Hi guys got 9 plants under a 400w mh will be changing to 600w hps after flip. 5 are on day 38 but have another 4 in there on day 31. Got them in 6.5 litre pots should I veg them to 6 week and 5 weeks ? Or 6.5 weeks and 5.5 weeks? Not ideal being a week behind but only option at the minute. what’s the max veg time on 6.5l pot before they start to get rootbound?
