Hey Guys, This is my first grow and I think Im starting to get into some trouble. Can you see what Im doing wrong with these to cause the curling and color changes? The leaf is starting to yellow, the sides are curling up and the tips are curling down? Is it lights or nutes? Im lost?
70/30 coco pearlite Spider Farmer SF4000 set to 40% Hand watering every 2-3 Days with 50% nutrients -Cyco Grow A & B -B1 Boost -Dr Repair -Cal Mag 18/6 Light Schedule with good circulation and 60% humidity and around 24 Degrees Celcius
check your ph of the water you are using. often if the ph is not in range, the nutes are not readily available. Also you might want to use RO water if you can just to make sure water is not a problem. check your light....should be about 18 inches from the top of the plant and set to 50-65% eliminate the dr repair, and b1 boost for now. Double check your cal mag and nute A/B doses--maybe too much or too little. just double check your math. Give it 7 to 10 days. post pix day to day if possible.
In my experience, MJ will grow with general health and vigor with a range of nutrient solutions and soil conditions IF ENVIRONMENT IS GOOD. If it is too hot or inadequately ventilated, the most precise use of the fanciest nutes won't help. If the damaged growth is most severe directly beneath the light or furthest from the fan then heat is most likely culprit. Thermometer may not be reading the hottest part of your tent. Good luck. You may be pleasantly surprised as plants often rebound and have robust flowering.
