Weird new growth on flowering plants

[Abraham]

In flowering for about 4 weeks and new growth started at the top of the cola on three different bag seed plants. It is under a 50w led grow light, it was a bit close too the plants but even one of the shorter ones did the same thing. There is not much air flow and a general 'potassium rich' synthetic nutrients (3.1.6) has been added to the feed 2 week ago (low doses, and recently increased). Tbh I don't trust the nutrients, but i don't know why.

Looks like it's revegging, what's your light cycle like? Light bleed into the grow space can also cause it.

Good day,  I don't think that light is powerful enough for flowering, that's why it's revegging

Could be a light leak or a change in the light cycle.

Does not look as if you have a proper tent, so it is 100000% dark when the lights are off?

Does any light leak in? Perhaps from a window, under a door etc. etc.

 

If the plants are not getting 12 hours of more of darkness, they could be revegging.

it is definitely revegging.

you need to check your timer and make sure it is working correctly

if you use a pool pump timer with the dip switches, you need to make sure that every dipswitch is working correctly.

i have 3 of those at home that function correctly, but some of the dipswitches fail to make contact and if that is happening to you, its revegg central.

or you forgot to switch your timer back onto auto after a night extra input or something.

either way. you must plant some new seeds as this harvest is tickets.... they will need to transition back into flower and kinda just keep you guessing for the next few months
