Setup : 60*90*140cm (2*3 x 4.5ft) tent (two compartments, one 60 x 60 cm (2 x 2 ft ), the small one is 30 x 60 cm ( 1 x 2 ft ), the wall between the two compartments beeing removable ). -> counting 20cm (8inch) distance to lamp minimum the plant can be 70cm high (2.3ft). 60cm is prefered (2ft) 19 L (5 Gal) DWC bucket with 200Lph air pump ( no automatic top feeding system ) 1000W kingled aliexpress lamp ( which is actually 250W @ the wall according to sheet spec ). carbon filter and a 40W Fan extractor ( air extraction is 320m/h ) EDIT From D5W5 : i do have the real consumption of the setup : lamp (veg mode) : 120W lamp (flower mode) : 85W lamp (both mode) : 200W Extraction + airpump : 85W i'm only using both mode on the lamp for the week 6, as this is the transitioning point veg/flower, and i guess the plant could use both spectrum ========================================== One seedling is NL, other purple bud, both from White Label (auto). one ended up dying ( next week ), and if i remember well, i kept the purple bud. more on this next week. PS : i'm righting this diairy while i'm currently on end of week 5 ================================================ Day 1 ( picture #7 ) : i don't believe i can consider them sprouted, the seed is still attached to the main root. i believe i didn't put the seed deep enough. Watering with tap water ( 7ph ), solution is ready in the bucket at 5.8ph Day 3 ( pictures #8-9 ) : it officially sprouted, the seed is still attached, which is a problem, as we can already see the first node ( #9 ). I removed the seed with a bit of saliva, trying not to hurt the plant, seems to work. Day 5 (pictures #10-13) : the plant look a bit whitish, i'm wondering if it's not lightburn ( EDIT from week 2 : i think it's actually due to overwatering & limescale from my very hard water and humidifier ) Note : i'm really struggling with the heat of the tent. i don't know if the lamp heat too much, or the extractor doesn't extract as much as it should. the humidifier help lowering the temp, without it, it can go as high as 33-35° C ( 90-95°F )

@lightmooner you will need to switch to your Bloom mix once the stretch is slowed down and the the little budlets are starting to develop Looking at your plants the stretch is happening now so prepare to switch over about the end of next week. If you continue feeding the veg nutes too long your plant may develop a nitrogen toxcicity and also may become potassium and phosphorus deficient.

i think i switched to flowering nutes too late, now i have a nitrogen toxicity. i'm running at 1/3 the concentration of flowering nutes, is it the right way to go? can it comes from the PH down from GHE, as it contain nitrogen ?

Yes you have a pretty deep Nitrogen toxicity , last time I had that issue it took 1 month after 12/12 switch to see the 1st pistols so it's an incredibly efficient grow slower. What to do is to cut the N ( not the PH down as it's not containing enough N to feed the issue ) I would try to make a test : keep the same EC/Ppm amount but increase the PK dosage while decreasing the rest . It could force the plant to use the Nitrogen she has stocked in her system.

I think you should keep using veg nutes for a while. At least until you see some actual buds forming. I just had to add some veg nutes for a couple of days and I am about 40 days into flower. I have large buds all over but they still needed some N. Good luck on your first grow.

@MountainBudz, thanks so much for your reaction ! i agree, i think i can still keep her under veg for 10-15 days ( from pictures #9-10)

@@Mo0oD, it's one of those "you wont know until you grow" type of things, for autos the results will be ..., fast photos and fem photos you can keep in veg as much as you need , so actually it wont stall it will sort of hurt until the end , i see what you mean about compatibility and using little, but it's just not working out as you can see, i think the .8s are too much and if they're synergistic means that you'll need less of each, either way that downwards curling needs to be fixed with a chelation agent though gotta stabilise your soil matrix and reach the root zone 😅

@CRiSPrGrow, thanks for your reaction so much, but i'm quite unsure it's due to the root, they really looked fine, and i assume i used too much hydroguard ( high concentration ). But it's a different bacteria than rhizo, and according to my research and post on forums, they're compatible. ( i might be 100% wrong, just saying what i found out on internet ). the really really weird part, is that i get 1450ppm in the bucket, while i have 800ppm on my topping water, which should be the same concentration, i think i did a huge miscalculation when switching nutes, and i'm getting ready to completely replace the res. Nonetheless, what should i expect out of my plant ? is it going to stall for few weeks, and i'll get around the same yield, but later on ? (instead of harvest @ 12th week, as example, due to my toxicity, the plant would only be ready at week 15), or will it be ready at week 12 with a much lower yield ? ( i'm just giving the number of week as example, i realise the plant choose when it's ready, not me). how long would it stall for, knowing that it's an autoflower ? thanks again :D
