Leaf Spots, weak color, and leaf ripple
bSandersWitASteelChairstarted grow question 4y ago
Please 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?

Hi mate that looks like she needs some cal mag. Be careful when adding cal mag as it contains nitrogen so I'd lower your usual N dosage a little.
Hope this helps 🙂
bSandersWitASteelChairanswered grow question 4y ago
Multiple deficiencies suggested; based on separate research as well I ordered cal mag. Thank you all!

Could be a phosphorus problem starting. I'm not familiar with your nute line up but you may need to start adding a bloom nutes.

Probable phosphorus deficiency?What is happening? It's getting worse. Inert soil, just applying Remo nutrients (all of them). I put a layer of living soil on top, but it doesn't seem to have any effect.PH ok, other plants consume the same water without problems. Very hot here, 35°C/95°F

Leaves turning yellow and dyingI have a plant that gets a lot of rust spots, even though I give it CalMag once a week. That plant also started getting a handful of leaves that turn yellow and fall off. Is there a nutrient I'm missing in my regiment? Should I do CalMag every watering for the rust spots?

Deficiency?I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

I did an LST last time, but I'm not sure I did it right. Can you please tell me, given that the lateral branches are already very active, but the trunshould I do an LST in a 4-5 days? And maybe some tips. Last time I anchored the plant from the bottom so that the roots wouldn't come out of the ground from below and the stem wouldn't bend so much, and then pulled the stem over the top, is this correct?

What should I do with my plants that have grown thicc to receive more light? - First GrowMy plants (1 auto, 1 photo) have grown a lot and are now pretty thicc. Should I remove some leaves to allow more light directly on the new growths from the nodes? More agressive LST? Leave them alone? They have grown in a weird pattern because of my LST attempts (see pic).

Enough LST for an autoflower?I was wondering how much LST and how intense the LST on an auto should be? I heard you shouldn't stress autos too much, that's why I'm extra careful and wanted to ask. (And yes I know it's overwatered, I'm letting it dry out at the moment)

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Early flower and plant too small?Multiple questions: Is this the first sign of flower on the picture of D21 from sprouting? Doesn't the plant look to small for it still? How do I promote new node growth? Is watering roughly about 1.5L per week too little for nutrient influx?

PH-Problems in SoilBefore repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?
