yellow tips have pics

hello I'm a first time poster but need some help. In the pics the two bigger ones are mothers to the rest, and the last one is when I started to bud the clones about a couple weeks ago. I'm growing train wreck fem and a couple of my plants are getting yellow leaf tips its hard to tell from the pics but just the tip is burned, also one of the big ones is getting rams horn leaves a problem i've had before. I'm feeding them general hydroponics switch to full strength last week. they are all about 3 feet tall in two gallon pots under 2x 1000w hps. I'm worried I slowed the progress of my buds they're starting to look good. any help would great.Thank You

Not looking bad, but likely there is a rootbound issue. I have no problems transplanting up to three weeks into flower, but the fresh soil must not contain time-release nutes.

With virtually every crop I transplant at two weeks into flower with no adverse side-effects, except that they do stretch a tad. An extra week in flower, and they fill in nicely.

Might have been going a tad heavy on the nitrogen, (deep-dark green, burned tips) When you say you switched...you did mean a switch to flowering nutes, right?

yes I switched nutes and light to 12/12 on the clones the large two have been budding awhile and are in 5 gallon pots but have slowed way down. It's first time with yellow tips but have had alot with the rams horn leaves, I know I could be yielding way more.bummer
