GO get a foliar like chi, and some flora klean or something like it. Water the plants, if possible with a nutrient flush like flora clean(fucking blue berries? wrong ph). Then after a couple days, use a foliar feed(not treatment). Chi/diamond nectar combo is what I used in the past(from General Hydro/works on soil plants to).

Once you have fed them one good spraying, wait two more days, then give them some sort of balanced feed. Nothing to agressive. Should be good then. Check for the light leakage, but I tend not to think that is what it is. I think You have just tripped out the plants with blueberries.

No light leaks period is the rule of thumb. Its been through a bit of shock, so needs a long period of no more shock to settle back down.

In reality(outdoors) there is always light leaks, stars & moon.

I do not think this is the issue. I think the roots/nutrients and ph are all out of whack.

Sure but outside the light issues are consistant. When you put a plant into 12/12 for a period of time, then that changes to random light shocks or even consistant light leaks which can seem like a 16/8 light regement to a plant, for example, that will send a plant back into revegetative growth, especially if as you say, the nutrients are out of whack. But aside from the cause, those plants are definately in revegetative growth.

Some strains are just sensitive to environmental changes and so if the grow method has been irregular in any way, they may be 'confused' and not flowering properly (become hermies..etc). In my experience, the plants that are switched back and forth from veg to flower to veg etc, eventually produce bad bud or hermies so instead just put the photoperiod to 24/7 regular light and wait a week, then take a cutting as a clone and flower THAT. good luck

this is the life of my plant : started in a closet with a 14w flourecent light, looked a little weak and thats when i shoved it outside it did great nothing was wrong till it grew 2' tall and i couldnt let me neighbors see it, so i put it inside with 4 26w daylight cfl's , everything was perfect added blueberries once a week and right before i started to flower added MG all purpose plant food once (which i thought was the problem) so i decided to flower so then i stuck it in the closet with 4 24w softer white cfl's i got my package of snow white seeds and decided to do that grow, so i didnt really have anything to keep out the light from the plant in the closet so i just thought about putting it a cabinet underneath my tv, it has some space in the back for light but other then that nothing else, ive been using just straight water no blueberries or nutrients for about 3 weeks now, so im really just going with the idea of light leak
