Yellow tips on new leavs in all plants. What can i...
OutForRealanswered grow question 6 years ago
Hello ! Your plant looks healthy to me , you' using a mix between light mix and bat mix so your plant should had enough nutrients for the 3 first weeks , I can see that you used Algua grow at half of the recommended chart which is a smart mouve however I don't bet on a Nitrogen toxicity , your plant would have been more dark green than that. No nutrients burn neither , to me your tips are not even yellow but pale green , let the new leaves the time to get bigger and if the yellowing spreads then you will have to worry. Also agreed with bulbi , you should hve continue the grow nutrients untill the 2nd week of flowering ( but if a nitrogen toxicity is proven then it's the best thing you could have done). I hope it will help you 😁👍

yeah man krippy your plants are really healthy. Thing is you might have done bloom nutes too early, but it's really something minor at this point, The leaves won't recover but as long as it's not spreading you're actually fine. These are going to stretch a lot so make sure you have plenty of calcium to carry them forward. flushing will make this worse most of the time just follow the soil's cycle. Just measure the PH a lot of root stuff will raise your ph you want to keep doing what you're doing 🚀

Hi @krippy! These are the first signs of a Nitrogen toxicity. Considering you're growing autoflowering strains, you should be very careful about the nutrient intakes, since autos are usually very sensitive to nutrients, they don't need such doses of fertilizers. In this situation I would flush the medium for 2~4 days with plain pH'd water then see how it goes. Don't give any nutrient until the new growth have stopped showing burnt tips. Affected leaves won't recover but the yellowing/burning should not spread if you treat your medium asap. Hope this will help, keep us up-to-date and happy growing 👊

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶
I can rub them off with the thumb with no sign

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?
