IMO- black mold will start at the base of the leaf.
When they get cold the tips of the leaves will start turning black/purple.
Your plant looks decent except for the black at the center.
No one can tell you when your membrane should be replaced; it's only a guess. Test to determine when to change a membrane. When the TDS creeps up to 30-50% of the TDS of the raw water, replace the membrane. Changing the sediment filters helps protect the life of your R/O membrane
RO/DI water? then add cal/Mag
Nutrient solution temp is okay?
pH is okay?
You should be able to follow the feeding schedule.
IMO- I would go 1/2 strength on your nutrients.
check your pH. I would start there. if it's out of range fix it, if it's in range then you might be looking at...
You have some leaves in the middle that look like a pH problem.
Bottom growth looks way to green.
Leaves are clawing, like was said (N) toxic.
Leaf edges are curling up, I can see on...
Yes. slowly in flower as she become more mature she will die.
Yes you could clone the auto-flower, but your not going to gain anything from doing it.
IMO- your further off not cloning it. let her do her thing.
Good Luck on your grow
the hash on the outside of the ball will lose a little potency over time. not to much
"Marijuana Chemistry" has a good section on hash and storing it.
IMO- I wouldn't do the bees wax truck your thinking of.
Just keep the air, and light away from it, and hot temps.
Yah the red colored tube is your waste water, the blue tube is your good water.
That's if you have colored tubes.
You want to run the proper water psi.
There is instruction on-line, google your system.
what your seeing the stretch is root growth.
everything under the cotyledons is root, everything above them is Shoot growth.
It's normal, the name of the game is to get above all the other competing plants.
IMO- if you want to keep your sprouts short you need loose material for them to root in...
IMO- I think they got stressed from the transplanting.
I've used M3 soil before it's good stuff. just add water.
They look over watered, but stressed plant will look like that also.
Your soil isn't to wet right?
Humidity is a little low, but that shouldn't be do much of a problem.
Did you have...
Roots before Shoot. :leaf:
Give the plant time to grow a root system.
don't water to much, just moist soil never wet.
Little sprouts don't need much water any way.
Good Luck on Your Grow.
WW -Indica 60% Sativa 40% but that all varies to some degree, they try to breed it out, but that phenotype (Growing Tall) surfaces now and then.
Geno-type. Right in the heredity of the plant.
IMO- get some "Bush Master" Humbolt makes it. it stops your plant from stretching alot.
You don't need...
