I am running a DWC setup in a 5 gallon bucket under leds. My plant is 7 weeks old and I change the reservoir weekly and start with the PH around 6. Several times recently the ph has dropped to the low 4s. The plant is taking up a lot of water and nutrient level is around 1000ppm using vegetative nutrient mixture.. Other than the ph drop the plant seems quite healthy.

Thanks, I'll try not to worry
I've got a lot of effort tied up in that plant. Does this mean I should change over from a vegetative to bloom mixture in the reservoir or wait a while longer.

yea Buddy I would switch for sure... Ive been on bloom for weeks now ... but I did swap to early ,either way no worries.Im sure any stretch will stop soon & it will be weight gaining time:booya:Good luck
Okay, I switched to 80/20 bloom/veg mix this morning and if the plant still look happy next week I will go 100% bloom. Do you have any recommendations on PPM? I have been gradually raising it and am now around 1200 where I thought I would keep it.
Anyway, thanks again for your help.

Well kind of depends ... can you throw up any pics ?. Other than the PH drop ,are you happy so far ?. 1200 could well be ok for a 7 week mazar & I must be around there as well .If you test ppm a lot & It's rising then you could just top off with water to bring it down until it settles ... or if you see tip burn ect .If she looks happy & the EC stays relatively stable through the week ,you should be good .
Any info on all your set ups good bud ,nutes ,lights ect. 1200ppm may be to much for a small plant ,or one with issues ?. Sounds like you have things under control though... like you said Im not going much higher unless I notice the ppm drop a lot in the res & then I guess it goes up 100 or so :smokebuds:Thats how you can tell if shes hungry or overfed like

Here's some photos. I am using a Blackstar 270 led. The plant is about 14 inches tall and at least that wide. Also, I have bent it to keep it low and bushy.

This is an excellent explanation on the life cycle of an autoflower...and when to switch to bloom nutes and lites...
