First time grower... is this plant a lost cause?

[BananaShark]

Hi, I'm new to all this as its my first grow so my first post is an obligatory "First time grower, help me" post.

The lil' gal is straggly and has what I assume is bad nutrient burn. I flushed it 2 days ago as most of the leaves were starting to yellow, but now its ended up like shown. I'm also scared I stressed it too much and now its hermi'ing. I've been using HP Perfect Technology Mico as feed.

As for the strain, I *think* its Pineapple Chunk, it was from seeds I was given from a friend (who also messed up a grow and ended up with a hermi that self pollinated)

If you have been feeding it with only micro nutes then it is quite possible you have nitrogen toxicity. Hard to tell since you don't have many fan leaves to make a good diagnosis. Looks to me like it is starting to develop an overall nutrient deficiency caused by some sort of lockout, with my first guess being nitrogen toxicity due to being supplemented with micro nutes.

Provide some more info on your growing medium and watering schedule.

Looks like nitrogen burn to me. You're feeding it too much nitrogen. Dial it back with some tiger bloom or possibly open seseme. They have everything your plant could need without burning it. Are you using miracle grow or something? That stuff is horrible for cannabis

I agree it's probably nitrogen burn. Either that or some kind of deficiency. But yea we need to know his water schedule too

I think I've approached this far too casually, I tried to keep it simple but I'm appreciating now the nuance and care needed.

The medium is basic potting soil with perlite mixed in, in a fabric pot. The watering schedule has been roughly once every 2-3 days, determined by checking if the top inch or so of the soil is dry.
Pic is of the feed I have (hopefully the image quality stays high enough so it can be read), I've so far only used the Micro (they're all opened, but only the Blooms looks it from the pic), though I can see it has 2% nitrogen compared to the 1% of the others.

I'm more surprised that this nitro-burn has happened immediately after a flush with just water (~PH6.5), I was expecting having been flushed with just water to possibly help this issue rather than exacerbate it.

Flushing helps but the damage was already done. Hmmm do you have proper drainage in you pot? Cause I water my plants everyday. At that stage you should be watering every other day at least. I think you just aren't giving it enough water to help with all the chemicals so they're burning your plant. Try watering more often and you might see better results. Also how big is your pot? It needs to be at least 3 to 5 gallons

The pot is 5 gallons and I've actually been scared of over-watering, before when I'd water most of the time water would start leaking out of the sides through the fabric. I'm not sure how to do/judge drainage, the pot on a mesh thing with wheels, so has around 3cm of ground clearance if that helps.

It would be helpful to see what the plant looked like before the flush. I don't see indications of hermaphroditism.

Some of the symptoms look like light burn to me.

I don't see many signs of excess nitrogen, like dark green leaves or downward curling leaf tips.

I suppose many growers worry about overwatering. When and how much to water changes during the plant's life. During vegetation, we want to encourage the roots to go deep, so we let the soil dry between waterings. Soil moisture increases with depth, so the roots go deep to seek it. It's called hydrotropism. The situation is different during flowering, however. The plants don't form many new roots, just as they don't grow many new leaves, because the priority changes to growing flowers. At that point, the amount of foliage and the vapor pressure deficit (VPD - which describes the difference of the moisture in the leaves compared to the moisture in the air) are the main factors that drive the plant's water usage.

Oh, actually i do have a pic from the day before the flush probably should have posted this before. It was yellowing before, but way healthier than it is now, with the light at the same height/intensity.

I think it is the lack of leaves hiding it and I mainly suspect it because it is being fed only a nitrogen supplement during a time when it should start transitioning away from added nitrogen. The lack of leaves makes it very difficult to diagnose since those affected leaves are technically the lower leaves, but are also so high up you can consider them upper leaves too.

Going just off this image and watering routine it really looks like she is just hungry for anything other than the extra nitrogen.

You have any pics from a few days before this one? Maybe up to a week before it, preferably one right before discoloration showed.

I agree that it needs a balanced diet, even though it still doesn't look like nitrogen excess to me. That said, it might not show nitrogen excess if it had the other nutrients it needs. They still need some N during flowering. I only skimmed the thread, though, so I must've missed the part about it only getting N. It's making more sense now. I also agree that the lack of leaves makes diagnosis more difficult.

The yellowing at the upper curve of the fan leaves indicates light stress to me. The light might not be too intense for a healthy plant, but it looks like it is for this plant. So, I recommend reducing the light slightly till its health improves. The key thing to consider is how all plant growth factors need to be working together in concert. These factors include light, heat, humidity, nutrients, etc. Too much or too little of any of those will result in an unhealthy plant.

The fact that the yellowing is more pronounced the closer you get to the light suggests its light burn just like @LoveGrowingIt stated. The green leaves at the lower part of the plant makes that pretty obvious. I don't see signs of N toxicity. I see light burn.

P.S. Next time, don't take so many leaves off the plant. You've certainly gone too far with your defoliation.

Why would the leaves prior to flush pray if it’s light burn?

It could depend on when the picture was taken. Also, light burn can develop over a long period of time before it shows. Poor nutrition reduces a plant's ability to use the light it's getting, which also worsens over time. A good transition from vegetation to reproduction is important.

I can see a little bit of everything going on here , its not one or the other its all three, slightly overwatered, light too close or too bright and wrong nutrients . any bark/wood products in the soil, (which i think includes coco) holds onto a lot of nitrogen and calcium and a light thats too intense will start to stop the uptake of nitrogen and then after the leaves have gone light green it will stop the uptake of potassium which will cause yellowing usually down the edges of the leaf. if its interveinal it could be lack of iron/manganese?
then theres the stress of changing its environment near flower...did it come from somewhere with a poor light to somehwere with over 1000w ?
