help!!!!

iv just bought a 100x100x200 tent iv just potted 6 afgan kush im using multipupose compost from bnq its a peat based all round potting compost an im using a 400wt sun master light an im using canna terra vega some leaves are turn yellow after only 2 days am i worrying for nothing??

is there good air circulation there? See if you don't build up heat.

You have given them nutes already? How old are they? What's your temps what's your ph?

the temp is fine im leavin door open on tent abit an got big fan in there i think the ph is ok its only my sec grow an dont have much money to spend an yh iv feed them the canna veg already not to sure how old only got the cuttings the othere day sum 2 are small still

...probably overwaterd. ...are you working with clones?

i grow afgan lower ur ph to the 6.2 range your going to see yellowing on lower leafs run a 18 / 6 cycle for veg it appears they love it water every 4 days stay low on your nutes u want something like 1 - 4 - 0 nutes with high phos
the yellowing of lower leafs gives u a false indicator makeing you think nute burn , over watering keep them lights 1.5 ft above plant for a few days then lower them to a foot above plant
i run 2000 watts and have them like a foot above plants there growin insane

PS: leave them leafs on plant till they fall off plant will absorb all nutrients from them leafs then take them out
