Ok I'll keep this in mind! Do you think Tiger Bloom may have caused this? If I had to guess it looks like a nutrient block or deficiency but it's hard to determine which. If it helps- I've used the trio Fox Farm combo (Tiger Bloom, Big Bloom, and Liquid Plant Food) since the beginning of this grow (until last month) in Fox Farm Ocean Forest soil. I didn't supplement fertilizer until they showed signs of needing them, of course. Maybe I should put Big Bloom back in the mixture? Additionally, yes, it should be a bit warmer during the day. Working on a solution for this. I appreciate your input!Tiger Bloom is not very good, it can cause problems. Also, your daytime temps could be higher.
Hmm... Alright, what fert composition do you suggest I use at this point? Or should I try just normal watering? Before anything else, though, I'll flush them. Haven't flushed since changing their pots around the start of veg BUT every time I feed them a good amount of runoff flows through so I told myself it wasn't necessary. Maybe that might be a factor as well...I've used the Fox Farm trio as well. The Grow Big is ok for veg (I use it for my vegetable garden and houseplants now). Big Bloom is great, but crazy overpriced. Tiger Bloom is a mess, I had plants looking like yours once. I don't know what is wrong with the formulation, but it causes lockouts. I used it at half strength and the plants didn't respond well.
7 might be a little high, but I think it has a pH lock….It kinda looks like zinc deficiency? I would defer to those more experienced though. If your soil pH has dropped due to the 6ph water you may have locked out calcium also. Need to get soil pH up to 6.8-7
your run-off ppm will never fall below 1,000 ppm if your using organic soil such as Fox Farm Ocean Forest. The soil may or may or not buffer pH, depending on how it was initially pH balanced. As salts build up in the soil (for many diverse reasons; but if you don't do10% run-off, the soil will naturally decrease in pH over time).Looks like nute burn and chronic slight over-watering to me, based on the burned tips and edges, and the pronounced texture on the leaves. Water when your pots are light, not on a schedule. When you do, water to 10% run-off. Check the ppms of the run-off of your next watering. I aim for 1000 ppms in week 6 of flower, and then I don't feed again, assuming an 8-week flower. Soil buffers pH, so I don't micro-manage it. Others will disagree. As long as my input is between 5.0 and 7.0, the soil does the rest. There's no fixing the burned leaves. Next run, water only when the pots are light and feed only when the run-off ppms fall below 1,000.
I flower in FFOF and this has not been my experience. Lots of ways to grow. Good grows to all.your run-off ppm will never fall below 1,000 ppm if your using organic soil such as Fox Farm Ocean Forest.

the Interveinal swelling and burnt edges scream overwatering bud. Let me guess, your brain was telling you too fix problems you think you got, so you kept adding water mixed with xyz to correct right, probably been trying something new every day? You gotta give a plant some time to recover. Don’t water again until your pot is lite when you pick it up. Also the leaves will never repair themselves.Also what should I do with the affected fan leaves? Will they revert to their green shade if I fix the problem? My brain is telling me to try a few things but keep in mind they're already over 4 weeks into flower... Unsure how much benefit or harm will come of removing the damaged ones. Sure it exposes the bud sites below but will they maintain enough water and nutrients to keep the plant healthy? So many questions... This is my first grow if it wasn't painfully obvious lol
No I've been using the same concentration ratio since February (2 tsp Tiger Bloom, 2 tsp Big Bloom, balanced to roughly 6 pH) and only water once every 4-5 days when the soil is dry enough I can stick my entire index finger in and not feel moisture. They each get half a gallon and a good amount runs off despite slowly, incrementally feeding that half gallon. From what everyone has described I'm fairly sure it's a nutrient lock due to soil pH (which I literally have never measured) so my next course of action is to test the soil pH as well as runoff pH and PPM. I do not have the tools to measure this so I just ordered some which will arrive tomorrow, at which point I'll test the initial runoff before giving them a good, overdue flushthe Interveinal swelling and burnt edges scream overwatering bud.

Will keep this in mind when I measure everything tomorrow.

You're welcome. I hope it helps. Looks like you're going to get a yield from your first grow. Congratulations! Here's something to consider for your next run. Growing in soil, cannabis craves dry days between waterings, so all its roots get plenty of air. You might be surprised how much water is still in your pots when you're watering. Gouging around with your finger gives you an idea of how wet your soil is as far as your finger reaches. But gravity pulls water to the bottom of your pots, so the bottom of your root ball will be wet longer than the top. The only way to reliably know how much water is still in your pot is by weight. Some people use a scale. A lot of people do it by feel. Others wait to water until they see a touch of droop in the lower leaves, and then water a day earlier next time. When you chop this current grow, check your root ball to see if your roots are healthy, meaning white and fuzzy with root hairs. If not, consider watering by weight.Will keep this in mind when I measure everything tomorrow. Thank you very much!
