Chemical burn or def?

Hey Doctors, pls help me out here.

These 2 clone candys came from an already flowering week 3 plant. I´m still learning the clonning process, thats why i cut them, to get exp.

They where on 24h clf for 4 weeks(2 weeks for rooting and 2 weeks for vegging with "Hesi root complex") and now they are on 12h 250w hps with "Alga bloom" for 1 week.

They are 5 - 6 fingers away from light and they have a fan blowing at them.

Yesterday when i visited them they where like these and the leafs have some kind of bubbling going on..:

Plant 1



Plant 2




Bubbles on leafs are like these



Could it be a chemical burn or a Ph burn?

Are the bubbling and the supose chemical problem related or they could be 2 diferent problems?

Many thanks Docs.

so guys, i´m thinking in treat her with agla boom and hesi complex root. what do u think?

right now she is only with alga boom. should i flush first?

thanks

Check you soil ph.

Hey guys, here is an update.

This is how they look yesterday.
Plant 1:





Plant 2:





They where watered friday.

They have grown, but leafs are still too yellow and leafs on plant 2 are shrinking...

What do you think? Pls let me ear your opinion.

Thanks

It could be a big lock-out right? how many days does it takes for it to go away?

I would say a ph issue have you been phing your watering and feeding?

looks like light bleaching, do some research to confirm.

there could have been a water, last monday, where the PH was not in the best level, but on the last watering (friday) it was good (6.35PH).

Didnt know that light bleach existed.

They say that the leafs turn yellow but the plant still grows. Plant 1 and 2 realy have grown since last friday.

Going to back them off a little bit from the light and see what happens. Thanks for the tip
