Young plants, Yellow Splotches, warped leaves

Hey so started some plants overall they are looking well but got some oddities. One is the worse with big yellow splotches throughout the whole plant. One or two of the others are rather small bushy and kinda warped leaves. Recently some of the healthier ones have look more yellowish and droopy. :/

They are under 280w of light but its 1-2 feet away. In coco being fed every time.

Through the splotchy thought i might be getting PH lockout from it being a tad too high (using tap water).

Thoughts?

Coco likes pH of 5.8 I think..More like hydro.

Yah thats what i was thinking, but i dont have a PH meter. Guess i kinda need one huH? I was going to put a spoonful of vinegar in my next gallon of nutes/water to lower the ph a bit.

You can get pH paper kit for anout$5? atleast get an idea where you water is.

any idea how much ph meteres are and where i might find one for a reasonable price ( i assume pool stores and maybe walmart carry them?)

If it was only 10 or 15 more than that would be the better buy no?

they also need to be put into bigger pots, once they get rootbound in small cups like that its only a matter of time before they die and/or stop growing.

hello,i also have that problem my ph is 5-6 and i still have yellow leaves coming(even happens with clones!!)

Some cheap meters work..I have a Milwakee as back up. Gotta calibrate it a fair amount and store in solution..Check amazon.

I was hoping for them to show signs of sex before I transplanted, is this a bad idea?

i doubt they'll show sex at that age... you should transplant really or growth will stop. also get a ph meter and use vinegar/lemon as the cheap option of bringing it down

i would transplant asap, the reason they kjinda stopped growing all together is because of the rootbound, i mean they will still grow, but it will be really slow and just a pain in the ass ya know bro
