I give u pics, u give me deficiency name :)

here are 3 different strains, 2 mostly indica and 2 others mostly sativa.
sorry for some of the pictures quality.
here goes the first indica plant






the second indica






first sativa




second sativa





my guess is they mostly suffer from phosphorous defficiency mixed with a little nute burn. can any1 confirm this?

bump
any1 have any suggestions?

eas up on the nutes...

looks like overfeeding to me, maybe your pH is out of range, causing lock-out. give em a flush of plain water then feed at half strength.

Burnt tips is always a root problem, lack of oxygen maybe.

i was pretty sure burnt tips was nute burn. anyway im guessing they are all in the same container and same nutes, etc. they all have diff looking symptoms but it could all come down to 1 of 2 things in this situation. either ph is too high, or too much nutes like someone said. looks like too much n locking out p and k.

Fert burn, confirmed in part by N overdose symptoms on last plant.
And check your pH- keep it right around 5.8-6.0.
Make sure, too, that during your flood cycle, that peat puck is not getting soaked- flood to BELOW the level of your cloning plugs, because water sitting in them can actually lead to stem rot if your conditions are right for it.

I was running the GH 3 part lucas formula 8M-16B but last saturday starting week 3 of flower I changed it to bloom only so no nitrogen was in my mix and 2 days later the plants started showing signs of nitrogen defficiency so I added some Micro to add nitrogen but it didnt help at all so I decided to simply flush with str8 water and cal/mag last night. hopefully Im on the right track

 

[little-soldier]

how many days should I flush for?
3 days??

If those peat pucks are constantly soaked its not good - root rot.
