yellowing with brown spots and leaf curl, HELP!!!

[mr.niceguy]

alright im about 3-4 wks into budding. this startd about 3-4 days ago and is quickly getting worse, ph is 6.2 and i just got done feeding 2 days ago with 600 ppm of pbp bloom, liquid karma, and blackstrap molasses. i think it might be a calcium/ magnesium issue, no? any help is greatly appreciate it.

yea

yea

damn man i have the same problem i was thinking it was a high ph but what do i know

 

[mr.niceguy]

it couldnt b ph kuz mines at 6.2 which n soil is optimum atleast thats wut they tell me...it seems like it is a calcium/ magnesium issue cuppled with phosporus maybe?

thats a classic case of fert burn my man. I have done that a buncha times lol

flush those ladies and all will be well in 4 or 5 days. cut off the dead leaves they will be fine.

no offense chain, but that doesn't look like a 'classic case of fert burn'.. fert burn the leaves should be healthy green for the most part, with only millimeters of the tip of each leaf burnt/crispy..

that, IMHO, IS and classic case of underfeeding..

the plant(s) need Nitrogen and micros.. 600 ppm is not nearly enough IMHO for those plants.. I would try to get the ppm to about 800, and then up it about 50-100 ppm until the bottom leaves stop yellowing/curling/spotting..

You have everything you need in terms of nutrients, you just aren't using enough..

good luck..

no offense taken at all, just i have burned a couple diffrient strains before and they all looked like that. to me leaves curling up is a sign of fert burn . also look it up in the medical growers bible the pics of fert burn look just like that.
just trying to help a little. maybe you could flush them and see if they get better in a few days, if not feed them... I think it would be easier to do that than feed them now and burn them worse.
At the begining of over fet they are still green but if you really cook them they will yellow and brown and fall off. again just trying to help , im not an expert or anything.

Gunna have to agree with chaingmai on this one. Unfortunately, I've fried plants before as well & the fan leaves look just like the pics above.

yeah, u can get a plant to look like that with constant overfeeding, over and over again.. but taking into account that he's feeding only 600 ppm, that's pretty much impossible imho..

Usualy, when i've had a plant burn, or given the plants way too much nutes.. one of 2 things happen.. if it's just a lil too much i get minor tip burn.. if it's way too much nutes, the plant just wilts and will die if not flushed..


sure, it could be a case of constantly overfeeding over and over.. but at 600ppm that's highly unlikely..

I'm not saying it can't happen, but it's far from a 'classic' sign on fert burn.. I say that because nutrient deficiences can do the EXACT same thing..

taking into account the level of nutes he's feeding at, burn is highly unlikely..

I feed most plants 700+ ppm on every watering under floro lights and still can get the odd deficiency. under HID i feed at least an average of 1000ppm on every watering, again, never burning, and still can see the odd form of deficiency..

And i use chems, he's using mostly organic, which is much harder to burn with..


technically, not taking into account what he posted, sure, it could be from burn.. but we have more than just pictures to go off..

ok tnx for the advise every1 but i think im gonna go with bean on this one, it wuznt until i gave a good flushin that they startd showin doin this with the leaves so i assume i flushd out some of the nutes that she needed. so i think i will take ur advise bean and give another feeding of 200ppm of cal/mag 2morrow.

with overfeeding, ive nvr overfed anything, bettr 2 lil than 2 much and i go by that philosophy. but from wut ive learnd a plant will not yellow when nute burned it will just get crispy, if ull notice the leaves r yellowin, (possibly calcium) and then brown spots r developing (possibly magnesium) and then the whole leaf will curl upwards (possibly phosporous) tnx again every1

I'm with beancounter on this one...looks like multiple nute defs (N, P & possibly others) IMO as well as PH problems (from the spotting on the leaves). Up the strength on the nutes and watch the PH going in and the runoff.

What's your water source, PH & PPM?

 

[Brother_Monk]

Yeah, ditto. I'll back up BC as well. 600 ppm with organic ferts is way too low to burn. Also...your leaves are curling up around the edges, what's your Relative Humidity at?

[mr.niceguy]

tnx guys

tnx guys

sandman - im with tap water, ph'd 2 6.0-6.2 and my ppm without any additives is 48-50

brother monk - i wuz struggling with the humiditiy wuz at around 40 on a good day with lites on, im ashamed 2 say that it hit n the low 60s with them off. BUT now it seems i have that problem resolved withlites on around 30 and with lites off 38

wut do yall suggest my ppm should be at? and also should i mix up another batch of pbp bloom, liquid karma, and add cal/mag 2 this mix? or should i just feed with the cal/mag?

 

[Guest]

Your ppm should be around 800-1000. Mix up another batch of nutes with the cal mag and bring ppm's to 800 and slowly bring ppm's up every feeding till you hit a 1000 or 1200.

 

[mr.niceguy]

well i got a 450 ppm batch of just cal/mag 2 feed with 2day.

 

[mr.niceguy]

bump

Your ppm should be around 800-1000. Mix up another batch of nutes with the cal mag and bring ppm's to 800 and slowly bring ppm's up every feeding till you hit a 1000 or 1200.

what's the bump for? That was extremely good advice!
