Brown Spots mean calmag deficiency. Just add some and you’ll be alright. Hope it helps, good luck ☺️

Cotyledon issue from seedling
Have seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue? Now I am around 100 PPFD and put the light a bit up. See photo.

Braune Flecken an den Blättern
Hallo zusammen, Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel. Vielen Dank für eure tips!

Dry brittle leaves
Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

Carencia de Mg
Hojas en forma de bandera con manchas amarillas, sin dudas carencia de Mg, el problema es que no se que lo provoca, haré un estudio de acidez al suelo para estar seguro, pero dejo el hilo abierto a cultivadores más experimentados por si me podrían dar una mano con esto

Weed doctors to the rescue
Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

Are those nutrient defficiencies? Which ones?
A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

What’s appening to the little northern light auto?
so far I have only given her the rqs growtablets plus a break of plain water and given this reaction today I have also started to give her some advanced nutrients (MGB) is it just a delayed nutrient problem or should I worry?

Emerging Issues - Week 9
At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F
