So basically on a few of my plants they have these weird spots on them on the old growth...nothing on any of the newer stuff on the top but on just some of the leaves toward the bottom i thought it would just be from them not getting any light (plants grew a little 2 tall this time) but i'd like to hear from you guys

Grown in ocean forest only nutes i've given is cal/mag and a very small amount of fox farm grow big

other than that all water

Temp about 68-74 with 50-60 RH

That looks like phosphorous deficiency. The grow big is well balanced so I imagine you've just underfed them. The fact that its on the older leaves and you have been feeding plenty of Ca means that it is most likely a macronutirent problem. Try re-potting (if needed) and giving them 1.5x strength grow big until corrected.

yea i haven't given them grow big in a while, not sure why i would need to repot but i'm going to give it to them on my next water
 
How old are the plants? As Racerboy said a pic would be very helpful.

1 month and 16 days since i took them out of the cloner and like i said its only on a few leaves on the lower growth what would a picture tell you? i will post 1 in the thread in the morning
 
Its not rootbound. Its probably hungry being almost 2 months old and you've only fed it a little, or you splashed nutrient water on the lower leaves when you watered it. Ill look at the full picture when you post it, but for now that's my best guess my friend. Good Luck

Your plants look good to me....just a bit stretched alright....I recommend topping your plants or they will be too big after the stretch in flower.....if you flower them that height your lower bud will be b grade at best....just my thought
 
yea they stretched alot this time had someone watch them for me for a week when my mother got sick and he didn't do a good job watching em =\ i think you are 100% correct tho
