What's the problem?

GrowP4Ystarted grow question a year ago

Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.

Solved

Leaves. Twisted

Leaves. Color - Yellow

Are all strains showing same symptoms? Is it nearer tops or bottoms? Definitely got tip burn. The stains I can't see but if they are like purple hues then don't worry it's because of the low 20°s. Plants show more when a bit colder. If stains are more like a white residue then that could be from moisture from condensation where leaves touch or overlap. A bit of defoliation and a fan will help that. Not addressing that could result in mildew or bud rot. As said already pests could be an issue. Inspect closely. This should be done anyway. So should keeping a journal of feed strength and pH level. All parameters really. This is the only way or the best way of solving issues fast. Hope this helps.

Thank you very much for all your replies, I will definitely keep a diary for the next one. The other plants have the same symptoms but less visible and it starts at the top. It's my first time and I've made a lot of mistakes, I'll take all your comments into account. Thanks again for your help.

Close to taco leaf aka heat stress, but ... That wrinkle reminds me more of plant having root issues. Either overwatering or something deeper, like root bound ... I would rethink is my watering regime right if i see it in my garden.

You have a little bit high amount of nitrogen in your soil which causes nitrogen toxicity and it blocks other nutrients to get in. Also your plant is very tall, on the top she gets too much light but she doesn't on the lower part. How can you fix? Try not to feed with nitrogen anymore, and water your plants with runoff 30% maybe to flush out buildup from your soil. You should've started training your plant way before tho but you can still tie her down to even out the canopy. Good luck!

There are two issues. One: The is "tip burn". This means, you have overdone your fertigation. Two: There might be a bug, wandering around your leafs. Look closer!

Cookies Gelato Auto RQS. Second week of flowering. I'm using an SF1000 light at 30cm and 90% light intensity. 900 ppfd on the top of the plant, and around 600-700 ppfd for the underside. Temperature in the tent is 19°C at night and 21 to 22°C during the day, with 60% humidity. I can't get any warmer, it's cold at home at the moment but it doesn't go below 19°C. For the water, I use a PH of 6.5 and I use biobizz fertilizers 1 time out of 3, with a dosage slightly lower than shown on the diagram. Btw I have 4 plants in this tent, they are taking up space and the leaves are touching each other, I don't know if this is bad or not and how to regulate this.
