Nutrient Problems Please Help

Magnesium deficiency isnt necrotic patches ..... magnesium deficiency will not display necrosis in a situation such as this one ... (research Mg deficiencies...) .... some good advice though buzzo ... cut the feed of water in half (only a ltr a day for now....) feed them salt-based nutes every 2nd feed ... with a water inbetween ... after you flush them with very dilute nutrient solution .... (use a LOT of water and keep the ph at 6.0 with a low ec.) .... as buzzo mentioned .... CalMg+ by gh is a decent product but you do not need to feed them cal/mg constantly ...... if your garden has a TONNE of hid lighting hanging over it .... you will only need to add extra cal/mg once a week at most .... most likely once a fortnight at that size of a plant .... also ... budwise is not necessary, i hope you havent been regularly feeding them the shit .... hydro stores are quick to oversell .... to make a sale ..... Coco hogs Magnesium .... not sure about the potassium .... (as mentioned above. ..) when a plant is sick ... dont prune back half-dead foliage in an instance such as this one ... leave them on .... pruning off the half-dead leaves might make the plant look healthy but its just a cosmetic fix ...... the plant can utilise stored nutrients in the foliage ... hope that helps bro ....

 

Keep it stony and keep any questions you may have rolling in,

Riddled with Fungus Gnats....Guarenteed.!

Treat straight away.

 

Coco tends to hog Potassium & Calcium.....So first thing you need to do is flush with lower strenght nutes, and at the same time put neem oil or NIlnat, or Gnat off in the feeding to kill the Gnat Lavae.

 

1.Check the accuracy of your P.H. Meter

2. Drop the Cal Mag, you have probably given too much and caused nutrient lock out.

3. flush with food and Gnat treatment heavily...Plenty of run off.

 

Magnesium def. & gnats give very similar symptoms in blotchy brown spots on leaves.

It's very easy to misdiagnose as an amateur.

 

Search this site for Gnats ETC there is a wealth of info here for all.

 

Hope it turns out ok for ya!

 

thankyou smarty pants... your spot on! yer got shitloads of those gnats you mentioned. noticed them in my sativas pot. i was using pyrethrum. but yer shits no good. so ill get onto that oil. otherwise ill cut back on calmag and see what happens. thanks a bunch man. never knew about the gnats been such a badie. cheers

On just viewing the photo, I would suggest an Iron deficiency.
