Not sure what my plants are doing

[CanadianGrower]

This ones 6-5 weeks in to flowering, 1350 ppm, Ph 6.5 running 400 hps hydro.
theirs alot of single finger leaves, weird....


This one looks like fe defincy i think any ways same table as one above




this ones is 4 weeks in veg from clone, 1000 ppm 5.8 ph running 20/4 fluorescents





this pic is same table as first 2 pics



thx for lookin could use some advice

Lots ole problems I see, one the plants are starving lack of o2 due to algae growth in the rockwool,

1 tsp per gallon of water and water it on the rockwool will clear it up, alge is due to light or too much water keeping the rockwool moist.

This causes to clog the rockwool and not allow the roots to breath.

As for the rest of the problems I need you to fill this out so I can know your grow better so we can help fix your problem more presice. Also it looks like the plants are running too hot, the solution is too hot and the plants may have some salt built up.......

Those single leaves usually mean that the clone was taken while the mom was in flower and the clone was not fully revegged before flowering again (takes about a month).

 

[Pirate138]

Ive seen those single leaves to during a reveg. Maybe your timer was off?

 

[Guest]

Looks like too much nitrogen. That algae is going to have to be decrustified for sure.

 

[MynameStitch]

The single leaves like growtime has suggested is correct, but I what I was referring too was the cupping of the leaves.

[CanadianGrower]

oh no

oh no

To be honest the plants in that flowering have been cursed from the start to much to list going wrong.

The big shock is the co2 deficiency and the alge.
What do i put in my res to get rid of alge?
That describes the table its in its a very wet table. So the rock wool getting light forms alge??
heres more picks of that table

 

[upgradeshafted]

rockwool sucks...i would not usually give this antibiotic sulution but get some hydrogen peroxide and mix it 5mil per gallon with your nutrient mix and get rid of the green...wait for stitchs reply because she is way more thouro or how evere you spell that shit at this than i...peace

 

[MynameStitch]

1 tsp per gallon of water and water it on the rockwool will clear it up, alge is due to light or too much water keeping the rockwool moist.

This causes to clog the rockwool and not allow the roots to breath.

The roots that are in veg; you need to clean out the system and do a complete system flush and get some SM90 to rid the root rot before you do anything else; if the ones in veg have the algea use 1 tsp h202 per gallon of water.

You need to sterilize anything the water came in contact with and use hot water and h202 solution.

Once the system has been flushed clean, clean any drippers or anything else.
How long are you flooding those tables for? How ever long; it's too long if the roots are turning brown, it needs to be either less or not as long depending on which one.

Your nute solution is through the roof dude for those size of plants...... I would first clean the system like I posted above; then do a nute solution not so strong; the smaller plants that are around a foot tall I would use around 800 tops till they fully recover the 2 foot tall plants, would not go over 1000-1200 ppm

 

[CanadianGrower]

ya the rock wool is always moist and the always get light. So that solves that problem.
Im going to wash flood bed, and res tank and system with 5% bleach, and cut algea off top of the rock wool cubes.
Ill drop the ppm.
Ill try and get sm90 for the root, but Im very poor and my not be able to get it.
thx stitch
