Firstly, thank you to Muddy, you seem to be the man here, so if you say don't worry, I won't worry.
Time for a quick update and a couple of questions. I gave the older girls their first nute feed about 26 hours ago and they seem to be responding well. I gave them 1mil of Old Timer grow per litre of water, erring on the side of caution. The younger ones just got water with a bit of root stim and bio silicon.
My landlord informed me he will paying me a visit in about 4 weeks, just as my plants should be bursting with buds/trichs/wonderful smells etc... it's not like he'll do an inspection or anything, he normally pops in for a chat, coffee and a joint but I don't want him to know I'm growing in his property (I haven't told him about the cat yet which is breaking the terms of my rental agreement - oops), so my question is, can I switch off my lights and fans for about an hour maximum without causing any detriment to my girls as even on the lowest setting, the fan can be heard humming in the hallway. The tent is in my bedroom which he won't go into so I'm just concerned about the noise and smell leakage from the tent with the fan off. He knows I smoke weed in the flat (apartment for all you Americans...) so maybe if I have a joint on the go he'll just think the smell is from that and not the (hopefully) lovely green garden in my bedroom.
OK time for the obligatory pictures. I have a slight issue with the plants in the party cups, the leaves are starting to yellow, this could be due to nutrient deficiency because they've been in those cups since 27th April without any nutes. I'm not over bothered if they fuck up, I'm not expecting anything from them, it's just a lil experiment. Should I be looking at the sex of the older plants yet, they are about 3 weeks old - all the seeds were fems but I know this isn't 100% guaranteed? Unfortunately, I don't know the PH of the water, I've been winging it so far and will have to do so because of fundage issues.
