Problem child day 40

[canocrpse86]

Hey guys

Was suggested I come over here and ask for some extra opinions. We haven't been able to come up with the solution in my journal and somebody told me @Waira is a plant wizard.

Background. This girl has been my problem child since day one. Her sister has been an angel.
Plant is lanky and anemic looking. Pale leaves with almost zebra stripes on them. She had curling leaf tips and looked like N tox at first. I flushed her and cut her base nutes down a bit. Now she has leaf tips looking burned, pale leaves, what looks like Cal or Mag deficiency on lower leaves. Looking at the pale stripes and burnt looking tips I thought maybe zinc? Flushed again and Adjusted ph down lower from 5.8 to 5.5. That didn't have any effect either, or at least didn't seem to. One thing I can say is she's still growing taller at a fast pace.

Currently feed is per gallon
2.5 CalMag
2.5 h&g cocos base 2 part
.5 SiArmor
1.25 roots excelurator
1.25 Algen extract
1.25 amino treatment

Basically the house and garden lineup with added calmag and silica.
Ph is 5.8 and ppm is approximately 600

Let me know if you guys have any suggestions for my red headed stepchild.

What type of light? Is it LED? And if so are they 5W diodes?

Yeah they are 5w diodes. It's a Mars 900w. I don't think it's light bleaching from the LED though because it's all over the plant, not just at the top. I'm assuming that's where you would see issues?

Mine looked just like that from lumen toxicity. doesn't mean it's your problem but it looks just like something similar that have an of my plants you can go back over to my girl journal and see. but I was getting a false positive that my plants were wet because humidity issue too so they're gonna be numerous things playing in to that. I have to keep these lights I have had about 30 inches during vegetation

And I'm not just talking about bleaching. lumen toxicity appears as calmag issue because the 5w diodes really suck the Cal mag out of the plant.

I also need to say that I am nowhere near experienced as some of the other guys here. But I'm sure @Waira will drop by soon.

Hopefully we can get someone better than me to help you out. Definitely looking like a lockout issue, not sure what. @Ripper or @budelee @Bailey can one of you help

Good morning, i would offer any help i could,just throwing this out,and it prolly has nothing to do with the issue,the feed at 600 seems a bit low,but i get what ur saying about it looking like N tox..im not an LED grower,i will however,follow along to see what the outcome is...peace

Hey bro thanks for the tag @Dudeski.
She is mag def imo I would purchase Epsom salts and feed her that way as led's make plants hungry ill also tag @Elvis who in my opinion is another plant wizard

Ok so the led issue. I know this is kind of a heavy panel for a 3x3, but I don't move the light at all. It stays all the way up at the top of the tent. At this point the plants have probably grown to within 30 inches of the light at like day 41 but I don't think they will stretch much more. Does the lumen toxicity come from it being too close? Or just the plant being sensitive to too much light? They are also on 18/6 schedule.

Mag issue. This was along the lines of what I thought. I have been feeding 2.5 ml of calmag every other day since the beginning of the grow. My supplement/calimagic also contains some N so I have to be careful how much I am adding. Do you think I should just bump up the ppm all the way around?

As far as lockout is concerned. The plant is in 100% coco and I have flushed it 3-4 times with no improvement. The only thing I can think of is PH issues with my medium possibly locking something out. Don't know that I can change that though.
