All I grow are autoflowers and by this point you should be feeding, I recommend Botanacare pro grow bc it's just fish mulch and nitro 60ml per USgal, water, drain, fill a 16oz cup of water and add a small amount to cup and feed them, get a pH meter and check the run off when you drain as it's very important that you use clay pebbles for good drainage, you want to shoot for 6.2 but 6.0 to 6.5 your ok but not perfect, when there done with there stretch and in full flower I give a light flush check ph and I use Atami Bloombastic same drill but only use 30ml per USgal as if you use to much you will fry your plant, I keep it very simple bc autoflowers hate stress, make shure you have good airflow, you can buy a cheap battery powered ph meter on line, you will ALLSO need a good glass or jeweler's loupe, remember go light on nutes but I start to feed lightly at 21 days or 3 sets of leaves so I do think your plants need some food or nitro bc there drooping, don't get discouraged folk think weed is easy to grow and it is, but you need to grow properly or all you will have are sick plants, chopped this critical mass plant yesterday but am having problems finishing up a chem stomper as the pH is all over the place but it's an F1 and has been giveing me grief since the rip, it will finish in the end and now I'm going to try some new breeder from Maine called Wicked Pissah my cousin sent me called cherry pebbles. Pic 1 critical mass pic 2 the bottom half of chem stomper the leaves yellowed a bit bc I have been having trouble keeping ph straight and drainage bc sometimes the roots wrap around the clay or it's just not completely stable as is an F1 tester.
