my fault. it's autos, outdoors, idk. besides an apparent bug problem of some kind.
First time grower looking for any opinions or advice regarding plants showing signs of nitrogen deficiency AND toxicity. The plant seems to be oscillating between deficiency and toxicity.
First we saw, classic signs of deficiency, the yellowing of bottom leaves started, now there's 5 yellow leaves on just 1 plant. But after I used the General Hydroponics flora series we saw signs of toxicity, very dark green and clawing leaves. I'm worried I mixed the flora series too strong. I can't find the sweet spot for my plants.
I followed a chart made by the company for week 3 of vegetative/growth stage: 5 ml Micro, 5 ml Gro, 2.5 ml Bloom per gallon of water. Mixed correctly and tested and adjusted pH to about 6.4. Also, we've been alternating feedings with plain water and fertilizer solution.
Other info:
growing in a mixture of soil, coco coir, perlite, with clay pebbles on bottom
running lights 24 hours a day
Got the clones a month ago
growing fast, lots of branches and growth nodes, new leaves always look healthy
*one plant is worse than the others and was the first to show symptoms, but others now have yellowing bottom leaves too
The plants are due to be fed tomorrow. I want to try a weaker solution but not sure how to go about it. I could just add water to dilute the recipe above or I could try a different recipe.
Doing more research, I found a different recipe using a ratio method, 3-2-1 for vegetative stage. (3 parts Grow, 2 parts Micro, 1 part Bloom. 1 part = 5 ml) The instructions just say to dilute to your plants needs, up to half for soil. This seems even stronger than what I used.
But then I finally found a 3rd recipe someone is using that is half as strong as the one I used: 2.46 ml micro, 2.46 ml gro, 1.23 ml Bloom.
I'want to try that but I can only measure 5 ml accurately... so, I need to find a smaller measurement vessel.

Hello,
I am growing with GHE products (FLORA series like you have, but also Floranova) for a long time.
The Flora series (Micro, Grow, Bloom) is praised by everyone if you look around, but myself I now need to admit that I ALWAYS have problems with my plants, yellow leaves early on (where there shouldn't be yellow leaves), or in worst case scenario my plants just dying.
Then again I am using three Flora bottles which are (at least!) 4 years old, but I was told by GHE themselves that the stuff should have infinite shelf-life, when sealed and stored cool/dry. (I already opened mine). I have indeed so poor results with growing recently that I absolutely NEED TO switch my nutrients. Maybe the nutrients have really gone bad, I don't have another explanation and I am at a loss. (You have no idea how much I already read into feeding charts, correct dosing etc...and still I always have problems).
Here is the kicker: The exact opposite with Floranova Bloom! (ONLY with Floranova Bloom, up to 2.12 ml per LITER == Lucasformula. [You can google Lucas Formula if you want]. Floranova Grow is not needed). Not only did my plants grow like M*therf*ckers with Floranova, I also never had any sort of deficiency with it. This is another sign that something must be off with my three bottles of Flora. I am about to toss it out.
Otherwise you say 5ml M, 5ml G, 2.5 ml B PER GALLON, which comes out to 1.3ml/L per liter, which to me sounds about right.
Also: You say you are growing in a mix with added perlite, coco...same here! It is possible that this means you need to inc. dosage and especially you need to add CalMag, as Coco is leeching out Calcium. But I do add calmag, but as said s poor results recently I am giving up on the three Flora bottles. I am about to get FloraDuo.
Also: Get these plastic pipettes, you can get these in any grow store, ebay or online. MUST HAVE. Otherwise 20 drops == 1ml. How can you even dose right without these?
Also: You say that descriptions somewhere say "to dilute" for soil. To be more exact, what it says (on the label, and and on some feeding schedule) is that you need to use HALF of what the schedule or the label says for soil. (If it says "Terra: 50%"). Also 2.5ml per GALLON to me looks awfully little to me. Maybe someone else can help there. I wish I could give dosing recommendations, but with my poor results and plants getting YELLOW AGAIN as I type this I just can't. It's incredible frustrating as I am growing for many years already and I am as part of my work even writing on the subject of growing. I feel like an idiot to not be able to grow without major problems, as if it would be my first grow. As said I am at a loss what is going on here, and I have concluded it must be the nutrients.
That stuff (Flora) needs to go in the trash, at least in my case.

the last piece of info i can give: You are not a genius or a godlike deity. dont think you can take a turd in the backyard, wait a week and use that as home made fertilizer (yes, theres a thread on this.) the entire point of this websites' forums is a community of people, knowledge, and experience. trust Roll it up. trust each other and trust yourself.
happy growing!

only guessing the usual, overwatered, lockout, light burn, pH and rootbound. would concentrate on potting up and watering less.
I moved it from the smaller pot to bigger one am using normal soil it was fine till flowering
I already flushed it I tried adding fertilizer only found one that's 6 6 40 npk I was thinking nute lock thing is it's been better lost alot of foliage now it's not loosing anymore everything went to shit after putting matches in the soil cuz I heard it helps with magnesium deficiency couldn't find cal mag or molasses also I tried adding some off
the shelf organic fertilizer idk what to do

I think the 40 is waaay too high potassium. so think flush again. what's your base soil mix? did you add perlite to it?
well I used sea soil
couldn't find potting mix or perlight

it's amazing how many choices there are out there for growing, i don't know what sea soil is but guess if it's soil only you probably want some aeration such as perlite or the water doesn't dry out and therefore it gets over watered. over watering results in over nute lockout as it tries to drink too much. Maybe it was ok until flower becuase the problem compounds but also coincidentally you gave it the 4-4-50 so that made it worse too. sometimes you can wait 2 weeks before watering again. you might try that and also poke right down in the pot with a kabob skewer a dozen times or so. some people say throw the plant out but i think you should try to save it because that is the only way we learn.

Hopefully someone could help me I've had this problem for 2 years and finally worked it out it may seem daft but I've been giving my plants too much nitrogen all the way through veg and upto week 5 flower I'm currently growing highmacs from sunken treasure seeds. My problem is my coco a has 5 nitrogen in it do i still carry on giving it at the recommended dose 2.5ml per l as the chart says on plagron. The worst thing 2 years ago whn I started the charts sadi feed 4ml per l so I've always done that and now I know why I never got yellowing and my flavour just wasn't there but yield and density was good.I also swazzed alot on day 21so put them through it. Does 2 much nitrogen with heavy defoliation stall plants as my buds full of crystal jus look week 4 size not end of 5 thanks and sorry for long post.

I could have wrote that. Same problems with gh, experienced grower, scratches head for 8 grows with trio, same problems in flower every time !!!! It's relaunched "Terra Aquatics" now, just about to try new batch.
Feeling ya pain brother.
