Haha ya I've done a lot of reading and will do more it's just hard and confusing when people say so many different things in what it is, I trust ur judgement u seem to know ur shit, ha ya I would to want my temps any colder than 65 during 12/12. I been trying to keep it around 75 F but the new bulbs I got t 6500k but don't produce as much as the 5000k ones so u put one of those into the mix to get more if a spectrum and heat it up a bit in the room. So do u honestly think I nute burnt my plant or is lacking mag? I'm flushing it out right now and late tonight or tomorrow morning I'll slowly start adding the nutes back to it and keeping th pH at 5.8 and let it go up 6.2 to get the nutes it needs. I dunno what else to do haha. Hopefully my new seeds come in soon. What kinda hydro system r u growing in?
What I think....?
You said the original damage was probably due to stress from transplanting....???
By transplanting, I assume you mean putting the rockwool or rooting sponge into the pots of hydroton???
To me the old damage looks like nute burn -
but it's very minor and I wouldn't worry too much about it.
The new 'damage' (damage is an inaccurate description because it's so minor) looks like magnesium deficiency.
THE CANNABIS GROW BIBLE by Greg Green has a page with drawings of 11 fan leaves.
One is a healthy, normal example.
The other ten are drawn to show how different problems make the leaves appear.
MAGNESIUM DEFICIENT is the only one where tiny bleached spots are SOLELY on the edge serrations of the leaf.
The others have random light spots, or faded tips....
But I'm new to this....
I can only tell you what my books seem to indicate.
ALSO....
I honestly believe that, sometimes, doing nothing is the hardest thing.
Waiting and watching, when you suspect your plant may have a problem,
is difficult and frustrating.
I'm saying all this because I think that your plant has very little wrong with it.
The plants we see on sites and in books are perfect examples
often they are expertly pruned to exclude any damaged looking leaves
or even improved with photoshop manipulation.
Blemishes and imperfections are normal.
Specially for novices, like the two of us.
Your plant looks fine, to me.
Why not sit back and give it time to sort itself out...?
Often this is the least worse option.
