Leaves Dying

Looks like PH fluctuations. Check your runoff ph and ppms and then you'll have an idead where u at. Best of luck 👍

Thx alot for your answers it is definitely helping ! And yes I understand I have no diary on this grow so it is difficult to say exactly what is wrong. AsNoriu you are right I did give them alot of sugers in the form of Molasses and the water I use is very hard water. I also think my PH was dropped to fast. GrowingGrannie thx will definitely give them a good flush tonight and see what happens. I did flush them a few days ago but not with that much water. But will definitely do it with more water now. Thx also to Organoman

Plenty, but without a diary and being able to see what you have or have not been doing, it is hard to give specific advice. If you combine the answers from growing grannie and asnoriu, you may find some clues. I tend to agree with AsNoriu though, start again, burnt plants like these seldom produce buds worth anything. Asking questions a week ot two ago, when the problems first started, may have meant recovery would have been fairly simple, but now that this has progressed so far.............

There's no diary associated with this grow so you're really asking us to advise you blindly... There's pretty much no question, however, that you've got some nute lockout going on and an off-the-charts nitrogen toxicity. If you want to have any chance of saving your grow, do not pass GO, do not collect 0 - give them a pH'd flush NOW... If you are unfamiliar with flushing, this means that you need to water each plant with 3x the amount of water as the pot size so if you're growing in a 3 gallon container, give it 9 gallons of water that has a pH of 6.0-6.5... this will flush all the salts and excess nutrients out of the soil and get them back into a good zone. When all is dried out, you can feed them again but do NOT give them any of your Bio grow... grow nutes have way too much nitrogen for plants that are in flower... I would start checking the pH of your runoff every time you water/feed for at least a little while to make sure it's in a good range as well.... As for your lights, they are far too dim for flowering and have not contributed to this problem at all, imho... so get them back up to where they should be for flowering... buds need all the light they can get! Your plants look like they are warriors and while your harvest may have suffered some, you'll still be able to get something out of this grow. There's a reason this stuff is called "weed" - they can take a lot of abuse and some of them refuse to die so good luck!

pH issues, dechlorination and pH control is key. Plants grow without nutes in soil. From my perspective - I would start again, I failed to recover so burned plants like in your 3rd photo. My wild guess you added some sugars or downed pH to insane 3.0 or so ... I tried doing flushes, tried to nurse such plants, most of time - lost fight and pitty harvest. Never had bacterial feed at that time,maybe something like BioSys by EcoThrive would save them. Increasing pot size and normalising fauna in pot - the way too.... Good luck.
