Mystery Problem - Need Some Serious Help!

2023Yaboy · Oct 7, 2023

Just starting week 6 of flower, and I’m seeing dry, brown, crispy edges on multiple leafs but not at all bud sites. I originally thought this was nutrient burn so I flushed and proceeded to feed nutrients at a half rate. I now believe it’s either some sort of deficiency or a PH imbalance. However, I’ve been using water from the same tap throughout the whole process with no issues. I’ve been having this problem for over a week now.

I thought it might be a cal-mag deficiency but it’s not the whole plant which doesn’t make sense to me? It could be due to heat stress during the night but I really do not now. This is the first plant under my care so I’m essentially clueless.

If anyone knows how to help please let me know I’ll provide photos below.

Emerald harvest, micro and bloom late veg rates so (in the same order): 1.50ml and 2.75ml, with 2.5ml of shogun zenxym and 1ml of amino treatment bro

In a litre of water

Not familiar with what your feeding you should be using flower rates by now not late veg rates. I would like others to look in tbh see what they say as too me it looks overfed ( to much n ) but I don’t enough about animo treatment to comment on it

Sorry mate I meant late flower*

I had considered overfeeding so I only fed it half what I was supposed to, but the issue only got worse it’s a mystery to me bro

I did think too much N but all I’ve given it is P + K

How often are you feeding? How often are you watering? What is the media?

Once a week, water and feed at the same.
I’m growing in multi purpose soil

I should add that over the past couple weeks, due to the issue starting, I flushed because I went to harvest to early I then flushed again as to ensure I done it properly. I then gave half nutrients and left it for a week. I’ve fed this morning at the full rates again because I thought it may be a deficiency due to the flushing. But I haven’t seen any improvement.

In the beginning I noticed the plants leaves slimming and getting thinner, I couldn’t find anything on this online so decided to leave it. Then, after all my efforts i arrived here

It's tough to say without knowing the nutrient and water retention properties of your soil, but my guess is that you're both over-fed and over-watered, based on the condition of the leaves. If I'm in an amended soil (I don't know if you are), I might only feed two or three times during an entire soil grow. Measuring the EC or ppms of your runoff water would give you a better idea if that's the case. The miniaturization, thickness, and texture of the fan leaves suggests over-watering to me. Over-watering is usually caused by either watering too frequently, or not having sufficient drainage in your containers. Hope that helps.

It’s highly possible this is the case, however, I would’ve thought the flushing would’ve prevented this problem? Over-watering I believe is playing a part for definite however, but the dry and crispy leaves remain a mystery to me I’m unsure if it’s expanding i believe I’ll have to update tomorrow to see the progression. There are also these spots that have started appearing?

They are very small but I hope that gives you some more inclination.

over feeding, too much stress..
too late to do anything about it,
plant is unhealthy and can’t really photosynthesis much etc take up nutrients etc,

As I mentioned before I would’ve thought the flushing would’ve prevented this issue? Other than that I’ve not fed any more that I was supposed to? Stress could be a factor but I doubt that would’ve caused such bad burning in only specific areas? Again I’m new to this so please correct me where I’m wrong

Adding on to the photosynthesis theory, the buds have grown themselves. But the problem is consistently getting worse day to day, so my concern was raised

it’s overfeeding and too much stress.. picking off leaves/cutting stuff/flushing/lights etc..
believe it or not
it will not heal itself..,

quickly looking i see nitrogen toxicity, overwatering, light stress, nutrient burn etc
