Yea my clones are pretty weak they haven't even been growing that much they are like midgets. I didn't know i was supposed to give them nutrients so early. They are growing little pistols on the top and some on the bottom, is that a sign they are in the flower stage? They need to get bigger if i wanna get any decent yield I was wondering if It was too late to give them fox farms Grow Big.
I guess the soil had some fertilizer in it but it wasn't doing much and to top it off it lowerd my ph to 5 and locked out nutes so i had to give it dolomite lime to level it out.
they look really healthy. I wouldn't worry bout their size just yet, worry bout their ph, like u said, and be gentle with nutes. What lights are you using? You can always make them stretch a little by moving your light source a little further back. But really give it time and i think you'll be satisfied
