PLease Help ! Northern light auto

Yes, I agree with what the other 2 respondents have written, but I would add going to half strength nutrients at this size, also strongly urging you to go to an 18/6 light/dark schedule, no plant is "designed" to grow properly under continuous lighting and believe it or not, but plants do actually need to "sleep" and undertake certain metabolic processes that they can not do during "lights on time". 18/6 is a scientific fact derived through 80+ years of cannabis research and is not a random number and is equally applicable to both auto flowers and photoperiod plants in vegetative growth. I would also suggest filling your pot right up to the top next time, the extra room would provide much more space for root growth, speeding up plant growth and leading to potentially larger plants too. It also reduces the risk for nutrient salts building up to toxic levels in the substrate and would negate the need for the foil, as the plants would be sitting up higher, allowing for more reflected light reaching the plant. Filling the pots right up does not take up any more room in your grow space and will allow for much bigger plants, as plants can only grow as big as the root system can support the above ground growth. Hope this helps,....... Organoman.
