i am not a stranger to growing however this is my first time trying solo! today i went out and bought a 400 watt HPS/MH (using hps) light and i have it about a foot and a half above 4 1 foot tall plants. Two of these four plants have a fair bit of curling and arent as shiny/healthy looking as the others leaves. what can i do to turn this around and get them healthy again?? ive attached a picture of the worst plant and the best plant along with the nutrients i will begin using when its time for the next watering. on a side note when can clones come out of a humidity dome under a 60 watt fluorescent and be put into the environment the others are in. SECOND PICTURE HAS THE TROUBLED PLANT
I'm no expert or anything I'm new to this forum and I have only 5 harvests under my belt using only cfl's .. That being said picture one isn't close enough for me to make out any curling but picture two looks like its wilting and judging from the size of the plant and the size of the pot you might want to consider repotting before she goes root bound if it hasn't already. Hope that was helpful
#1 that pot looks way to small for a plant that size probably becoming very pot bound this will eventually cause your plant to out grow its roots sustainability for feeding it, for the best plant concentrate on your root growth this is one the most important aspects!! you want fat babies let them have room to feed! #2 looks like over watering, possibly a few deficiency's or over fert the pics are not clear (remember plant drooping is over watering, leaves curling up is either 1 or a combination of heat stress, Calcium or magnesium deficiency calcium def will lead to mg def often come hand in hand) i personally stick to hydroponics for its ease of control lets you be very specific with your feeding and is alot easier to correct problems.
ive been trying to piece together my own web but there is a useful table on there to help diagnose any of your problems that we cant see either post clearer pics or use this to help you Mr B's A&E - For all your Budding needs....
