Hey peeps im having an issue my babies:sad: I noticed last week both plants on began to turn yellow from the bottom up. The bigger of the two is in its 2 day of flowering now and i noticed that its turning yellow from the bottom up... The smaller on wich is 40 days vegging is almost all yellow:-( I dont know what going on. i've been feeding them jacks classic 20-20-20 and have a c02 mix going on too. I had a problem with gnats comming in the soil so i added white sand but the problem began way before i did that. please i need your sudgestions to save my girls

prob should have been getting more n and less p k, have you flushed them through?


I've been giving them plain water the last 3 wattering. i just foliar feed them a few days ago. I thought they might have had a Magnesium deficeincy problem so i gave them some epsom salt both foliar and on the soil. Also my PH was above 7 according to a ph meter i have. Today i feed them some more nutes and added some vinagar to the water to lower PH to atleat 6. dose it seem like a nute issue or magnesium... man i dont wan them to die. Please any input would be great:sad:
 
i would have flushed them well, got ph sorted then feed them something more like 20-10-10, , it def looks like they need food, are these outside or under a light?
 
hey,

need more info, lights, water/soil ph, water sced etc........

first off the look a bit on the small side for 40 days, so usually yellow leaves means its lacking Nitrogen, but could also b a ph prob which stunted growth before.... what has your water ph been all a long??

what strain also....

also when u see probs like this as the guy above said flush asap with clean PH'D (6.5) water wit 3 times the capasity of the pots..

get your ph right and flush and give some grow and bloom nutes..
 
They are inside under 12 26W CFL 6500K. The water has a PH of 6.5 and as far as for as the strain i have no idea, Bag seed from some Sticky Crazy potent Indica. Would the white sand ontop cause any problems? So basically o should take like 2 galllons of water with a 6.5 ph per pot? there are i bealive 3 or 4 gallon clay pots. How much water should i use? Should i drop the PH to like 5.5 incase i have a PH issue?
