    My leaves look like they are coated with yellow powder. Need help identifying.

    These are the same signs that I had when I had the fungus gnats, I tried many different solutions but the one that worked best for me was a good fan directly pointed on the soil. Fungas gnat's larvae eat at your roots.

    Phosphorus deficiency and incorrigible pH

    Is this only the case for synthetic fertilizers or both? I mean, for liquid organic fertilizers, at different pH there not should be different type of microbs that poop different form of nutrients in a way available ( or not available) for the plants?

    Phosphorus deficiency and incorrigible pH

    Hey thanks for the advice! But note that the problems I showed in each photo were already present before I started playing with the pH, but the thing I will never understand is how it is possible that by watering with pH 4, the soil will still be at pH 8 (maybe there is so much life in my soil...

    Phosphorus deficiency and incorrigible pH

    The last 3 weeks yes all at ph 4, it's so low to try to lower the soil's pH for a longer time than just a day (anyway it is pH 5 once the water is in soil) , yes it is madness ph 4 but im out of my mind because I just can't fix this

    Phosphorus deficiency and incorrigible pH

    Phosphorus deficiency and incorrigible pH

    Im using distilled water, all my nutrients have acid ph and I’m not using nutrients containing humic acid anymore that should have an alkaline pH, my nutrient solution in the end has a pH of 3,5/4 by adding citric acid(my tester can’t get a value under 4). It seems useless how low the pH of the...

    Phosphorus deficiency and incorrigible pH

    Hi! I'm having problems with these plants (different genetics, same problem), and I don't know what to do anymore, I hope to get some help from someone better than me. My plants are showing something I think is a severe phosphorus deficiency with purple branches: 2 months ago I bought a cheap...

    Plant won't start flowering

    Hi, thanks for the reply! Yes, I thought something like that and that's why I wanted to specify it, even if the LEDs are 550w they are not comparable to the sun... but I didn't even expect them to stop flowering! Anyway, what is the best cycle for a greater production that I should follow? 10/14...

    Plant won't start flowering

    I apologize if I make any mistakes, but it's my first post. Hello! I have a problem with flowering, I have set the 12/12 cycle for about 2 weeks, in a short time the first pistils came out, but it is now a week that they have not grown and have remained millimetric, and some would even seem to...
