Iron deficiency?? I'd just flush em with 1/4 stregnth nutes and give them a few before bumping back up to full strength.

Ya, somethings going on, is it your bottom older leaves or is it on New Growth too?

Residual salts can build quick depending on how you feed. Check out "make it rain" thread for a great way to feed and water

Every 3-4 days wait till their nice and dry and allow a little run off

Not bad looking. Nothing major. Over all green and healthy.

Water only for a couple or three waterings with a little extra run off should help clear it up.

Most likely just a bit of salt buildup.

I’m going to flush them buddy later they were due to start the flush next week anyway so jst start the process a little early thanks for your advice appreciated

That's light burn to me,either spilt nutes or your not moving them enough or they're drying out too much and the leaves can't protect themselves. They look fine really, no problems , if it bothers you cut the burnt bits out

I'm not saying to flush. Just water only as they are due a watering. I dont believe in starving then at the end. You can't flush nutrients. The mobile one just move to new growth and the immobile ones don't move.

I like to keep them green and happy to the end. The smoothness comes from the dry and cure.

lol bruh come on! wasnt it you who made a "too many cooks not enough chefs" comment earlier? definitely not light burn.. if the lower leaves are affected you can cross that off the list.. and cutting the burnt bits out is not going to solve any issues so forget that until you get things fixed..

On the second set of pics you see the "burnt" tips and the yellow margins? that leans towards Potassium.. some of the tips also appear to be going up which could suggest an Mg issue.

Whats your medium and ph looking like? What nutrients are you using? What kind of buckets/containers?

Overall the plants look pretty good but if you wanna try and be done closer to 3 weeks than 4-5 you gotta get this figured out ASAP...


Just being honest... you can FORGET about the plant being done in 2 weeks. Youre getting close but you've still got some work/time until chop. Also, while you dont want to over water you can also run into issues by repeatedly letting things dry out too much.

Good luck and if this is one of your first grows you should be hella proud of yourself champ!

Opinions are exactly that, based on experience,first pics in my opinion is light burn , what caused it is another question, haven't looked at the other pics until now, op needs to put up more info. Just because they're lower down doesn't mean it didn't happen at a different time and not noticed etc.
