This is my first grow so I have some doubts.
Growing in an Organic compost potting soil mix
Also Growing in a 5gal bucket or (Space bucket)
Using Lotus Nutrient as my source to feed the plant with distilled water
The plant is currently in week 4 of Flower as of today 08/29/20.
Genetics: bag seed (so no really sure)
So I fed my plant nutrients on 08/24/20 and the run off results were as follows: pH 6.4-6.5 and PPMs were ranging 1550-1580ish. I watered with no feed (pH of water was 6.6 and PPMs were 20-40ish) on 08/26/20 and the run off results were as follows: pH ranged from 6.3-6.4 and PPMS ranged from 1220-1250. Which is good as it means the plant is up taking nutrients. But now the problem was yesterday 08/28/20. When I watered the plant again with no feed (I used the same water from 08/26/20) the results of the run off water surprised me. The pH stayed the same ranging from 6.3-6.4 but the PPMs also stayed within the same range as the other day which was around 1220-1250.
Am I experiencing a nutrition lockout? Or could it be a salt build up? Any advice would help tremendously. Thanks in advanced.
