What is this!?
IloveLEDstarted grow question 4y ago
Hello there. I have, as you can see a bit of an issue regarding my plant. What is this? As you might see, the lower leaves seems ok, and that concerns me even more. I have flushed her properly and then gave her adequate amounts of feeding. At first I thought it was lack of P.

Looks like a phosphorus deficiency. I would check run off ph with a calibrated tool first. Also seeing possible magnesium deficiency. I imagine the ph is out of range in your substrate. Hope that helps and is your issue. Good luck and happy growing 🌱🌱

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.
Thanks for help!

Browning, curling of Green Crack leavesIs this discoloration worrisome? Ph 6.1, adding 1tsp calmag to each gal, EC at 1.5. What's causing this browning? Seeing only on the Green Crack, mostly higher leaves, but some lower too. Does it need more or less of something? Leaves look "dirty".

Deficiencies? Brown spots, yellowing and purple stemsWhat is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Brown patches on leavesNoticed these marks on the leaves of the plant I've had problems with.
Any ideas what they could be?
The other two are smelly amazing and the single plant is so sticky! I think it might be the cheesecake but I'm really not sure, I won't make the mistake of mixing them up again

Brown spots, serrated edges curling up - calcium deficiency?This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up.
Is this just a straight calcium deficiency?

Ph issues part 2Hi guys! It has been a while after flushing, repotting into bigger pot with fresh medium and feeding her only with water. I bought Sensi cal mag extra and I need your advise if it can be used together with BioBizz nutrients, I could get only this brand in my local store

Maui Waui CA deficiency?Can anyone confirm or guess at the kind of deficiency my plant is having?
I am not sure if "hard water" (instead of RO so far) is the right answer or if I need some special sauce...
Thank you!

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.Week 7
