Stunted growthpots, tiny brown spots help please!

[ryanisgrowing]

Hey guys I’m growing a couple auto gorilla glues in coco, it’s my first grow. I’ve been feeding about 250-350 ppm @ 5.7 pH, using canna coco line nutes with cal mag. I’ve noticed one of my plants hasn’t grown at all the last 2 1/2 days and every time I check on it I find more of these tiny brown spots. I didn’t germinate in rockwool(regrettably) and planted right after germination in a paper towel into their 3 gal pots(again regrettably). They are all on day 14. Help me figure out what’s wrong, is it a nute deficiency or nute lock? I know I’m probably over worrying but I wanna catch and fix the problem while it’s just starting instead of of when it really becomes a problem. Thanks everyone!

To early for defiecency or lock out.Could be a little nute burn spots from feeding but other than that they look ok.Check out our coco thread to find more info on growing in coco.Also make sure your entire pot is fully watered and continue to use cal/mag.

Hey namvet, thanks for the reply. A couple more of those spots popped up, I’ve been feeding about 250-350 ppm in the last week, it could have something to do with the nutes cause early on I botched a feed and accidentally gave like 450 ppm(my tds meter wasn’t calibrated properly), I’m afraid they might be little stunted because they look a bit small for 16 days. Here’s another pic I just took

Some of my lower leaves also got spots like that. It was from getting some nute solution splashed on them. How often are you feeding them and how much? Also what light and height from pot? Just to give you an idea even thou mine were in autopots. I watered my pots with 1.5L of light nute solution and planted the germed seed. At like day 3 from sprout they got 500ml of light nute solution, day 7 750ml-1L light nute solution, day 10-14 depending gave them 1L nute solution

Ohh.. that totally makes sense.. Because I have been getting some of my feed on my plants by accident when feeding. I'm feeding about 350 ppms right now at 5.7 pH. Using a mars hydro 600w about 25 in. above them, I was only feeding about a liter at first, but the last feed I decided to wash it with 300ppm feed because I had been only watering in a small circle around them. I got it to runoff but just a few drips and ran out of water. I also experimented with foliar feeding rhizo which probably wasn't the best decision because, but I sprayed them with about 75 ppm of rhizo adjusted to 6.2 pH. Was that bad? Here's another pic, she grew some more brown spots, any ideas on what i should do?

To be clear I used rhizo last week, I don't think the spots have anything to do with the rhizo and I know they can absorb it well, I'm thinking that you're right and that it was from my other nutes getting splashed onto the leaves
