hi guys ive got spots on my leafs bit worried coz im 3 weeks into flower.
dont really know what to do as ive never had this problem b4 if i post a pic
will u guys have a look and tell me wot i could be and possibly how to get rid
of it cheers guys. only pic i got at moment is with hps on soz guys!IMG_0170.jpg
 
It is extremely difficult to tell exactly with the pic taken at a distance and under an HPS light, but from what I can see, the issue may be a calcium/magnesium deficiency. A closer up pic would help, particularly if you could turn off the HPS for the snap.

Either way, a bottle of calmag solution is something that a grower should always have around.

I agree with spek that its extremely difficult to ascertain spots in the picture you posted.


Try to get a good picture as there are a few issues that can be related to spots.


Ca and Mg supplements IMO are a must have for any growers. Novice or experts!!!

hi guys manage to get some half decent pic for u to have a look. also i just got cal mag + from plant magic
thats all they had at the store. i've knocked the nutes right back and im just gonna run this cal mag+ at 1ml per litre
gonna run it for about a week or so then gonna slowly get the nutes running back up to around 1.2 ec.IMG_0181.jpgIMG_0182.jpgIMG_0183.jpgIMG_0185.jpgIMG_0186.jpgIMG_0187.jpgwill they recover from this damage guys

using cal mag + withouts nutes for a week or so get my ladies back on track as i am only 3 and half weeks into 12/12

Great yields can be obtained without extra Ca and Mg I wasn't implying that they couldn't.

IME I've found that sometimes an Mg def can show up so people just feed more base nutes to compensate but sometimes this can work against you as more N and K can hinder the uptake of Mg.

So by just giving an Mg supplement additional to the base nutes it keeps everything sweet.


I personally like using mono Ca and mono Mg as too much of one can cause a lockout of the other.

Don't get me wrong most soil growers with the addition of dolomite lime will rarely see any issues with Ca or Mg. Unless their soil becomes really acidic.

From pic 1 of the second batch of pics, I'm going with high temps, low humidity and maybe some over watering.

And yes, throw in some cal mag in there too.

You're welcome.
 
My guess is a lock out of mag. Are you ph testing everything that gets poured onto your plants? A good ph tester solved all my spots on leaves issues
 
I add 1 cup of powdered dolomite lime to 1.5cu' of FFOF soil along with a few other goodies added to the mix. and x10 on using a PH meter and ph'ing to 6.5 every watering. I wouldn't dial back on the nutes, just do the cal-mag on a watering day, and resume regular water/feed schedule.
