I am growing 4 big buds in soil (10L pots).
i grew them from seedlings. i vegged them for 5 weeks on flourecents and 3 days ago i went into flowering and changed the lighting to HPS 400W.
today in noticed all the plants are turning light green.
except that they're looking prety good.
i keep the water on 6.5Ph, and the temp is around 25c.
what can be the problem?
also - last year i had 2 growing cycles and on the second one i had the same problem, at the end the plants were really yellow and the harvest was poor.
thanks.
