Browning of leaves
CRiSPrGrowanswered grow question 5y ago
hi there Habosabin, that's micronutrient deficiency, you're adding silica which is basically optional but you're forgetting calmag which is absolutely necessary in soiless grows. Just add calmag asap . Hope this helps ! 🚀

Hi there.I’m almost sure it’s a female (pic). I got my first bugs. By the look of it I guess it’s spider mites. What I did so far is spray top and bottom leafs with a neen oil solution after lights out and since I saw it on only 2 of the bottom leafs (removed). Any other tip?Week 12

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Just to confirm, this looks like nute burn, doesn't it?Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)5y ago

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?Week 3

Nutrient DeficiencyIs this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.Week 5

Leaf Spots, weak color, and leaf ripplePlease help me identify possible causes of this: small spots on leaves, minor color fade (not burn) along edges, and strange 'ripple' effect.
A user commented that he thought my plants looked deficient but hasn't elaborated further yet.
What might this be? Multiple issues?5y ago

Leaf yellow dots, small holes and dry/degraded leafHello guys. although some of the guys here said that my plant looks healthy (I just posted some pictures in another question and in my diary), I'm really wondering about some leaf (lower ones). I also found some "tiny" hole, you can check one in a picture. It's all right?Week 4

Is this Yellow spot septoria?Hi gromies. Is this yellowing caused by septoria? Or just normal N deficiency during flower. I can see minor pest remains ob leaves and stuff but not affecting plant overall. Plant in good air flow and humidity around 50% so I question whether it's septoria. thx in adv.Week 11

Manchas en hojaHola!
Aparecieron estas manchas en una hoja de una GG#4 de zamnesia en su quienta semana vegetativa.
No es algo que me preocupe, ya que la planta tiene una apariencia sana y crece vigorosa. Pero nunca vi este tipo de manchas y me gustaría saber su posibles motivos.
Un saludo!Leaves. Color - Yellow
