Dr. of Marijuana ...NEEDED...

1 Month old plants apprear to be needing a little help
advise would be looked on kindly

Looks like nitrogen def. Either the plants need more nitrogen or they need the PH lowered.

You know you have to feed them right. You can't just stick them in potting soil - they'll die.

Btw, if it is nite. def, the leaves will yellow and fall off from the bottom up, until there are no more leaves and the plant dies.

looks underfed and ph is probably out of wack.

It's also really small for one month old - unless it's from seed and the seeds took a week to gem and your counting that.

yea counting germination. ok so general spec is potted in canna soil and being using canna coco A + B under HPS 400w bulb around 1m above plants because i was scared they were getting burnt or heat stress. only fed plants twice with half strenght solution because i killed my first grow by overfeeding but they experienced similar faults whilst doing so... strain is northern lights


i have ph tester solution how would you get an accurate sample and correct ph?
