when do you think is good to give plants grow big

3rd week or 2nd week?

any help LAWL

depends on soil you are using. I am using grow big nutes for the first time, with fox farms ocean forest soil and I used 1/3 strength ( 1/3 tsp per gal) on my 2nd week and it burned a couple leafs. on week 5 now, using full strength, but every other watering instead of every watering as recommended on the bottle. plants are doing great.

ya dude im using fox farm ocean forest soil its still been 1 week and 1 day but ya when do u think its ok to give it on the 2nd or third , and should i start giving it every other week i water

just wait a few more weeks i will post a pic of when i started giving mine grow big it was either the first pic which was 1/09/09 or the second pic which was 1/15/09 or in between but i would wait till they are around that size and start with like a 1/4 strength once a week then move on up as u can se ur plant wont get burned by the nutes cuz honestly ive never burned my ladies with ff nutes

i forgot to post pics

first pic 1/09/09 second pic 1/15/09

ohh yaa my babys are way to young then so like ya ill give it when its that big.. how old are they anyways in that pic 4th week or 3rd

about 5-6 weeks cuz it kinda grew slow at first then we had a nice heat wave and it took off

3rd wek for sure, the soil has bat guano in it so it already has a decent amount of nitrogen. and i would start off with a weak solution. what i did is after i burned them a bit from feeding too early, about 3 1/2 weeks in i gave 1/3 tsp per gal, feeding 1/4 gal per plant. mine are in 3 gal pots. i water every other day. the second time i added nutes (4th watering after starting the feeding schedule) i kept it at 1/3 tsp per gal, next time fd just water, then the next feeding i used about 2/3 tsp per gal, then just water and finally 1 tsp per gal every other watering or for me every 4 days. the bottle recommends 1 tsp per gal every watering, but it wasnt designed specifically for marijuana. so i'm gonna keep it at 1 tsp per gal every other watering unti i start to flower. then i'll switch nutes. This is actually my 1st time using grow big and ffof soil, but its working very well for me. always better to give a little less than it is would be to give a little more.
heres my current grow if your interested, not too far ahead of you, i'm going into day 37 since seeds sprouted.
