Cant identify the problem

Hello everyone,

it’s been almost a week and half that my plant started to show signs of deficiency, but I’m not being able to fix it.

Im using BioBizz Nutrients.

During the last week I stopped feeding the plant when I though it was suffering from nitrogen abundance, after, I was told it could be missing photassium, so, I resumed the feeding by giving her 3ml/1L of biobizz bloom + 1ml/L of biobizz grow and + 2ml/L of biobizz alg a mic.

My lights are the hydro mars ts600 and they are standing between 35 to 40 cms to the top of the plant

Before the plant started to give problems I was always alternating between phed plain water and nutrients.

edit: some of leafs at the bottom also died.
And in my opinion the plant is lacking smell?

thanks for the help!

Are you watering until you have runoff? could have a salt buildup causing a lockout. Do you have a EC/PPM pen to test the runoff values?

I have one, not sure if it’s 100% reliable. I will water it tomorrow with plain water, I can try to measure it.

I’d follow the biobizz feed chart, I’m not familiar with the line. Also, make sure your fabric pot is not sitting in its own runoff, that can cause issues as well. They sell plant platforms at grow shops for under $5, or you can get creative and make one yourself

Honestly im super confused right now but as you advised I will just feed her as I would normally do for a week 6/7 age plant. I will give an update in a few days.

thank you so much for the inputs

In an earlier comment, you mentioned that someone said that you may have had a nitrogen toxicity ? Too much nitrogen can block the uptake of potassium. Excess nitrogen also creates more demand for magnesium, causing the plant to want more. Check this chart out. It’s possible that too much nitrogen is causing both of your issues. It could still be something else, but this chart does lend some support that theory.

problem is that I’m not sure if it was the case or not. This is my second grow and I had no issues at all on the first, so, I’m still a bit bad on identifying problems and solve them.

On the last two weeks I have barely gave her nitrogen, but yes, I guess it could be it

I was looking at your 1st grow yesterday, and it did look much better than this grow.
All changes you made after the 1st grow would need to be established in detail if possible. Especially changes to the way you fed them. My guess is you are feeding more this grow or added something you didn't use last grow.

Scientific method - we test things and analyze the results to come to our conclusion. Go through it step by step. The advice that was given to measure your runoff ppm would be to help confirm a lockout or not. It would also be a good idea to check the ph - for the same reason. If you continue to feed, and the issue gets worse, it might indicate a lockout, from an imbalance of feeding and resulting buildup of salts (or your ph is out of line). Flushing a hungry plant will not fix the issue, but flushing salt-laden soil is the general process to remedy that issue, before continuing to feed a better ratio.

Have you been taking notes and charting your feedings? Did this issue first coincide with you doing something different in your process? Taking notes/keeping a journal is incredibly helpful for new gardeners to be able to go back and find mistakes, or improve their process for the next grow. We often learn by making mistakes, and then correcting them.

I know right?

Thing is apart from temps (weather is colder now) I didn’t change a thing. But I will for sure just try to get to where I was in terms of time line, reestablish things and try to still get something more or less good from this one still.

You are completely right, it’s a learning process. I always keep a diary of what I do and I even take pics in a regular basis. I always follow the same feeding chart and I always intercalate feeding with plain water, this started to happen when I saw some top leafs with a strange behaviour, curling down, and as I said before, I asked for help and I have been told it was a nitrogen burn. To solve this, instead of feeding (water-nuts-water) I gave her 3x plain water and resumed the feeding with some concerns on the nitrogen still. And at this point the colouring stuff started to happen.

Currently I have the progression of the issue pictured and when it started to happen.

i should have just kept to the“script” since last time I used this feeding chart I had no issue at all.

This is the ppm of runoff today

Ph of the runoff was a bit low somehow - around 5.4 to 5.8

the plant seems to be better now.
