these are my wonder women plants.. as you can see the bottom leaves have been turning yellow.. just wondering if anyone can get me in the right direction to fixing that?? they are just starting to flower.. temps are around 87 day and 83 night (high but have no choice) ph around 7.0 humidity is 70% (just ordered dehumidifier) on cfls 2700k for flowering, using some flowering type nutes....... any ideas?

your plants look very healthy. the bottom leaves will turn yellow and die naturally, they are called feeder leaves because the plant absorbs nutrients from them, but it is the first sign of a nitrogen deficiency. since you've only been using flowering nutes they are most likely low in nitrogen.

they actually started doing it when i was using my veg nute which nitrogen is 20... so im not sure it could be nitrogen.. i was thinking it could be ph.. also this pic is like 5 or 6 days old and a few leaves fell off and it looks to be traveling up to the next set of leaves.. thats why i am worried.. i will put an updated photo up tomorow once the lights go on

ph does sound a little high, dolomite lime works good for soil to stabilize ph levels. my bottom leaves always turn yellow after a few weeks of age though. what type of soil are you using? are you growing nirvana's wonder woman?

im using just a standard potting soil..no nutes in it.... yeah its nirvana's. what else can i use to get the ph down a little? im not sure what dolomite lime is.

Dolomite Lime: Derived from a naturally occurring limestone deposit, this granular fertilizer is a valuable source of calcium and magnesium and helps prevent soils from becoming acidic. It's cheap and it can be found at most hydro shops and online. vinegar or lemon juice also works as cheap ways to lower ph in soil.
