yellow leaves - need advice [pics]

[handbanana]

-indoor

sunshine mix #4 w/worm castings & perlite

mid flower

nuts= combination of foxfarm & h&g

water every 3-4 days

1000w hortilux - glass/vented 30" from glass

day temp=74-77 nite temp 66-70-%

humidity 60-75%

12/12 schedule

vented like a champ




after thinking it was nitrogen deficiency i hit all plants hard with nutrients

some have begun to darken up from lime color and are looking good.

others ...not so good- have turned brighter lime and started to burn.


leaf pictures are from the very few leaves that are burned that bad ....mostly they are bright lime w/ a little burning.

one thing i am dealing with is the possibility of plants being too big for the pots. they vegd to long and are possibly root bound.

seems to be confined to a couple strains and not others. only i cant tell you which ones are which at this point sorry !

all my homies are out of town -so i turn to you fine folk of the weednerd sect.


any thoughts suggestions advice


wil be greatly appreciated - thanx

If they arent responding to ferts or worse burning


complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph

Looks like Mg but how far into flr are you? Have you ever tried epson salts 1/8 tsp per gal, grind up first so easily mixed. Don't forget to ph water first! What do for water? How do you prep your water/nutes? Remember if root feed does'nt fix in 3-4 days maybe lok-up,then try folier.

believe it or not it was a heat problem. my lights were not vented enough and were cookin some plants. sorted that out by going to a larger fan size.

other than that plants are healthy, with normal yellowing and leaf loss. soil ph is perfect . ladies are swelling...


thanks for your responces.

bestys!!!
