So I have 4 ladies in their 6th week of flowering.
They are grown in a good soil with terrible amounts of clay balls (40%). I know this was a mistake, but I'm too far in to change anything about it.
I am feeding with BioBizz starter kit (Flower food, bio heaven and top max) and adding cal-mag at 1ml/L. I water them with PHed water about 2-3 times a week when soil is dry.
They grow under a 250W HPS, 12/12 cycle where the lamp is about 50-60cm above the tops.
The cabinet is vented with PC fans. No trouble before so I'm guessing its alright.
Also on saturday I flushed the soil, then fed half dose of normal about an hour after.
What can this problem of mine be? I do realize it looks like nuteburn, but why the bright colored leaves?
