Ok I was thinking it may be that I live were the temps are around the 100 degree mark just about every day... And end of June beginning of July after having 2 weeks of almost full sun I bought a plant shade that blocks 35% of the light out ... And after that is when I started noticing the yellowing of the leaves.. also last week i cleaned out the bottom of the plants and cut away all the growth that was not going to amount to much and that added air flow through the plants(they were getting a bit bushy). since that time (4-5 days) my plants stretched over a foot tall they are very happy over all and I just want to stay on point during the first of flowering... Thank you @Emilya if I notice anything worsening I will prob reach out to u again if that is ok also if you could give me your opinion on another plant I am having issues with from another post that would be awesome What nutrient deficiency is this?
This yellowing from the bottom up appears to be nutritional... this plant needs more nitrogeni have a much worse problem than you, @Treeibus! Your plants look much better than mine. I can’t figure these out!!
Biggest plants I’ve ever grown (a few of them are very tall). I keep wondering if I am just pussy footing around on the nutes and not going bold.
I was giving them Humboldt Secret nutes at their full recommended strength but I think I got lockout due to high soil pH (I measured and it was 7.3!). Or just too many salts.
I also found my water pH is high and I had been watering them straight with the hose and a lot at that as we had the same high heat and they were drying out almost daily!!
@Emilya do you mind diagnosing mine, too, with same yellowing issue as asked originally?
That depends... I have seen plants start to green back up just hours after watering. Anyone telling you to go light on nutes when you are running outside, doesn't know what they are talking about. The sun is bright, and you have large plants there. There is no logical reason not to be feeding them the max, because most nutes are designed around plant response at 1000w of light... you have a bit more than that.
There's leaf miner damage on the leaves in the first 4 pics. You may want to research how to deal with those. I've never had them on anything that wasn't ornamental, so I never got around to it.My plants are in the secound week of flower I Grow outside and I have noticed yellowing of the bottom leaves and now starting on the middle of the plant and it seems to have gotten worse very fast ...I was wondering If anyone can help... (mabey @Emilya perhaps I know she is a guru when it comes to diagnosing plants)and you guys are the best growers out there any help would be great

I was thinking i am doing the same thing only difference is my plants are in ground not in pots. I noticed from ur pic that u don't have a plant shade..100+ temp = stressed plants so i would highly recommend getting a plant shade to cover them during extreme heat for a few hrs a day or else ur plants will die. the plant shade has made all the diff in the happiness of my plants hope this helps ... that being said ur plants look good bud I think if u get ur ph fixed and get a shade for ur girls u will be fine hope this helps
ya the leaf minors are a constant issue lol i just pull the leaves that are affected and go about picking the lafehoppers that are a bigger issue for me atm LOL
I was mistaken... I really dont see any deficiencies... just a little bit of bug damage.
Yeah, I have leafhoppers every year. I tried insecticidal soap, but you have to hit them directly and those little buggers are fast. Now I just squish them when I can.
Cool.... and Do u think the curled new growth is from heat ?
Ya thats what I do with them now ... I have also found that if u spray them with a squirt of dish soap water( i use dawn) they freeze in place and u can pick them off real easy
