On select leaves only. Predominantly on the fastest growing plant.

Dynagro products: Protekt (a silica product), Grow, Mag Pro. Of 3 Northern Light plants and 4 plants in the tent this is the only one with enough visible effects to catch my attention. The other 2 NL plants are very small and less developed but are more uniformly green. Everything going in is between 6.2 and 6.8 (soil grow), mostly towards the 6.6/6.8. This plant has exhibited a brown speckling from very early on. This picture was day 20, a day before getting its first nutes.View attachment 392905

I use Dyna-Gro also and never had a problem.That 20 day plant shouldn't be having problems this early so its kinda strange.It looks like cal def but this usually doesn't happen until later on.The only thing I do is add some extra cal/mag because the amount in there nutes is a little on the light side.I also have my PH at 6.4 or 6.5 so you may want to lower yours a bit.

Ah, Dynagro. I was told to use 5 ml of Grow as per feed chart. That your recipe?

 

[namvet25]

Yes,follow the 5ml chart.I raised the dose when mine hit 5 weeks and they seemed to like it.

I just don't get why my autos are so persnippity. I've grown tomatoes, peppers, cucumbers, zucchini, lettuce and they look normal if not all uniformly pollinated. Two cannabis grows incl the present one and it's adventure city. Actually the first panned out alright and an issue I had was my fault. This grow the one plant from the same strain as last time is fine. Amongst the three Northern Lights plants this grow none sports a textbook look. 2 are dwarfed, the other has weird leaf stuff going on. And Northern Lights are supposed to be one of the easiest of an easy to grow weed to grow. I mean what is that black shit on the third pix above? My water's good enough to grow all sorts of stuff.....grrrr

Is it just water damage?

 

[blessedinwashington]

About the genetics? No. Water damage comes from water left on the leaves and getting burned by the light. I've gotten worried about it before so now I make sure no water is left on the leaves after I water. Heck since it is just a few leaves, I would just take them off.
