Mg deficiency? pics...

wootas · #1 (**permalink**) 07-28-2008, 06:00 PM

I'm using promix with more pearlite added, mixed with lime and a premixed organic fert with over 15 ingredients. I just changed from using spring water to using distilled with a few drops of ph down in it since I put the plants into larger pots. I had this same problem before when the plants were smaller... Also along with the browning between the leaves, some of the edges are curling upwards, and the tips of some pointing down.

I don't think people around here like reading more than 1 sentence questions because when I ask something I can barely find an answer for a fairly extended period of time...

I looked through the post of all the different deficiencies and mine only looks like heat stress or bleaching but it's occuring only on some of the growth further down in the middle of the plant, not the new growth. The leaves affected are far from the bulb, 18+ inches. Only thing I can think of is too low humidity, my room is air conditioned and it stays around 76 with the humidity between 30 - 35 usually sometimes less sometimes more. I don't foilar feed them at all, should I? Any ideas are appreciated.

My guess is the 15 kinds of nutrients in your mix is burning them. What is the pH? If it is between 6.2-6.8 i.e. it is fine, I say fert burn.

I highly doubt that because they were experiencing this problem moreso before I had potted them in my mix. They were previously in a peat / pearlite mixture with no built in nutes of any sort and they developed this problem anyways after about 3 weeks. It's different than the conditions I get from chemical burn, I've had it on the same plant..

OK Between those two mediums you should have been at different pH. What is the pH run-off now? You also have slight heat stress so it is too hot wherever they are at some point in the day.
