Hey grüß dich. Dadurch das es bei den unteren Blättern anfängt, sieht es aus wie ein kleiner Magnesiummangel. Kontrolliere den ph-Wert im Boden. In der Vegetation sollte der ph-Wert bei 6.4-6.5 und wenn es zur Blüte geht sollte der ph-Wert zwischen 6.8-7.0 liegen. Die Pflanze ist bei unkorrektem ph-Wert nicht in der Lage die Nährstoffe so aufzunehmen wie sie es benötigt. Es kann durch einen unkorrekten ph-Wert eine Mangeerscheinung auftreten obwohl genug Nährstoffe vorhanden sind. Ist der ph-Wert im Boden bei ca 6.5 ist es ein kleiner Magenesiummangel und es muss nur etwas calmag zugeführt werden. Einen Mangel erkennt man gut daran das meist die unteren Blätter betroffen sind.

I seem to have some yellowing on fresh growth starting to occur. I'm not too sure how to prevent it. I have started to do some LST and find it to be successful and a lot of fresh sites have appeared and wonder if this could inhibit it by stressing the plant?

Hi, 3 plants look really healthy and they grow as expected. However one LSD-25 plant seems really weird. I gave nutriens just twice, other waterings were done using tap water with controlled pH. Could it be connected to hight temperature or is there maybe a problem with genetics?

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!

Day 67: after watering, I am noticing the leaves curling under, but fine next morning - or at least less clawing. Does this look like over watering? Watering every other day 1/gal per 7gal fabric pot with 2/3 soil, 1/3 perlite well mixed. If not, what might cause the claws?

Seeing the leaf tips clawing a bit. Plant looks healthy, no dark green (too much N). Having full wet / dry cycles. Not adding any nutes so wondering if it’s a sign of a deficiency of some form. Been like this for about a week and no other obvious negative signs. Thanks!

Hello guys, This is my first grow and I need help. Leaves started curling downwards. I'm not sure whether it was overwatering, underwatering, or needed repotting to a bigger pot. I repotted it today to a bigger pot and crossed my fingers. If you know what's up please help! Thanks

Any ideas for why this girl is starting to claw. I was thinking it was nitrogen toxicity but doesn’t make much sense as I just changed to flower Nutes. Ph is good and ppm was around 700.maybe overwater.

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy. Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator. It seems to be curling in as well.
