Dear,
can you pleas give your opinion...
First time growing and now is 4 week in flowering.
Noticed that lower leaves start having yellow edges and become all yellow and falling down. Upper leaves are for now ok.
Ph - before watering 6.0 - run of from 6,8 - 7.2
Nutrients - Biobizz Bio Bloom 3ml/L, before in vegetative - Biobizz Biogrow around 900-1100 PPM. Nutrient and GHE Ph down were added each watering.
Today was checked runoff and PPM was really high from 2500 - 3500 ppm - I think this is a lot too much - how much is ok 1300PPM?
But how i was looking on internet this is not nutrient burn? Or my thinking is wrong?
2. Temperature in grow box is 23 degrees Celsius when lights are on and when are off may fall down to 14 degrees Celsius ( I know this is to low). Fans are working 24/7. Is better to turn off fans for time when lights are off? This wont decrease temperature so much.
Humidity is 35-40%.
What in your opinion is wrong? Do you suggest flushing or just adding pure water-and how long?
Thank you very much.
