Whatcha been feeding them ? Magnesium deficiency is typical around week 3 of flower and epsom salts can be used to resolve. But ensure that the diagnosis is correct before you treat as other wise you could aggravate the situation.

If there in good soil and since they are already in very big bags i would say you should have had to add very little ferts to these. Peace

Kingrow1 is right. I dont normally feed for the entire vegging period and usually til a couple of weeks into flower.

How many times have you fed them and at what strength ?

There should be plenty of nutes in that soil to support a fairly big plant before they get low.

Try a good old water to run through with just plain ph'd water. Check your runoff as p.h as well.

Keep em on water for a few days and see how they do. Its most likely a lockout from over feeding.

Some soil mixes require no additional nutrients at all in large enough pots.

Just my stoned ramblings take it or leave it :)

do u guys recone i should tie the branchs down so light goes in the branchs more, i also pulled most of the real bad looking leaves of the 2 yellow plants will that help or will that make it worse , sorry for all the questions frist timer here lol i no for next time to let them veg for longer to get a bigger plant , as they are very small they look bigger in the photos

Thats of a hell of a big feed. I normally start at a quarter of the minimum recommended dose on the packet and work up. Soon as you see burnt tips you have gone too far.

Give them a good water to run 50% through and keep em on water for a while. If they start to look a bit sharper in the next 48 hours ish then you have a lockout/over fert issue and if they continue to decline its a deficiency.

Adding nutrients is really easy but taking them away is hard so start by taking them away before you risk making it worse.

Its just my ramble anyway, take it or leave it :)

boric acid 5ml per gallon superthrive 5ml per gallon. no more problems ya dig? 7.0PH h20 of coarse. monator ph, moisture, and ppm. keep the ppm below 700. Humidity should be between 45% and 70%. Temp should be between 78F and 86F.

Next watering take the runoff ppm and pH and make sure all the water you use to get the runoff is at pH7, may tell us somthing. Good luck

the ph in the soil of the good plants is around 7 an the ph in the yellow ones is lower around 5.8 , the soil still really wet in the yellow plants so should i wait b4 i water them an check the run off i also gave the yellow plants sum lime to rasie the ph about 4 or so days ago

IMO you have a lockup problem in the soil. You have an excess of nutrients which has dropped the ph of the soil and caused some of the nutrients to become unavailable.

I think you will find the EC of the runoff extremely high. Post up the reeding of the runoff asap and we can get cracking on a solution for you :)

Sounds about right, obviously looking back those particular plants couldn't cope with the fert levels you gave them as they are still left in your soil causing runoff pH to show low. Flush when next watering. Peace
