    Nutrients: Should I follow the recommended g/L or EC values?

    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.

    Feeding or light issues?

    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...

    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...

    Am I feeding my plants right?

    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...

    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?

    Leafs going lighter green

    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...

    Seedling with strange colors (white marks) + stunned growth

    I'm using 15L (4 gallon) smart pots. But do you use soil? Maybe it's the combination of overwatering + big pot.
