how bad is a posphorus deficiency?

  1. So, by looking at some pics on the forums i came to the conclusion my plant has a Phosphorus deficiency. Possibly also too low rootbal temps.

    I will not be able to feed my plants for 2 more days. How badly will this hurt my plants? They used to do really well but since the conditions changed (lower temps), they don't seem to do as well anymore.

    Also, should i flush with water ph'd at 6.0 before i feed next time or not? i have a fertilizer with an npk of 4-6-6, plant are one week into flowering (not showing any sings of sex yet).
     
  2. What is your runoff pH? You usually don't fix a nute deficiency by feeding, the fert probably has enough of the nute already in it, the problem usually is uptake is locked out due to a pH imbalance.
