Nebula def please help

[Nifty_PoT]

Well hi guys
This is what i have a sick looking nebula .. I gave equal amouts of Grow and Micro and a bit less bloom untill ppm 540 was reached. Ph is at 5.8-5.9 . I really dont know what this could be some said its a Ca def so i foliar fed her yesterday and today with some dolomite lime @ 1 teaspoon to a liter. This morning i saw leaf edges going brown and the tips.. pleaspleas help
This is the Arctic Sun she has more of a Mg def i think she does not show any of the brown spots as on the nebula..

nebula.

Strain of Mj?
Hydroponic or soil?
From seed or clone?
Age of plant in question?
What stage (Veg/Flower; how many days into)?
Medium (Soil, Rockwool, Hydroton etc.)?
Container/Pot size?
Have they been transplanted, if so how long ago?
If soil, composition ratios (peat moss, perilite, vermiculite etc.)?
Water runoff Ph?
Nutrients added?
Ratios of nutrients (N% P% K%)?
Feeding schedule?
When were they last fed/watered?
How are you determining when to feed/water (weight, wilting, etc.)?
TDS/EC/PPM?
Tap/RO/Distilled water?
Ph before and after adding nutrients?
Is your Ph equipment properly calibrated?
Light intensity/Age of bulb/Wattage?
Distance to the canopy?
Temps at canopy?
Temps at root zone or reservoir?
Day/Night temps (Min.-Max.)?
Current air flow (CFM)?
Is there air blowing directly onto plant?
Using CO2?
Relative humidity?
Growing technique (Scrog, Sog, Supercropping etc.)?
Has plant recently been pruned, clones taken, fimmed or pinched?
Pests?
Chemicals used to irradicate?
If so,When?

looks alot like some salts are building up.. i dunno tho.

Hi teddybud I changed the water of the system about a week ago when i saw the signs of possible mg and Ca deficiency's, and i cleaned it pretty good so i dout if it would be salt buildup?

 

[Nifty_PoT]

someone please? i have no idea what to do!!

 

[Brian1975]

What was the PH of the foliar spray at that concentration?? You could use more epsom in your concentration. I use half a tsp to a full tsp in ONE gallon of water when I apply it.

 

[Nifty_PoT]

ph of foliar sparay is 7.3 . Wouldnt adding that much epsom salts raise the ppm too much? I mean i just add 1 teaspoon and ppm goes up with like 40

 

[Brian1975]

I don't grow hydro so I don't know about all the PPM's for this and that. I do know that a PH of 7.3 isn't something I would be spraying with. Could be what made it worse. As far as the initial problem, I am not familiar with any nutes but my own. I know that mine contain Magnesium and I supplement a few times during the grow with epsom.
Do you use a calcium supplement?

 

[Nifty_PoT]

Nope i use nothing but the gh 3 part and ph down lol and 2 teaspoons epsom salts

 

[Blackvelvet]

Stop trying to spray dolomite lime. LOL.

Try 1/2 strength 15 ml grow + 10 ml micro + 5 ml bloom per gallon (3.8L) of water. For 100 liter rez, 197 ml grow, 132 ml micro, 66 ml bloom. This is basically 1/2 strength Hoagland nutrient formula. Google that. You may increase strength to 2/3 x once plants get slightly larger. Keep that ratio of grow to micro to bloom.

GH 15grow, 10micro, 5bloom
211 n
46 p
263 k
40 mg

I think I might bump my mg from 20 (1/2 x 40 =20) to 25 ppm mg. Not much difference really. If you got 100 liters, you would add about 9/10 teaspoon epsom salts. 1/4 teaspoon epsom per gallon (3.8L) = 30 ppm mg

BV, Just curious... Do you grow?

Read the links in my sig Nifty Pot... not the seed links, the other ones...

 

[Brian1975]

All of those figures fry my brain. Oh, didn't you know??? Come on BV, show us that jungle you call a garden. Guy has like 80 strains going with numbers and ratios flying everywhere. Plants the size of redwoods grown using his highly intelligent, overly-calculated and incredibly interesting growing techniques. His first love however is growing mushrooms. When you are in possession of as much bullshit as he is....it only make sense.

 

[Blackvelvet]

BV, Just curious... Do you grow?

Why? You gonna send me some seeds?

 

[Grat3fulh3ad]

Nope... Your advice usually seems like it is coming from someone who has a bit of theoretical book learning but doesn't grow cannabis... If you'd like to start, I'll send you some seeds though...

 

[Grat3fulh3ad]

Kind of reminds me of a guy who was gonna give everyone miracle yields with borax and battery acid...

 

[Brian1975]

I want some seeds too!!!! He will analyze them to death if you give them to him. He will get out his grow destroying, percentage spewing, nonsense supercomputer and kill them! Do you really want that Grateful? Could you live with yourself?
