Bright Yellow Patches & leaves Turning Down, & Some plants turning up! - Any Advice?

You need an accurate way to measure ph.....even strips or drops from a pet store would be ok....but NO ph adjusters for fish.....just the testers.

Then water your plants and collect the water from the bottom......test ph.

Your issue has Got to either be ph or hydrohut I would think.......

right, I may not be able t get some Ph testing paper for a few days! I have CHE he'd with my battery powered reader (has 2 prongs that stick in the soil) this read ph7,

What else can I try to try and bring this baby back, don't want it getting ruisdd with only 6 weeks to go,

What I think is weird is that it is only on 1 of my 6 plants, so surly it can't be the tent?

Like stinky says,the tent can be one of the problems...There was a total recall of HydroHut because the plastic interior was made with a compound that was proven to f**k up grows...Hope your plants feel better man...

right don't thnk it is the tent, I have now noticed that the yellow tips of leaves has spread to the main bud on the stem on one of the other plants, we are in week 7 so just flushing with water now so if it is a nutes deficiency we can't add anything to correct it! Just hope they will last another 2 weeks, will the condition be damaging the bud?

You're missing the point.....if the ph in your pot is incorrect it doesn't matter what you do....your plants will not be able to absorb any nutes. Shoot, where's that old .....brb

A great read on ph.....

It doesn't really look like a hydrohut death to me either.....usually the entire plant turns lemon yellow and then just folds.....I think the issue is your ph.

Your question as to whethere they will last until finish is unknown. Poor conditions create unhealthy plants. Yours are obviously not healthy. Unhealthy plants tend to develop disease such as root rot etc....which can destroy your plant with 48-72 hours.

That's why growers like Stinky and myself don't slide along praying things will hold "just a bit longer" (because I've lost that game more than once) but try to make sure that plant doesn't GET into a situation where illness becomes much more likely.

Thanks for all the info so far guys,

Will be doing an accurate PH runoff reading later when i get home and will update the post, hopefully then we can correct it

Hello again, the plants are getting worse..

I have now done an accurate soil runoff ph test, came out at 6.6, tested my tap water and was 6.8

So what are my options to bring the plant back to health, as now into week 7 of flowering I cant add any nutes,

Bit worried about one of the other plants now, is getting the same bright yellow patches on the tips of the leaves around the buds, on the really sick one (in the pictures) the problem doesnt seem to have spread to the buds yet and remains on the larger top leaves, although the problem is getting worse

Any help would be apreciated

Thanks
