Light leak?? HELP!!

queennoob · Dec 31, 2025

Hello. Super new at this. 3rd batch. I have them in an insulated wood barn. . I tried to have a couple different grows together in same space separated by black felt to prevent light leak. Oldest plants seemed rdy to harvest. Orange pistils and trichomes. But when I cut a few branches and started trimming this is what was there. No bud at all. Is this light leak? Help. Do I just wait for them to re-veg? WILL they re-veg? Do I just pitch them? Please help. I’m at a loss.

They dont seem to have bulked up , they fatten up the most in the last 2-3 weeks so i think its either too early or they got stressed and stopped growing a couple of weeks ago. I cut my first grow down as soon as i saw amber tricomes , then i found out they will go amber on the leaves first , a couple of weeks before they are ready.
have your lights been that high all the way through , they seem to have stretched up to the light and perhaps they didnt get enough light to develope properly ? i like to keep mine short and about 2-3 ft tall

Not even close to done and looks to be a very low powered light source.

A flower needs to bulk up and this happens after the pistles retract and change color. W

Here is a close bud just waiting for the final finish.

Notice that the pistles have retracted and the bracts are swollen up and lumpy. Just waiting on final ice up and amber trics

I have the lights turned down to 80%. Having temp management issues. So running them at night to help with that. sometimes the heat gets too high if at 100%. These were planted in June. photoperiod. So you don’t think this could be light leak from the curtained in area that runs 18/6?

again more powerful lights and smaller temp differences between lights on and off. but mostly when there is not enough light they will stretch to no end.

Plants and not just cannabis exhibit the presentation on known as stretching when the light energy hitting the plant does not meet it's requirements.
The plant spends extra energy trying to grow the leafs up into the light by extending the stem length. This causes the node spacing to be extended with lots of wasted space between the new growth and will hamper the ability of the bud run to close up in flower.
From the looks your energy level has been deficient the whole grow.
It does not matter what the reason. Heat, cost, no more outlets in the room this will need to be fixed if you plan to grow weed.
Suggest possibly a minimal grow with one plant and all the lights in a closet with a fan to control heat.

Possible mite damage with those weathered leaves and looks like a problem with mag and K, indicates one of a couple potential problems going on like pH off, nutrients fighting amongst themselves, or uneven soil (pocketing/channeling). Give that plant a good looking over though because I think mites are causing your most grief.

It would help to lower the lights so they're closer to the plants. Two feet is a good distance. I'm also thinking the pot is small for a plant that large.

We have had these little webs coming up on a lot of the nodes. With little tiny bugs. I’ve been using Neem oil. I will check the ph. Thank you so much. Any tips on dealing with mites?

thanks so much. The temp thing has been a constant struggle. And the abundance of plants was an accident. Put down a handful of seeds and normally lose half. But all of them lived which caused the full house situation. Thanks again for feedback. Would you keep them or pitch them?

I’ve had to bend them sideways because they grew so tall. and were touching the lights. But will try to move lights down.

when you have mass plants volume can make up for it.
if you get 20 grams per plant thats almost 3 lids.
but if you are expecting 2-3 lids per plant not gunna happen.
Also the whole learning thing. flower them plants. get some light on em. see how they grow. keep them green.
see if you can get and swelling at the end.
