Hi everyone just need to make sure it's mag def growing in biobizz lightmix using grow and bloom and calmag from biobizz phed to 6.3 currently on 1ml grow and 0.5ml bloom and 0.5ml calmag temperature is steady at 23 to 24c humidity is 40-45 using ts1000 marshydro I've tried to give her calmag today at 1.2ml/l only water or does anyone knows the usage of the calmag she is 32 days from seed 3bog any help would be grateful

Yes the appearance is a Mg problem but more likely it is from too much Ca or K.

Go read this and see if you can figure out where you went wrong.

Here's a question for you...does this chart also indicate the possibility of a chain reaction? i.e. the plants look over-nitrogenated, which locks out K, so then there's excess K in the medium because it's not being taken up, therefore Mg lockout? Or is that assuming too many causal connections?

Hi that could be aswel but only using 1ml/l grow and started using bloom at 0.5ml and calmag from biobizz at 0.5ml will try to use maybe just grow and bloom to see if it improves I'll try next watering 2mo at 0.5ml grow and bloom

Are you following a feeding schedule created by the manufacturer or a well-known grower? Or are you just winging it?

 

[Smokingjallday]

No not really just usually starting with grow after two weeks and increase the dosage if the plant is looking for more and start with the bloom after stretch stops at 0.5ml and increase every week then have soft tap water 38ppm so thought the calmag would help but some of the leaves are dark nitrogen too much alrite so that's probably as u said locking out k and mg then I ph everything now because usually have low ph after mixing grow at 5.1 so using biobizz plus ph aswel at 6.2 to 6.3 the second plant is starting to show same symptoms

Maybe i should do feed/water/feed aswel
