Yellowing Leafs

Hello I am just wondering if high ph could cause yellowing of leafs. It was 7.3 for a long time I think. I didnt have a meter and when I checked my tap water it was 7.0. So I adjusted it to 6.5. I am just wondering will the leafs stay that color will they come back? Im growing in soil, FFOF into the 5th week under a t5 with a few 23watt cfls.

No I don't think ph is the issue. Are you feeding nutes??? Just looks like they are running out of nitrogen. I have heard that FFOF has enough nutrients to support the plant for only 4 weeks. Just a thought

That looks Nitrogen Def. The plant does not need as much N during the flower period so to some extent that is normal (that's why bloom nutes have a low N value also too much N will cause late flowering) but it looks like you have just a bit more of a N def than would normal. I don't think its a catastrophic issue because the tops look fine but if you could add a little bit more N to your nutrient schedule you should be fine.

I have been feeding them Tiger Bloom with molasses. I water once a week with the tiger bloom. 2 tsp per gallon. It says I could add 3tsp.

By eliminating all the variables you can then pin point whats going on. You will lose the yellow leaves but the others should stay and get better. If you have a stable nutrient which it sounds like you do then eliminate the other voo doo stuff. My thought would be to flush completely then start back on the next watering with your normal 2tsp watering then up it the next time to see if you have any changes. I would tell you to foliar spray but you are way into flower and it could cause mold. Some people swear by molasses I am just trying to eliminate variables right now.

See what I mean? Molasses users are the most emphatic growers about that topic than anyone on the board. Hey that is what opinions are for.

i dont use molasses lol when did i mention that i use molasses?? lol for your information i have experience with molasses and have used it plenty of times but now i use carbo load so there is no need for me to add molasses..plants need carbs bro, read up before you give input.

i dont think the molasses is the prob, molasses is 15% of GeneralHydroponics flouranecter(like cali i use to use it b4 i started buying carbo supplements)... but i have been using FF for years, and the tigerbloom does not have enough N in it, i like to add 1/2 - 1 tsp. GrowBig, that seems to help stop they yellowing, peace bra

So im guessing thats why they say to use them both? lol I dont have the money, but what if I use just a tad bit more tiger bloom? I am using 2 tsp what if I used 3 maybe 4 what will happen? Will it burn them if I use 4 tsp? I would take a pic of the other plant but its dark there now. The other plant is having kinda the same deal but only a few pedals on a leaf are turning like a tiger stripe yellow with brown spots? And again just like b4 the water was 7.0, and i just keep feeding it with that water for weeks. Until I got the meter, Now the ph is sitting at 6.5. The other plant is 2 weeks behind this one.

if you cant afford the GrowBig i guess the only thing you can do is bump up the nutes no?

go buy some fish emulsion, it's hella cheap..that should help get your Nitrogen levels up a little bit..u dont wanna add to much though in flower..i'd give it a full dose once then wait a couple weeks and maybe do it again.
