    I am at a loss as to what the problem is. I have been reading that ph is not something to be concerned about in soil. But the plant is showing a few different deficiency signs, which keeps leading me to a ph problem when I am studying what it might be online.

    How far is your light away from the plant?

    Also ph tested the Tomorite feed mix and that is also at 6.6.

    Stop using tomorite. If the soil was good to begin with, the plant will not need any food until just as it starts to flower. As to the amount of water to use, water until you get a little run off, so you know the water has gotten right to the bottom of the pot. Then leave it about 2-3 days, until the pot starts to feel light. Then water again.

    Theres no need to over complicate things-they are hardy plants, and often fussing over them will cause more issues.

    Once you start to see preflowers, at about week 5, then start with a 1/2 or 1/4 dose of feed.

    What type of soil did you plant in?

    I did a very minimal grow my first time-garden center soil etc, maybe take a look- https://www.thctalk.com/cannabis-for...ery-minimalist

    I did not just start feeding for the hell of it or to complicate things. The leaves of the plant where showing signs off Nitrogen deficiency according to numerous pictures and posts I had read, so I feed with nutes one time. Then all the other different symptoms started to show that would suggest ph problems. So here I am giving as much info as possible to try diagnose the problem. Its in Terra Canna plus which I am regretting buying If I am honest. I have also grown in regular garden centre compost outdoors and had no trouble whatsoever.

    Im no expert but can’t you simply just give the plant a flush? Or does that only work with coco?


    Legalise it, Don’t criticise it

    That is what I did in the end. I flushed her last night. So just wait and see what the next week brings.

    I use the ISH 150 PRO and at seedling stage i keep it 30'' away and let the girls grow into it, I think 8''-12'' maybe a little too near.(I just read though on their site that they say you can run your light closer to the plant,) but I still think 8-12 is a little too close. My first plant I grew with the QB LED got badly burnt because I didnt have the light far away enough.Get someone elses opinion first that knows more than me about these lights but i'd raise your light to at least 18-20.
