WOW thanks for the replies!!! My girl is dying before my eyes since taking the images a few hours ago the situation has gotten worse! I have more photos I took just now I will put them here. I had no real way to check the PH as the meter is just useless a new one is on the way but a few days a way and it may be to late for that. So I took a gamble and flushed again with a 5 PH water (used test kit to get it, but not sure how good that is either!) and dropped a little more soil in. I do not have larger pots right now and need to get them on line so again will take time I don't think she has? The pots are 10ltrs that's 2.6 gallons. The reason I went this way as I had just finished one test plant and it all went well in that pot got a good result. So I went and did 4 more to see how that would go and then this shit happened? Now it is a constant battle to save them! I am not real good at this just yet (obviously!) I am using Conifer Fertilizer Professional feed (2 caps in a gallon) and gave 100 mls of this solution a day morning and night for a week, they were going great. I have them in Canna Soil (Peat, pertilte, dolomite lime, mineral NPK fertilizer) Dry matter >30% Oganic matter >85% EC 1.0ms/cm PH water zone 6.0 Mineral NPK 12-4-24 1.5kg/m2. Had auto water feeders running so the soil stayed moist but not over wet, they work great. As they are autoflower I have the light on a 24/7 with the BLOOM setting on two Viperaspectra LED lights (450watts each). Heat has not been a issue as the room is a constant 22C max 26C. Air flow is good no hot pockets, the other three are much better it is just this one? It all started when the PH got high as I was unaware at the time of it creeping up until it went off the scale!!! Then in a mad rush I started flushing and now I really messed it up! The PH meter sucks! I think the soils is now at 5.5 PH judging from the wet test kit (drops in the water)? The lights are kept 18inches or more away at all times and they still stretch, so don't think it is light burn? I am hoping that my emergency flush will give it a chance, but we will see. I will put the updated images here. I really do appreciate your help guys!!!! I will look into getting the pots changed ASAP but it will not happen for this one unfortunately as it will take a few days and that may be more than she has? I want to run a 10 plant grow next time so I really need to understand what I am doing here! I will be using the
FOX FARM system in the future and have bought all the stuff I need for that and will follow their schedule to the letter next time, did not know about them until now. As I said previously I have had very good success until just now and it is the same seeds! Northern HIGH lights. The PH can cause the lack of nutrients which you mentioned here (thanks again!) but I am hoping that once the PH is steady it will grab what it needs without me messing with it and making it worse! The dam thing only has a week or two to go I would be devastated if it fails now after so long! The next run was going to be Auto Sour Melon Mass autoflower that's a cross of (Monster Mass, Sensi Star,
Big Bud Auto) So I am expecting good results! I just need to get my act together. And bigger pots!
