Deficiency on sprout?
ShaderKongstarted grow question 3y ago
Deficiency on a sprout? My Chem 91 seems to be doing great but the tips of the new leaves are starting to show some yellowing. Is this something to be concerned about?
Gave it a bit of water yesterday. Any help is appreciated.

I don't think this is a deficiency.
Just keep it to water only it will grow out of this in a week.
FFHF soil or FFOF soils are hot. meaning to much nutrients for sprouts.
Autos also have sensitivities to extra feed as well. they like a lower nutrient solution.
this is a good reference point to use for feeding guidelines with autos.

It could be overwatering or you said you droped light a bit, first week she was more than fine.
That plastic cup has to be light as air before watering, it's easy to screw up, you have drainage ????
Please don't put any feed or mag yet, your soil is more she needs, adjust light, rethink aeration !
All the best !

Sorry, just had a look at your diary. If its an auto flower I’d say that Fox Farm’s soils are a little intense, I use then and have had this before as well, it will be fine. You could try cutting with coco coir next time if you don’t want to see that, plant will be fine though.

What type of soil? That young I’d be more leaning toward the soil being too hot as opposed to deficiencies.

Dealing with Nutrient Burn and Salt Build-UpI've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.

What could be causing these spots and burnt tips?I noticed this starting this morning, the pH was 6.3 and 210 ppm. The water was about 7-10 days old. So I figure water change time?

Leaves tips look burnedAny suggestion of how could make her look healthier? Tips look burnt and leave color is not great. Also my plant is very short, 25cm. I didn't feed her any nutrients so far, only water pH6.5. The soil (atami kilomix) was heavy fertilized with bat guano. Is she needing something?

Top Leaves are becoming yellow from the inside out.Hi, anybody know what the problem is with this plant? The top leaves are becoming yellow/white from the inside out. Also the leaves have a different shape.
The plant is in open soil and I give her water and sometimes some veg nutrients. Thanks in advance. (Last picture)

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Strange leaf shape, who has encountered this and what came out as a result?1. Am I right that it was just overwatering?
2. Who has experienced the same thing?
3. What are the chances of growing a healthy plant?
I appreciate all the responses, this is very important to me, thank you!

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Yellow leaf edgesI have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?
