains still produce upwards to 1/2 pounds per plant and if there's a problem you will most likely have a new batch coming up shortly behind.

Main reason why I came to the forums was because of problems like this. It's like all these growers that I'm friends with were so willing to give in the beginning but when I got in deep no one was around. And there's that old saying don't count your chickens so they're hatched fits in with mj growing so well. It's a bitch billy and I hope it works out for you.

Thanks man, and yeah thats true ..I thought I would be able to get some guidance from a couple people I thought I knew but seems they know less than I do and thats not saying much . These guys were experts until you start asking real questions ..

So I'm winging it and trying learn what I can online and picking through the forums separating facts from bullshit which there is an abundance of .
And yeah I am giving the Autos a shot. Dropped 16 seeds last week and they all sprouted so crossing my fingers they turn out well and maybe ill switch over to just autos if they can produce enough. I picked supposedly high yield varieties..

I haven't given up on my current crop but its just painful to see your hard work suffer ..So at this point I'm doing what I can and hoping for the best . I have taken some corrective measures but results take a while to become obvious so it's a waiting game as I watch for improvement or further deterioration.

You said you had issues with your first crop ...How bad did it get ? Did you have issues with deficiencies during flower and if so what were they and how did you fix it ?

I've got 5 weeks left so it could go either way I suppose

I had burnt tips and yellow leaves. Cal mag deficiencies and changed my lights 5 times during their lives. First auto grow I pulled 2-4 oz a plant which blows but I would have figured much less. At the start of flower I had people swear they were 3 month vegged photos they were so big but they took a shit at flower.

You guys can download the "Grow Bible" for free. Good starting point for anyone .

Calcium is a delicate dance, I'm assuming you washed your coco, but if you are supping with any calmag on top of your normal regime- Im putting my cards in excess calcium binding up locking out P, Mg, and of course Ca (which is the "def" I'm seeing with your rust spots) Looks exactly like my finicky ass Tangerine Dream, as soon as I cut the calmag for my RO and started mixing my tap water in 5:1 (90-100ppm mixed) they thanked me.

Good luck
