What's up? I can't believe I didn't sign up to this forum sooner, seeing as I almost always come here for 'real advice' which alot of other grow forums seem to lack significantly. So basically, I'm a long time reader, first time poster.


Right now, my friend is growing six AK48, plants are 25 days old from seed ( or when they first sprouted). 3 of them are doing fine, tallest one is about 6-7 inches. The other three are not so good. I've noticed that they are significantely stunted, in otherwords, not growing at all, but not dying either. The embroytics are still in tact on all six apart from one and that is one of the healthy one's. This leads me to believe that I doubt very much it is a toxicity because I've come to understand that toxicity causes other vital nutrients to be locked out from the plant and as such the plant uses up energy that it isn't getting, by eating its leaves closer down the plant. Obviously this makes sense in a way because the lower the leaves produce less energy so they are in a way expendable in times of crisis. Am I right in thinking this?

Apart from being stunted, there is significant purpling of the stem and leaf stems which points to them not recieving enough of a nutrient, of what I'm not sure. The most stunted has the darkest discolouration. One or two seem to have very abnormal growth, the leaves are not smooth like the healtier plants, they are some what ruffled and scaley and certain parts of the leaves are bent/curved or distorted. This could be because as younger seedlings, the input fan (pc fan) blowing on the plants could have been enough to damage the leaf ligaments, which would lead me to belive this being the case, seeing as the most stunted plants now were the two closest to the input fans at the start.


Right now, a mixture of BioBizz Light Mix and Canna Seedling Mix is being used. Should have been all BioBizz Light Mix, but a combination was all that was available at the time. Plants were all started in smaller pots and then repotted into the 14 litre pots once roots were seen coming out the bottom. The plants have not been fed at all yet and the medium has been evenly watered throughout every few days. There's no pictures as of yet but I hope there's enough information for somebody to give me a good diagnosis.

can i ask what are his temps and humidity? for lights on,and lights off mate

welcome to the site too

Hey man, thanks for the quick reply. The temps are (on average) 75-79 degrees fahrenheit day and night, sometimes creeping over 80 on occasion but never going above 85 or below 70. Humidity fluctuates but is on average 33%, never gone below 20 or over 55.
