Buds are very small in about 7-8 weeks of flowering

Hello everyone,
I'm new to this forum.
I am growing 2 grapefruits from female seeds and 3 bubblegummers also from female seeds..
Grapefruits are supposed to be sativa dominant, and bubblegummers are mostly indica.
I know sativa has smaller buds, but i think it should not be that small as they are. At least one of them has like once bigger buds as another, but they are still small and i imagine how small they would be after drying... While bubblegummers have buds pretty big and they still need some time, as most hairs are white, grapefruits has pretty much brown hairs already and many trichs are also cloudy already.

They are all in same soil(Platron royalty mix), and all were fed with biobizz. Also on the smallest budded sativa, recently tips of bud leaves became brown and also later i noticed it on lower fan leaves. It could be over fertilized or underwatered or both. I think i did let the soil drain a bit too much before watering last weeks or so and before last feeding i gave them too much food i think.. They are not getting really any worse now, as i stopped feeding them about week ago and started to water a little more as i did.

I can post images later, but approximately avarage bud thickness is 2-3 centimeters, some less...

I would love to hear some opinions from experienced growers about it, becouse i don't think its normal that they are that small but so developed already.

P.S. I'm using 400w HPS, MH for veg. and 4x 30W CFL's as additional lightning by sides.

Well thanks for any answeres and help.

You forgot to say how long they've been in 12/12.

The Sativa dom. strain will finish later than the Indica. I think you are right to be concerned at the size you are describing this late into flowering. Pictures would help some. Lack of water usually causes some wilting before leaf damage. I have seen wilted plants rise back up after a good watering.

He said 7-8 weeks into 12/12.

Could be late bloomers. They might've gotten stressed somehow early in flowering and delayed. We might have a better idea with pictures. Maybe we can gauge what stage the plant is actually at right now. They may just be late bloomers. Hopefully they'll swell up for you soon, I'm sub'd. Hopefully I can help more with pictures.

you mentioned biobizz, which one are you using? im gonna guess and say your using the bio-bloom stuff which would be right, but i personally like using a mix of different nutes, not just 1 from 1 company.
you mentioned you have several of each flavor, are they budding at different speeds? like one bubblegum has 1/2cm while the other is at 2cm nuggs?
also the first response says "You forgot to say how long they've been in 12/12. " but you didnt mention them being in 12/12 light cycle, so im gonna guess you are doing 12on 12off, and that MH bulb you have for vegging isnt in use.another thing that could slow down budding is if they 12hours of darkness isnt dark (enough). is there any light getting to them? even dim light? the darker the better.

7-8weeks could be late bloomers, but thats very very late blooming. i mean usually youd have 2cm buds at 4-6 weeks of flowering, especially with a HPS bulb. sativa bloom slow, but the indica should be well into bud forming

Guess id check pH, make a soupier mix of nutes (add some sweeteners, a little of this, a little of that, make it comprehensive), id make sure the dark periods are truely dark, id make sure the light period has red red light (2700k spectrum only, maybe those cfls are daylight 6500K and are fucking with them?).

someone could probably give you a more accurate diagnosis if you had some pics up.

how large containers are they in? (the soil and roots in case im being unclear)

Thats a bit small ,should have more beef on them. What are the temps?

Hi everyone. I am at work now so i will post pictures later when i come home. I didnt understand what you ment with half centimeter about bubble gummers..They are not a problem they have big buds and still growing. Well this is my first full indoor grow but i have grown for about 3 years.. Last year winter came too early so after plants started to flower but didnt really develop any buds i put them inside under lights.. And they became pretty huge and fat. Had nice yield but way too many plants for the light i had..but i still got about 400grams from cca 10plants.. Conditions were similar to now but i added some ventilation with this grow.. Well i turned 12 12 7-8 weeks ago..should i start counting when i see hairs? About grapes the producer states it should flower 8 weeks same as bubblegummer.. Well heres the history of plants. They vegged for ca. 2months becouse at age of 1 they were as big as should be after week or less.. Problem with starting soil i think. Then i transplanted to this royalty mix and they starrted to grow nicely. Before changing to 12 hours grapes showed preflowers about week before and were first flowering. Now bubbles have much bigger buds and still growing and needs about 2 or 3weeks to finish. For grapes i would say week or little more as many trichs are cloudy. I dont like to leave it to amber too much. Well since transplanting and problems one bubblegummer was defected and have strange leaves and growth but i left it. Now this one has buds like skunk and looks the best and very compact but is ready to cut. Amber trichs are seen-i dont know why but its great. Good i didnt throw it.. Well grapes didnt have early shock i think but they stopped to fatten about 2weeks ago or more. I have to add new replay. I am on phone and its freezing so ill continue in next replay.

No, from the day you flip to 12/12.

Some spaces in this paragraph would make it easier to read

Interested to see the pics when you have time.

i have big troubles posting on phone.. So i will come back after work.. If this one will be posted few infos.. Pots 30ltr-ca. 7.5gallons, temps 18 to 19 at night..not much more when lights are on..and there is no light leaks in the room..i dont have a ph meter to test it..hard to get one where i live..

If your pH isn't correct, your plants may not be getting fed properly.

When your pH is off, certain nutrients can become unavailable to the plant, depending upon whether the pH is too low, or too high.

This will lead to a decreased yield.

Obviously without pictures or more information, my diagnosis is incomplete at best, totally wrong at worst.

i will be home at about 4 hours and soon after i will take photos and post.. I know that ph can lock nutes..i would have one if i could get one from our country..there is one on grow shop but i have no idea if that one can measure soil ph.. With ph i am total noob sorry..i will later give you link to tell if it will be good..for next grow..oh what i forgot..i had or i think still have fungus gnats..not sure but i believe its that type of fly compared what i found online about it..they are in soil..but if they would make harm and eat roots and stop budding why would indica grow nicely? They are everywhere all pots i think..but yesterday it seemed like there is much less of them..

Hi,
So i came home now and i can give you some pics, but i don't have a good camera for shooting at hps light If needed i will make new pics with some normal light.

DSCN1362 - the one on the right which looks tallest is just a clone, which didnt have much light, i just put it closer to light yesterday. About this one i don't really care much..

1381 and 1379 - That are the grapefruits, so small.. And there is hardly any bigger bud looking at thickness.. 1381 is from another plant which has a little bigger buds but hard to say really once as big as another grape.. But if at least both would have that big buds..

1376 Is the one i said was defected and looks pretty much like skunk and is already ready to cut, i have already cut of few buds yesterday.. 1359 to better see its defectivity but is still hard to see from pics

1372 is another shot of grapefruit with smallest buds.. So is 1366

1360 is the bubble gummer which still needs time.

1368 grapes from above..

The first pic 1362, in the middle one that has pretty big bud is another bubblegummer, which i seeded about a month later or even more, when i thought the defected one wont make anything ..With this one i didn't use any training.

Oh..I almost forgot, the one i just told that is in the middle in first pic. I noticed that it has yellowed fan leaves on top(They started to yellow from edges to inside) and few lower bud leaves, would that be heat stress? The bud leaves on very top doesnt look really affected so aren't other buds, just main cola. If i put my hand there at top it isnt burning anyway but this one is right under light all the time but still about 30cm now, before i had it somewhere between 20-30cm away.. I noticed it about week ago, but how long is it that way i don't know becouse when HPS is on, i can't see it, even on grapes as i mentioned the tips of leaves from buds are brown it is hardly seen with hps and probably you wont notice it from pics.

i see nothing wrong. with what you have. those are going to dry out the same size. they look nice to me.

yountook off all the fan leaves.
or did they yellow. your alittel small but not to much.

How do you mean they are going to dry the same size? Isnt there suppose to be 80% of water? For indicas as i have little experiences already, buds has dropped their size after drying for at least a half they were big before..
I didn't take all fan leaves off, but yes, as they yellow, i took them away, sometimes i took some that needed to go away becouse of blocking light.. And everyday some of leaves get yellower and i take them off then. Few per plant. Isnt that normal for near harvest time??? And about grapes small buds, they look very light and not compact..
