HELP, Problems During Flowing!!

[GetThisOrDie]

From looking at the pics they look like over fert plus a lack of nitrogen. Like shake asked, whens the last significant nitrogen dose? I might have missed it but didnt see the info on wks into flower and how long they are supposed to take.

I havenʻt given any nitrogen at all, atleast that iʻm aware of. They are at day 21 of flowering. The 2 iʻm having issues with are a purple kush and Romulan, so iʻd have to say around 60 days.

Im gonna flush tonight again with water thats at about 7.3 Ph to hopefully lower everything and help flush emʻ out. i have some Veg nutes that are 3-2-4, should i give them some of that or is there supplement i can use that is only nitrogen ? Also should i give me nitrogen now or since its showing alot of nute burn and just flush like i planned on ??

FP, first off you posted 4 pics in your first post....four pics you had to first upload to photobucket. TWO minutes later you posted the infamous line about how your are gonna try to fill out the troubleshooting form. as a matter of fact you posted FOUR times before anyone else did.

if it takes you 25 minutes to fill out the troubleshooting form then perhaps higher education, let alone gardening is not for you.

if you want to trust your plants to the GUESSES others get from pics then go for it. any respectable memeber around here who can solve your problems are all gonna tell you the same thing "fill out the form". the form is put in place to save both YOU and US time (really three, your plants too). not to mention save us the headache of trying to drag the info out, as is having to be done now. this also allows those of us giving advice the most information we can have to make an ACCURATE, PROPER DIAGNOSIS. again, if you want to trust guesses with you ladies then by all means. not to mention, if people are just throwing answers out how would you know who to trust?

if you bothered reading my post, you would of noticed i gave you advice at the end. what a noble concept right, someone giving advice in the plant problems section. GASP!

if your big ladies are 2 1/2 to 3 feet tall then you are gonna start loosing light at the bottom of your ladies. even with a 1000W HID you only get about 2 1/2 to 3 feet of canopy penetration. those bottom leaves are not getting enough light. the plant is moving the mobile elements to places they can be used and dieing off.

if you don't truly know your runoff pH then why would you flush with water pH'd to 7.3? you are aware this will raise your pH correct? do you have a pH pen?

blood meal is fact acting (using sparingly) and if you get something salt based go with something that contains ammonium nitrate as it is soluble and fast acting.

where exaclty is the plant showing nute burn?

my simple answer is it looks like they are under fertilized (N) and arent getting enough light.

I have some ocean forrest growing alongside sunshine#4, most of the grow being sunshine 4 atm. SO, I am lazy and feed the sunshine4 & ocean forrest at 6.1, and I keep nutes below 1100 before addition of calmag at 5ml/g. My ocean forest girls seem to love it.

considering you are using soil, make some guano tea. use half and half seabird/bat. use this instead of one regular feeding.

If this is all happening to the bottom 1/3 of your plant, my advice (is always) to remove that crap. It never makes nice buds and the plant can use that energy in better ways!

all at your own risk ; )

Itʻs progressed up through the entire plant basically. I gave em 5 ml of 3-2-4 last night and some super thrive I Phʻd that at about 7.3 to hopefully raise the PH of them to about 6.5.

Today while iʻm out iʻm gonna look at some straight blood meal and some guano teas. Iʻm gonna Raise the ladies up about another Ft. and hit it with a mild yet nitrogen rich feeding of either Guano tea, Blood meal or a combination of Guano/sea bird tea.

@ Shake... They were showing nute burn on the lower big fan leaves that looked to have a big lack of N, the tips were burnt and curled up before the problem progressed. The Nute burn looks to be completely gone down, iʻm just gonna try and address the N deficiency and possible lack of light not penetrating the canopy.

@ Copo....... iʻm gonna look into the Guano/Sea bird mix.

Thanks guys, iʻll update accordingly.... hopefully itʻll be gone soon and i can just update my grow log :thumbsup:

that wasn't nute burn at the end of those fans. that a typical sign of the progression of an nitrogen deficiency, as is the problems starting at the bottom and progressing upwards.

if you had nute burn in would show over the ENTIRE plant.

again, light penetration is a partial culprit here.

don't sweat the dead one's at the bottom. like copobo stated, you can always lollipop them. they won't do much anyway on plants that big and the energy (and nutrients) can be used better elsewhere.

that might not be enough nitrogen. just keep an eye on them. you should see changes in the NEW growth first as nitrogen is a mobile element. the old stuff won't repair itself if too damaged. some might green back up.

good growing!

Super thrive is not to be used in flowering

Thanks man!!

I raised emʻ up about 14 inches and now there only about 1ft away from the light. Iʻm gonna keep a very close eye on the new growth with what iʻm doing to supplement the problem. I finally got some bloodmeal but iʻm going to wait and see how they do with the current solution, as well im gonna feed em tonight with 15ml of 3-2-4 (veg formula) and 15ml of 1-4-5(bloom nute) and ph the water to 6.5.

Hopefully this will help emʻ finally turn the naught corner for good. They seem to be slowly getting better, a few large fan leaves are getting worse but overall they seem to be getting better. Iʻll update my Grow log with pictures either tonight or tomorrow morning.

your welcome.

as far as light placement, a good rule of thumb is to put your hand at canopy level. you should be able to hold it there for 5 seconds before you need to move it. light is goverened by the inverse square law (light twice as far away from the source is only 1/4 as strong).

good luck with all the school by the way.
