NFT Flowering week 5 - Some scary stuff happening...
Hi all, this will be my first post here, and I am currently in a bit of a panic! I hope someone may be able to take some time to assist me.
- Strain is BC Big Bud
- growing in NFT
- 40 L tank 5 plants
- 600w Sodium
- Ionic Bloom
- Ionic Silicon
- Ionic Liquid Oxygen
- Were from cuttings, vegged for 3 weeks on 24h using Ionic Grow
- Plants are 4ft tall currently in week 6 of flower(start)
Last Sunday went and cleaned tanks out, refilled and refed, adjusted PH down to 6. (I have 4 tanks)
Returned on Wednesday. 3 tanks are fine, 1 tank the leaves have started turning yellow, mainly at the bottom. Checked EC, was low, around 1, added more bloom.
By Friday, the situation is worse, more leaves yellow, further up the plant, and now branches are starting to droop as are leaves. Stamen starting to turn orange.
Saturday AM emptied tank. Left for a few hours with just PH adjusted water, added half strength nutes.
Yesterday, seems to have worsened, more drooping, more yellow leaves. Some appear to be twisting upside down. EC = 1.4 PH = 6.0 Water temp 22 degrees .
All other tanks are looking great, all have had the same feed at the same time and are all the same PH.
Can try and get photos uploaded later, but based on this information, any ideas?

Impossible to be sure without seeing pics, but yellowing of leaves from the bottom up is usually sign of a nitrogen deficiency. Which is perfectly normal coming to the end of flowering. How long have you plants got left?
Did you try lowering the ph to 5.7 and warm your res water up to over 50 degrees? I'm new so I am really not much help.
