First grow...multiple issues identified

I need some help here guys. I'm on day 73 since sprout, day 41 since 12/12 switch, and day 33 since showing of sex.


yellowing of bottom leaves, purple "rash" shown

curling up of leaf tips, browning of very tip

deep red/purple rash on leaf

any guesses guys? it's been flawless so far. these problems are presenting mainly on leaves that do not have bud.

So they been 12/12 for 41 days total. What is the strain your growing? What is the finishing time for those plants. My plants changed color mostly all fan leaves will change color when at lower and cooler temps. I had my tent temps run low in the 50's during lights off period and my Bubba Kush turned completely purple and my Chocolope turned reddish brown and yellow. If your dialed in on your plants then its just your plant maturing in age. Now some of the tips of your leaves do look alittle crispy in Pic#3 thats no big deal if thats the only one but as long as your new growth in the buds are not crispy its fine. Thats my opinion. But just keep an eye out for any other leave tips getting crispy cause that could be a pH problem or even a start of a lockout or something. Hope that helps, look in my signature of my plants in the 1st grow and look at my chocolope and bubba kush plants.

Peace

All I'm doing is running Lucas formula and topping off with water and nutes as necessary. I'm ebb&flow...read somewhere that with the nute formula I'm using, no changing of resevoir completely was needed. Should I be flushing them? If so how often? Thanks for your prompt response

@BKB thank you for your response..this is NL #5 with flowering of 7-9 wks

I am growing in soil but I flush my plant every time I feed it nutes. I recognized the leaves that are crispy cause I had the same problem and my pH and soil had a build up and my plant had a Nute Lockout. I also flush my soil with water pH'd @ 5.8 and then coat the soil with Nute mix pH'd @ 6.5 for maximum Nute Uptake. I have no expierence at all with the ebb n flow. I would highly recommend you flush your plants and give her a fresh dosage of nutes she can handle. I am a huge fan of NL#5. Hands down my fav strain. Although I have yet to grow it, but I will when ever I can get my hand on some seeds or money for seeds. I have a bunch of NL crosses that are sweet too. Flush that baby and watch her growth even more. I am sub'd in your thread so I will be around. Good luck and let me know if there is anything else I can help with. I am learning and new at this but I will help at any cause.

Peace
