    Default Week 4 Flower and some leaves at the top are brown

    I've been reading on here for ages and my first grow with a 250w HPS has been going OK, i've noticed some weird leaves in the last few days and wondered if anyone could help?

    I've been using canna soil with ph 6.1 - 6.5 feed from the canna range aiming to keep the first run off around 6.5ph which is has been

    Without the direct light hopefully that gives you a better idea of what I mean and the overall condition of the plant, thanks again

    Thanks for the reply, I've been using 6.5ph water overall and sometimes less if the run off gets a little high.

    They do have a slight bit of nute burn but I thought I'd corrected that.

    I'm using a 250w hps and it's about 10-11 inches away from the light with a fan blowing over the top.

    Ok mate so you are not adjusting the PH of the feed before you water them.... just a little unclear here still buddy

    have you donr the back of hand test? stick the back of your hand level with the top of the plants an keep ther for 10-15seconds if feels to hot on your hand then its to hot for them.

    whats your feed made up of? what soil you using?? and what nutes??

    also get those pics

    Thanks again, I really appreciate the help.

    I am adjusting the Ph as it's about 7.8 out of the tap and sometimes with nutes it drops to 5.

    I've been doing the hand test and it feels ok to me but I did burn a leaf early on so I thought I'd learn my lesson.

    I'm using the canna range, 1 water then 1 feed at half the lower advised rating.

    The last week I've been using the canna flora, boost, very small amounts of pk13/14 and its grown in canna pro soil with fabric pots.

    As soon as I'm back from work I'll take some pics, don't want to lose my first grow

    i dont grow in soil but have followed plenty the grows. so soiler grow will advise better. think it bit early for the pk if you on the bloom. how long since you flipped to 12 12?

    so you your using a bottle or PH up or PH down then??? this is important to know. you should not adjust the pH of the feed in soil, soil will naturally buffer the ph to whats it needs it to be.
