OK now because I am a new grower and have never really grown anything in my life up until this point I did a lot of research and watched so many youtube videos, growing video, read many pages of forums and asked questions there too, read papers on PAR, Temps, humidity, deficiencies, PPM's, PH, VPD's ... which was pretty good and helped me a lot, but there is no substitute for experience.
Temps have been high in Australia at the moment so they are pushing the 29 degrees celcius (84.2 F) mark sometimes during the day I have tried to combat this but freezing 2L bottles of water and putting them in front of my fans which seem to be going well I have been using a VPD chart though to make sure my humidity levels and heat are optimal.
Now as we can see those leaves are very green .. and that is because I overfed them ... I Started to get a nitrogen deficiency on the plants on the right, well I thought it was nitrogen deficiency looking back now it was probably PH lockout/issue due to high salt buildup because I was listening to people tell me to let my coco dry out ... so because I was feeding them a quarter strength, I was like well, they must need a half-strength, so I fed them half strength 6/9 h3ad formula nutes to try and fix the problem, which came upto like 1000ppm and because I'm a noob I just used it and watered them lol
then I was watching a YouTuber who said to run 3ml calmag 4ml of micro and 8 ml of bloom from week 3 till flowering... so I did that to the next watering came up to like 1000+ ppm again and once again because I'm a noob I feed them with this again ...
So then as of course would happen all the leaves started clawing and turning dark green. I knew what this was immediately as I had read a bunch on deficiencies and toxicity clear case of nitrogen toxicity ... so I double flushed my pots with 500 PPM nutes and they are now on the road to recovery I am now using a PPM chart from a fluence bioengineering paper I read and am now feeding them at 1.3 ec (650 ppm) at a ratio of 2/3.78 ... I might even go a bit lower
Ill start LST in the next few days as the tops have come through nicely.
This is the star of the show at the moment bushing up and getting large, only problems have been from overfeeding ie. user error. I hope she doesn't turn out male .. such a nice plant
Same strain as the first pic, she is growing pretty nicely as well new tops have come through nicely and got some good lower growth after she had been topped.
This one (middle, same strain as first 2 ) started off as the runt and is still shorter than the others and is still in a smaller pot as I don't have the room for another larger pot
she is growing really well now and has shown me that coco can definitely support plants in smaller pots quite well, something I will use to my advantage next grow
This is a different strain to the previous 3 ... these guys started with the bottom leaves yellowing which was either nitro deficiency or PH lockout from me not knowing what the fuck I was doing
. You can see my bad watering in the plant growth progression itself, with the yellowing bottom leaves, the super dark green leaves in the middle and normal colored leaves coming from the top now that I think I have the nutes dialed in .. she is telling the story of my grow haha
Now this one has been the worse affected out of all my gal's .. I think I was not watering this plant properly which caused big ph and deficiency issues ... she is starting to bounce back a little now ... but I have seriously considered pulling her out for the other plant in the middle ... still considering it now ... but it so hard to just kill them after you have put so much effort into them haha.
