My runoff p.h. is 5.0you checked runoff e.c. and ph?
Ok I flushed with flushing solution and dropped ec to half I'll let tour all know how they respondMaybe bring down the ec down to half strength and see how they react. That's what I would suggest after a ph balance flush.
Good luck bro.Ok I flushed with flushing solution and dropped ec to half I'll let tour all know how they respond
How long have they been in flower? They don't really grow much in height after the initial stretch starting flower...Nice and healthy I just transplanted 3 weeks ago to bigger pots so I don't think they are rootbound although the ones that are most affected by whatever is going on having rooting into the new mix at all or grown an inch. Which is extremely odd all of them have stunted growth about half the growth I'd expect by now
Ya I know but they barely grew at all every strain usually I get some that do that but not every one maybe a couple inches at most and some none at allHow long have they been in flower? They don't really grow much in height after the initial stretch starting flower...
What I'm seeing looks like it could be lockout from too much calcium, plus the lights being a touch too bright.That's my thoughts was magnesium but I've been using cal mag so I don't understand
Just because you've never heard of it doesn't mean it's not a thing. It's definitely a thing, it's basic chemistry, all elements effect the other elements (nutrients) in different ways depending in a variety of factors. I'm not a chemistry buff, maybe @Aqua Man can explain it better. Here's an article that explains some stuff.Agree Tom. I never heard of a nutrient lock until I joined this forum. I suppose if I dump a bag of fertilizer on plant it will suffer from being grown in the dead sea. Maybe that's what folks are calling nutrient lock. In any case it never made any sense. It's in the same category as flushing.
zill.
Ok awesome thank you I just flushed and halfed the e.c.What I'm seeing looks like it could be lockout from too much calcium, plus the lights being a touch too bright.
Both potassium and magnesium may have been deficient or locked out at some point, and calcium can mess with both of them. There may be some calcium in your water. Assuming that's the case, only use epsom salts for Mg, and don't use cal/mag.
Don't worry about red or purple petioles. They happen when the petioles are exposed to LED lighting.
How is this different than what i said?Not quite - Water flows through cells from low to high salinity as to try to reach equilibrium so as your salinity raises the flow of water slows and it can infact atop a plant from being able to drink and thus stop nutrient uptake all together.
A high salt solution or water being applied to the plant having a high EC will be taken up by the plant. But as evalotranspiration takes place over time the [salt] reaches “ infinity” and the tissues burns, yellows. It’s an osmosis thing. Equilibrium, I’m happy. A hypotonic solution and the cell draws in water. A hypertonic salt solution causes water to leave the plant, cells, roots to try to maintain equilibrium.
Like I’ve said container growing is tough.
Not quite but kinda… evapotranspiration is more for measuring water loss of soil. Transpiration is yes driven by evaporation but is strictly the measurement of water through the plantsorry Aqua, Typo. Evapotranspiration. Actually, evaporation is what drives transpiration.
Transpiration is reducedwhat happens when the stomates close?
