Thank you for the reply.
The problem is that I changed my nutrients mid flowering.
I had some deficiency and the old nutrients were in bad shape (bad quality, shady provider, etc)
So I changed to these and I'm trying to give them a good nutrient concentration.
Thank you for hearing me!
I have powder feeding by greenhouse fertilizers which have a chart with the recommended EC and g/L for each product.
The G/L don't reach the required EC... Barely half.
For week 8 of flowering (oficial chart):
Hybrids:
0,5 g/L
EC: 0,7
Booster:
0,6 g/L
EC: 0,6...
Hello everyone!
My plants started to show some yellowing and brown spots on their leafs.
These are 3 white widow autos from dutch passion.
First I thought it was something related to the nutrients I used (they were in bad condition). So I changed to a new and more reliable brand and bought...
Now that I take a second look they might be small..
But it's my second plantation ever
The lights are 240 w of Samsung lm301h (high efficiency)
I put a cup next to the plants for reference.
15L fabric pots.
The size looks normal to me.
Before i planted some "xxl" autos (psycho xxl pack by BSF) and the were a bit bigger.
I also had some problems on my previous plantation.
This ones are mostly indica so they dont grow that much.
I also had no problems with this plantation (before...
Yea, my guess would be that the previous fertilizers were not working alright so there is some deficiency.
Plant 1 and 2 are much greener than plant 3. You can barely tell by the images tho.
But the purple borders in the leafs on plant 3 make me scared. Can that be a toxicity? (Too much of...
These are 3 white widow autos by dutch passion.
They are planted on fabric pots with soil (Mostly peat) mixed with vermiculite (66% bagged soil, 33% vermiculite)
I'm feeding mineral fertilizers. (Ph around 6.5)
Used to be top crop and changed to powder feeding by greenhouse.
With top crop I...
Peat moss based soil (klasmann ts3).
It's the only plant with these symptoms from a total of 4.
Should I give them something extra? More of my basic nutes?
I recently had a plant with clear signs of magnesium deficiency (yellow between the leaf veins (lower leafs) and almost purple stems).
So I fed the plants with epson salts. I did it with all of them as a preemtive method.
Now this plant (started flowering not long ago) show some signs of...
I think it's a magnesium problem.
I've read a follow up of a dude using the same nute brand as me and he had that problem.
The nutes we use (top crop) doesn't have magnesium. It does have N tho.
So I did a foliar and normal feeding of epsom salts.
Hopefully that helps.
These images are from...
Leafs are starting (slowly) to get light green and even yellow in one of my 4 autos.
Some leafs in the bottom turned totally yellow and were pulled out.
Ph is measured.
I use some comercial nutes and use the recommended measurements (going for the lower side)
Temp and humidity is ok.
I use...
I have 4 plants indoor and just this one shows these problems.
I give all similar doses of nutes.
This one showed problems from the start.
(General malformation, 2/3 pointed leafs, strange growth pattern)
