Hello experts, novices & total newbs!
I am a total newb & I need some help identifying this problem, I think it could be a Mg deficiency but I'm not sure.
This is my first bundle of bagseed joy and most likely the only soil grow, I'm switching to hydro after this.
Here's some details about the grow:
They were started from seed around early to mid March under 27w cfl's.
Apr 14 they were put into tent with good vent and a 400w MH.
MG moisture control soil w happy frog 6-4-4 nutes (which I only used twice & very little amounts)
PH of water is around 7.0 plus or minus a few pts here n there. (Is it bad to fluctuate water ph a little?)
I noticed this problem a few days ago, I just transplanted em to bigger pots yesterday hoping it might help but it doesn't look like it did anything today.
At first I noticed 2 tiny yellow spots on one of the original fan leaves then it started on the opposite fan leaf. Now another plant is doing the same thing.
Any info would be appreciated thx.

nute burn . Give a good flush , then only give water for couple of weeks then start of on 1/4 strenth nutes , did i read that you using Miricle Grow . That stuff is dangerous . Try and stay away from that stuff when you come to transplant into bigger pots , Also try to get your ph down abit more . I always aim for 6.5-6.6 . Hope this helps

yeah I heard that MG soil isn't the best but I'm not really looking for perfection on this one. Just wanted to get one successful grow under my belt before I go hydro. I def need to get some ph solution too. thx again.

Looks like nute burn but dont flush it will just make thing worse, everytime you water them your actually feeding them. I would recommend just watering them as you were doing before. You may not need to give them food for another month or two since MG already has some in it.

Use finely granulated dolomite and mix it in your soil.

The lime keeps your ph in check all the way through the grow. :)

Good luck Man :)

If you were to use dolamite gardeners lime you would place innew pots before you do a transplant , And as for you saying your not looking for perfection , thats wrong in my eyes as what happens if yo only get 1/2 oz off say 4 plants then that would be a total waste of electricity to be honest . Always aim for top quality
