CoronaGrowerstarted grow question 5y ago
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??

If it's the old leaves is because of the stage of flowering it is in...as she is bulking up she is pulling more so once medium is dry the next water source is the older fan leaves/water leaves...#happy growing she looks healthy

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.

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?)

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!

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

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?

¿Quema de nutrientes?La Orion F1 se ha puesto de un día para otro como veis en las fotos!
:-(
Creo es quema de nutrientes
Uso solo abonos orgánicos de Biobizz, el sustrato es todo organico (ver Semana inicial de Germinacion del diario) y pH controlado
¿Qué me recomiendais que haga con ella?

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?

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it
