Calcium deficiency?
GreenCosmos
started grow question 3y ago
Saw this little brown/yellow parts today. She is in BioBizz LightMix Soil and gets 0.3ml/L BioBizz CalMag 3x per week. pH is above 6.5 . Today I gave her 1ml/L CalMag. Was this the right choice? Is this a calcium deficiency?

This is calcium deficiency and likely due to ph getting too high. Likely need to increase feed amounts

I'm not sure if it's calcium because it forms from the edges and makes lines, which seems more like PHFluctuations

Deficiency or ending cycle?
Hey! I was hoping someone could tell me if the first plant has a deficiency you would recommend I correct or if she is slowly coming to an end of her life cycle and I should just let her fade? The last picture is my other plant, less severe, but same question :) Thanks!

What causes hydro Ph fluctuations early in the grow?
What causes dramatic ph fluctuations in hydro conditions so early in the grow, and how can I mitigate it? I have hard water, so I know that’s part of the issue (I tried to install a RO system recently and failed miserably). Other than frequent testing & additives, what can I do?

leafs with brown spots and olders become yellow and curled
I'm trying to figure out what is the problem with the growing of my plant. The upper leafs are quite normal, even if they tend to bend downwards. The old leafs start with brown spots and then they become yellow and curled on the peaks. Please help me to understand what's going on

Ppm in runoff higher than feeding
The run off ppm is around 500 and when I watered it it was around 200 ppm. Ph levels are fine. Does this mean it’s not getting the nutrients it needs? How can I solve this?

Why is my WW seedling browning?
I have a White Widow seedling that is showing brown spots. I am not sure if the LED light was too close, or if it is showing nutrient deficiencies/excesses. pH=5.8, PPM=160 (80ppm in well water).

Possible pH issue.
(15th photo) I've a few leaves which are not looking the best. Does this look like a pH problem or does anybody have other info? I have dropped a bit of lemon into this plant which is the only one with this issue which has not touched the other 2 plants under the same regime. Tx
