Got some broken cookies

Helllo to the forum. I'm a pretty new grower, although my two previous grows have not worked out so well. For this one I bought a half decent setup. Got an 80x80x160 tent. A mars hydro reflector P96, 4"" inlet and outlet. Temps between 22-28. I have 3 fastbuds grapefeuit and 1 Fast bud GSC in 11L pots. Bio bizz light mix with 3L perlite. The feed is bloom, fish mix, root juice, heaven and top max. They are 42days/ 6weeks today. Up until week 5 everything was perfect. Me being a right doughnut I forgot to give them any bloom until week 5, I thought all the plants were showing a phosphorous def. the 3 grapefruits are growing nicely but this GSC is still ill. I had her out last night to get some pics an I'm thinking a nitrogen deficiency. I feed these the same batch of feed, so I'm thinking the PH is good on all 4. I have s had a pen for previous grows and my feed is always within a decent range to be offset by the soil. But I broke my pen! I think I'm gonna flush. But could she just be lacking nitrogen? In week 6? Help is appreciated. I am feeding her 2ml of fish mix. Has this been enough? She is 45cm tall and the budd look ok still...

Flush today?

Got a legit ph pen from a friend. Is this general underfeeding? I used to grow in 5L pots. Should these plants need that much more?

All seem to be suffering. Here is run off of one I have fed as a tester. 3ml fish mix 3ml bloom 2ml top max 2ml heaven per litre and around 3litres given
Is this about right for week 6?

I am not familiar with your nutes, but it looks to me to be a lack of nitrogen. It appears your problems are primarily on the bottom which would be a mobile element. Your medium pH is very important, and if you are getting locked out, adding more nutes will make things worse fast. Some plants are way heavier or lighter eaters than others, I have never grown GSC but have a seed waiting, but just because other strains are doing fine on the same feeds, your GSC may just be a pig. You really need to get a reading on your medium pH before really knowing what to do with confidence.

Thank you for your response. I watered the GSC with plain water ph7 and my run off was 6.4. I'm no Ph expert but that seems ok. I am using the bio bizz range of nutrients. I will include my feed schedule

Bio bizz fish mix I use as my grow stimulant. Npk 5-1-4
Bio bizz root juice- root stimulant
Bio bizz heaven- bloom stimulant 0.91/0.18/0.24
Bio bizz top max- organic stimulator
Bio bizz bloom
Npk 2/7/4


Week 1 and 2 plain water and 2ml root juice

Week 3 0.5ml fish mix 2ml root juice

Week 4 1ml fish mix 2ml root juice 1ml top max

Week 5 2ml fish mix 2ml heaven 2ml bloom and a tsp of Epsom salts

Week 6 3ml fish mix 3ml bloom 2ml heaven 2ml top max

They seem to be fed once in s weekly cycle, 3L at a time. Nutrients every feed.

Now I know the ph is in range. Do I just increase the feed and keep an eye out?

Calculating the runoff, your medium pH is around 5.8. I think I would hit her up with stronger nutes and see if things stop going south.

lol this is so classic me .. ok so what happened was first you had too much N you got the down turned tips so maybe you backed off .. then she got bigger but you havent upped the N as she grew now she needs more N . Its good to look at other grows of those strains to see if they are heavy or light feeders. I have seen some go crazy with just light feeding abd some you cant feed enough lol Good luck

.... ... yeah, Biobizz is very mild stuff, many folks run it at full str. or close to it,...
