Dying yellow leaves on one out of two plants under same conditions?
LaBruckstarted grow question 5 years ago
One of two 3-week-old autos is dying with curled leaves turning yellow and brown spots. They've been fed equally, so can't figure out what's wrong. Temps, humidity, PH and light distance have been in order. Watering with tap water left overnight, no veg nutes yet.

You have a few problems going on the yellow from the bottom up older leafs dying off first look like a nitrogen deficiency. The yellow and brown spots on leaf is a manganese deficiency.
I’ll flush my medium to make sure I’m not locking out any nutrients. Then I’ll start with a light dose of nutrients. Also most important of all because it happened to me . Is to check or re calibrate your ph pen . My pen went bad given me similar problems. You can check out my moxie to read what I did to fix my issue . Hope that helps good luck to you ✌️🏾

you should pH your water since tap water is 7-9 pH and ideal is 5,5-6,5

Looks like they might need some cal mag. Try grabbing a bottle and I believe they will bounce back! Cheers and happy growing!

FeedingHow often am I meant to feed and water my plants. I do water my plants every 3 days and after every three feeds I flush. Concerned as all the bottom leaves in my grow are turning yellow but the tops are okay. I do give them Calmag so I’m not sure what the issue is here.

drooping leaves, cold weather and high humidity, is it overwater problem?I think i´ve overwatered my plants, so it´s is cold (16 C / 60 F) and relative humidity around 70%-75% . old leaves are turning yellow. I´ve lowered the water frequency and wait the soil to dry before water again but leaves are still droopy. What do you think? is it overwater?

Yellow Leaves AutoflowerNovice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

best leaf insects repellentI have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else?
White vinegar with dishsoap didn't help much.
The bugs are: grasshoppers, stinkbugs, spidermites & fungus gnats.

Leaf tips yellowing. Overwatering? Or nute burn?I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Yellowing on leaves tips. Should I start feeding her?Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

Warum werden die Blätter auf einmal so schnell gelb und welk?Hey, meine Hawaiian Runtz ist Ende 4. blütewoche. Gießen tue ich alle 4-5 Tage mit 2-2,5 Liter Wasser und 6,5 ph Wert, immer ziemlich identisch mit Terra aquatics ph Tropfen, also sollten ph Fehler ausgeschlossen sein. Temps am Tag ~28 und nachts 26 grad Celsius. What’s wrong?

Identifying the cause of stressDoes anyone know what I’m seeing with the leaves in these photos? The closest I’ve been able to guess from online resources is maybe sulfur deficiency, but to my eye it doesn’t seem to quite fit any of the broad categories. Perhaps just general under-fertilization?
