Are only the leaves towards the top yellowing?

cannabisgirl123 · Jan 11, 2016

Yes sir .. only the top.. some of the bottom too but its not something diffrent from what i know

Watering and feeding schedule's? Rt/rh? Ph of soil? Type of lights and distance from canopy? The more info u give the more help you will get.

Just as a guess i will say iron and zink deficiency

cannabisgirl123 · Jan 11, 2016

I watering twice every week with hesi nutrions .. and i add minimum of bloomblastic by atami
The ph is always 6.3-6.5
600w hps the topest cola is like 16cm from the light but i did the hand test and not feelin something too hot .. 0

16cm??? That's a little over 6 inches.. I have a 600how air cooled hood and I am over 15" away. I would back them off regardless..imho

Not really, how much u using twice a week? I like to feed once a week alternating with water and micros

cannabisgirl123 · Jan 11, 2016

I water untill i see some serioes amount of water draw from the bottom..

SPLFreak808 · Jan 11, 2016

Possibly P-k toxicity. That shit locks out secondaries and trace nutes like a motherfucker.

tropicalcannabispatient · Jan 11, 2016

Yea thats why i say iron and zink because they get locked out with pk excess and the yellowing in those deficiencies start on tops new grow, also pk cause mag and cal lockout

cannabisgirl123 · Jan 11, 2016

Any solution?

Purpsmagurps · Jan 11, 2016

ph'd water

Purpsmagurps · Jan 11, 2016

wait a couple waterings before you give it any more pk. then feed every other watering.
this is if your ph is on point, if its PH causing that just get it to the right range and it will stop.

You say ur ph is in the 6.3-6.5 right? then like i say since the beginning when i did ma guess its a salt build up locking out micros for feeding twice a week, or a pk excess locking out same micros zink and iron this def start on tops getting yellow, also locks out calcium and magnesium, but it looks more like zink and iron def

tropicalcannabispatient · Jan 11, 2016

How many gallons of soil the plants are in? Do u have micro nuts?

intenseneal · Jan 11, 2016

Yeah fist get that ph down a little. I shoot for 6.0 in soil, to me it appears to be a sweet spot for all the micro and macr nutes to be absorbed by the roots. Chech the ph if your run off water as well and see what that is. If the oh if your run off is higher the you have a salt build up and a lock out issue. I would not rule out a nitrogen deficiency, im not familiar with the nutes you are use so i do t know how much N you are feeding.

I will say n is out of the picture since n starts from bottom, and she has yellowing on tops
