So I'm coming to the end of flowering. My Northerns are 6 weeks into flower and last week recieved their final feed watering to starve them for the final two weeks, possibly 3 weeks. I do however have a growing Ca deficiency problem and a constant Mg problem. I do use Cal/Mg regularly with my other nutes.
My question is Should I use Cal/Mg til about a week before harvest? And what happens the the final product when the Cal or Mg may not have been fully flushed or used up? I'm just not sure if it is more benifical to treat the def or starve the plant?

Why are you cuttin the nutes off so early Chrissy. I use Cal-Mag+ up to the last feeding, How long are the flower period for the NL?

8-9 weeks I'm just all confused I haven't cut my nutes yet but I was planning on 2 weeks of strait water so the plant uses everything up.

Based on my 60 day flower, I'm feeding up untiul day 53. Only cuz the last two weeks they do a LOT of their growing. So i wanna make sure the food they need for the last explosionn is available.


Edit, last feed, day 50, flush start day 53

See my plants only need water about once a week I think that could be what's screwing me up. I don't use flushing agents though no.

well, I'm not sure about the frequency thing, and what it can cause, i use soiless.

What water do you use.

Well, i'd treat the plant, whatever you do because you have 3 weeks left about right?

The pots are 3 gl. I water till water comes out the bottom then let them drain for an hour. RH is 45% temp is mid 80s at the top. I water again if the top inch is dry.

imo, there is no need to stop with nutes right now. wait a week, then go straight water. that should be enough to both feed through the weight gain, and flush the excess.

hmm, I only water with a measuerd amount so i can water more frequently. I dont know which is better, but I dont have runoff and i know that can be trouble, but my plants are alive long enough to experience and defs. maybe 500ml in 2 gal pots.
