2nd grow I'll write shit down and go by the books, that's for sure lol, now I didn't learn anything

"guessed the ph " -- don't do that... lol... it's better not to pH at all than to do it blindly. 4mL of a mild 5% acetic acid would drop your pH to unsafe levels in many contexts of typical tap pH+nutes mixed or not, for example. because pH could be off, you may not have any nute issue whatoever.. it depends if it was lockout from pH issues or not. definitely gotta work out your pH and feed in a more resolved way... it's not just adding this or that and letting it go... it's about providing what the plant uses over time... you slowling refine your mix based on observing plant, but you may need to get a better starting point to more easily do that without conflicting info (ph issues will fool you as to what symptoms you see vs what is actualyl going on) i'd ensure pH is in order, and pay more attention to what you feed so you can make an informed adjustment based on observances. get a leaf symptom chart. learn difference between mobil / immobile nutrients. learn difference bewtweed interveinal chlorosis and other forms of leaves paling... if pH is solid and other things are fine, you can actually diagnose the plant very easily... when pH is off or nute ratios are out of whack, any and all symptoms might show and have nothing to do with the normal cause of such visible issues. (e.g. you see Mg deficiency, but caused by high K, you'll see a "Mg-def" symptom from lockout but it will have nothing to do with phyiscal presence of Mg.) So, when you got a good grasp of it, the answers are more obvious and more easily fixed. it's not mystical. it's finite and we can resolve the change over time resulting from multiple relativistic factors, if we put in an iota of effort to understand it better..

Looks like you got some light stress some heat issues and nutrients issues too, I’ve seen a plant turn blonde throughout its whole life and come back green at the last 2 weeks of flower without any problems. Check your climate conditions and that one in the back needs something

They don’t look too bad Growmie, with regards to the PH, try going lower than your usual and see what the runoff is, it will typically be higher, but should be adjustable with you adding a low enough ph solution. 7 is not terrible either, not great, but could be a lot worse. 3 weeks left, You could also just try to ride it out… but a PH pen in the future would do wonders for your quality and yield! 👊❤️🇨🇦😎

Well, you'll get a harvest, of that there is no doubt... will it be a good one? Only time will tell.... since you didn't write anything down and flew by the seat of your pants, we don't know what you've done or not done and have no way of advising you. I'm HOPING the color is just a result of the lighting.. I've actually never SEEN plants that look white... My suggestion here is that, if you want a decent harvest after all your time and money, you get a little bit more serious about your efforts. Glad you're not building a house to live in! Good luck.
