    Default Yellowing leaves HELP

    Hello, I have two plants of the bank fast buds, a glue gorilla and a pinneaple express, both in their second week of flowering. Unfortunately, the gorilla glue began in its first week of flowering to turn yellow the leaves of the bottom, which I assumed was normal because of the change from vegetation to flowering, however this week the vast majority of the large leaves are already yellow , While the high parts look good, and I do not know what that can be. The conditions are:

    Lights: HPS 400 watts with cooltube
    Carp: 3.15 x 3.15 inches
    Ventilation: 400 CFM extraction with passive intraccion.
    Pots: airpots 5 gallons
    Substrate: Top crop all mix (enough nutrient for 3 weeks)

    Temperature: 26-29 ° C
    Relative humidity: 40%


    Schedule nutrients: bio bizz from the third week, watering two liters of water from the key adjusting pH to 6.3 in vegetation and 6.5 - 6.6 in flowering.

    3 weeks: 1.5 ml grow per 1 liter
    4 weeks: 2 ml grow per 1 liter
    5 weeks: 2.5 ml grow, 1 ml bloom and 1 ml top per liter.

    Mid-week watering without nutrients with pH water adjusted to 6.5.

    A big mismatch that I had was to leave without water for 4 days, thinking of a possible overwatering. The photos correspond to the morning of today, I hope they can help me.

    Looks hungry to me, what are your levels of feeding?

    This week feed them with 2.5 ml of bio grow (npk 4-3-6), 1ml bloom (npk 1-2-2) and top max (npk 0,1- 0,01- 0,1) per liter , And yesterday only water adjusted to 6.5.

    That schedule seems to be fine, maybe try a feed feed water schedule. The lower leaves look like they have used up their supplies of nitrogen

    Just add an extra 1ml per litre of the grow in with the flowering schedule. This will help with the lower nitrogen levels. The worst affected leaves may start to recover, but will most likely die off.

    You should be fine, apart from the odd leaf, your plants look great. Keep up the good work.

    1 other thing... if your in soil... stop PHing your water...
    I find this a common mistake that ppl do. Soil and the microorganisms that live in it will sort any ph buffering out itself..
    Dont change the PH if you growing in soil...

    I would of used coco over soil if I'm honest mate but each to their own.

    I had similar problem with mine haze in autopots, what I found was the leaves that are brighter where just storing energy and and nutrients but eventually went away I wouldn't worry too much mine looked very similar, in week 7 now and look amazing just keep an eye on it for drooping or tips of leaves curling up.

    Are you hand watering or auto?

    If it's auto fed you won't of under fed it like my man said.
