TentGrow 250w MH/HPS NL - Bubble Gum - Brainstorm

It's a deficiency or toxicity of some sort.

Are the most affected leaves dry and crumbly?

Start with little rusty spots, really hard to see if u dont look under the leaf and light is over :) Same time some red leafstems!
Then when escelating the whole leaf is dry and crumbled up!
 
Sounds like over watering to me. I've got the same problem now with my plants after flushing them:(.

Gonna let em dry out over the weekend see if it gets any better! B2 still wet since wednesday :/
Yours look great though!
 
Well a little picture update, not much growing this week, a little bit of trichs! but not much .
Btw is it only me that think smell is lower in bloom? They really stank in veg!

Some pictures after lights off, not beautiful but still alive!

The girls are looking lovely, nice and green. If the damaged leaves make you feel bad just trim them off. You will also then get a better picture of new damage as it happens. Nice pics dude.:thumb:
 
How are the plants coming along? Any better?

Been away all weekend, but came home a few hours ago!

NL looks ok but is really slow budding, a little to green maybe some leafs almost shoni/oily green!
AK48 was big after 3 weeks =),
Brainstorm has the biggest buds but spots has spreading, looks like calcium def.
Bubbles nothing happened at all after 3 days, exactly the same :/ looks like max 14 days in flower....

Thx mr LA, and dutch dragon thx for the tip!

Here is the brainstorm leaf!

I would let the plants do what they're doing. as long as they're drinking, continue to water and feed them very lightly.

Yeah brainstorm, will only get 1liter waterings with small amount of nutes and ph water 6.3!
NL, no more N for now! Goona give her some PK only!

You think i should add some cal to my brainstorm?
 
Day 32

Some pictures of whole the tent!

Gave Brainstorm 2ml Calcium today, and all the other
3.5 ml Canna Terra flores.

Really hope the bubblegums starts producing soon, looks like a really small plant with sativa bud structure.
Plan is to chop em down before christmas IF they are done :/

your leaf damage appears to be a calcium deficiency. I would supplement your nutrient mixture with 5 millilitres per gallon of calcium and magnesium.

Well i guess i did the right thing then :) added 2ml with 1litre of water today and watered Brainstorm, NL will get some when its dried out to!
 
Hmm, what do you mean =)?

Primary (main) Nutrients: nitrogen (N), phosphorus (P), potassium (K)
Secondary (Macro) Nutrients: calcium (Ca), sulphur (S), magnesium (Mg)
Micro Nutrients (Trace Elements): boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni)
