[robside]

My plants are 22 days old, their bout 4,5 ni.two of them are very fat, 3 are mush less fat and are yellowing, with spots, fat ones are dark green, curled down leaves like ramms horn, edges of leavves curling up, Ph unknow, soil grow, scotts potting soil, feed them MG 24-8-16 food. all same soil all same food, all same watering. Lights,first 9 days two 150w hps, now 400 hps with 55,000 lumes, have used 44wMH but to hot, growth to slow. dont know how to send pic's yet but trying to find out how

first problem is you dont know your ph. second if your feeding if plant food(not designed for cannabis) your going to have problems, possibly root burn which i think your going through. also you dont need to feed them plant food every watering. when you mix nutrients the water becomes very acidic which probably is doing damage to your root system. all of your plants are going to follow the same road as your bad ones. my suggestion is to read and learn how to grow cannabis rather than throwing a seed in some walmart nursery dirt and using nutes designed for the yard.

I have read almost EVERYTHING out there, BUT all i hear is (under ferd, over ferd, over water. I didnt buy wall0mart dirt!! I'm useing good soil and if i could figuge out how to post pic i would, plants are VERY fat, at least 2 of them, Thanks, BUT i didnt just through some seed in some cheap dirt. I have full light kit, 400w hps, and 400w Mh. fanns exust, lights. I was told that a food, nut. of 24-8-16 would do fine, Thinking of getting a 30-10-10- for rest of veg?? good idea?? also i just flushed all plant with 2 Gal. of water each.

imo "scotts potting soil" is wallmart, or target or even homedepot dirt, sometimes even in grocery stores. if you read everything on this site you would had known that ph is an important thing in mj grows and prolly would have got a meter before you started. owning a 400 watt light doesnt mean you have all the equiptment you need

Yea bro lol cigs is right, from how you been describing your grow and what ur using seems like u got a lot to learn.. ONE of the biggest mistakes noobs make are over under watering & over feeding ESP when your feeding in that crapy soil that doesnt drain as well as others and the salts sit in your soil for a while.. Best advice i can give you is go grab some FOX FARM ocean floor soil, transplant your girls ta that and get some BASIC cannabis nuets.. And make sure their in at least a 2.5-3 gallon potter.. And without a doubt GO GET A STANDARD PH TEST KIT ASAP!!!! PH is the most crucial aspect of watering and feeding your babies.. Second is your ppm but one thing at a time make sure your PH is between 5.7 and 6.3.. Good luck my man :thumbsup:

Heres what one of your girls could look like under a single 400w HP if you know what ur doing..

I use scotts premium for alot of my other gardening. I know its ph always runs about 6.4-6.8 I am sure on that. Wrong nutes.
