I'll be CRACK!

WEEK 5 ****DAY 29: 30/4/18**** Last week Tuesday I noticed some lime green tips on a few of the top leaf tips, I was thinking it was either nutrient burn or light stress/burn so I decreased the nutrients back down to 2.5 ml per litre instead of 4 ml per litre and raised the lights back up a few inches, but despite doing this I noticed towards the end of last week that there were a few lime green/ yellow tips on the new growth now, so now my guess is that it is in fact nutrient burn and I was not checking my PPM, I have hard water where I am so that was my mistake to not check, I was giving around 1000 PPM with out knowing. So for the last 2 days I have given 1 litre of plain pH 5.8 water per day only and will be dropping the nutrients back down to 1 ml per litre for MEDI ONE and 0.6 ml of Liquid Weight and that will bring my PPM down to around 400 - 500 PPM. As for today (Monday 30th April) I will not be giving any water, because I have also noticed a slight sulphur/ egg like smell from the bottom of the fabric pot I am using, so I have decided to ease off the frequency of the watering to allow the pot to dry out a little and allow more oxygen for the roots. I have also put the pot on top of a spare oven rack I had to raise it a little off the surface to allow air circulation around the whole pot. ****DAY 30: 1/5/18**** 10AM - PLAIN pH 5.8 Water - 1 LITRE I started to notice an egg like smell from the bottom of the pot and run off water, since then I raised the pot a little off the floor on an oven rack and let coco dry out a bit by not watering for 48 hrs and this has helped very well, the smell is now gone. ****DAY 31: 2/5/18**** 10AM - 500 ml of plain pH 5.8 water I have done some more LST today. Nutrient feed will be tomorrow as the last 3 watering's have been plain. The amount given will be 1 ml of MEDI ONE & 0.6 ml of Liquid Weight. People recommend to feed nutrients every watering when using coco so from next week I will start to do this and keep an eye on my PPM. ****DAY 32: 3/5/18**** 10AM - NUTRIENT FEED - 1 ml of MEDI ONE & 0.6 ml of Liquid Weight - pH 5.8 - 1 LITRE - 400 - 450 PPM ****DAY 33: 4/5/18**** 10AM - 500 ml of plain pH 5.8 water Since I brought my PPM down the new growth is looking really healthy with no yellow tips. My tap water is hard so when I added nutrients it sent my PPM way over the recommended amount for my young plant. ****DAY 34: 5/5/18**** 10AM - NUTRIENT FEED - MEDI ONE 1 ML & LIQUID WEIGHT 0.6 ML - 1 LITRE OF pH 5.8 WATER She has about 15 bud potential bud sites now. New growth is healthy and green. ****DAY 35: 6/5/18**** 10AM - NUTRIENT FEED - MEDI ONE 0.5 ML & LIQUID WEIGHT 0.3 ML - 500 ML OF pH 5.8 WATER ****WEEK ROUND UP*** This week I learned a few things about PPM and how it is important to track it through the grow, it is the answer to why I ended up giving my plants nutrient burn, I now have purchased a TDS meter and will be tracking PPM from now on. From next week I will be giving nutrients with every watering and see how things go, it has been recommended to do so by fellow growers, just keep an eye on PPM, I will be giving my normal dose of nutes for 1 feed and then 1/2 dose the next feed e.g Mon - 1ml - Tue - .5 ml - Wed - 1 ml etc.
