Yellowing Leaves, Striping, leaf loss

[SarahJay]

Plant 1 is Fast n Vast by Heavy Weight seeds,

and was the first to start showing issues, she is the furthest ahead as far as flowering goes, but has almost dropped all her leaves . The buds are looking and smelling nice at least but hardly Vast

. Im going to keep feeding her for a week or two then flush at week 10 i think dependant on how the trichs are looking . All advice welcome .. ps cant get photos to load right way up. Apologies for cricked necks

Plant 2 is a Northern Lights x Blueberry.

This one hasnt dropped many leaves but has shown yellowing throughout and nute burn on the leaves. I have been going 1/2 strength with the nutes and this one still burnt. Im feeding all plants the same and i guess next time il pick one strain as its easier

Plant 3 another Heavy weight Fast n vast , this plant has grown very tall, one of two in air type pots, my least favourite of them all tbh , its had yellowing and leaf drop and it doesnt smell great. Being taller than the rest has been annoying.

This is the Critical Mass , this plant was very sensitive to nutes showing burn within hours of feeding and prob why i went easy on all the others , it burnt crazy quick and has just looked poorly since,

Last of the Fast n Vast , this plant is a week behind, so starts week 7 tomorrow , its in an air pot and and i experimented with LST on this one, its not looking bad its obviously getting the heavier nutes n cal mag and ph tested water ,im hoping ive saved this one from the crazy yellowing , fingers crossed.

I cant seem to find accurate 8 soil tester anywhere online could someone post a link?

I dont think im completely clear on adjusting water ph , the ph of the tap water here is 7, i use ph down to correct it to 6 or just above , even after nutes added it doesnt rise much like 6.1 , and run off today was 6.5 .. is this good or not? Everything ive read has said keep ph between 6-7 in soil growing so even though run off testing is dubious and inacurate surely its some sort of guide?

Are you sure they were nute burnt? They look hungry to me. Depending on nutes used typical dosage is water for first two weeks. 1/2 weeks 3&4. Depending on how they liked 1/2 you may be able to go full strength after a month. But all strains take to nutes different.

You said you transplanted also. Thats a big no for autoflowers last i checked unless very young. You may have broken roots and its eating leaves to rebuild root system for survival.

 

[STILLSMOKIN]

If you are getting 6.5 out after putting 6.1 your soil ph is probably around 7. Because soil is bringing ph up. Also you cant take a test from first runoff either. Saturate soil to start of run off. Wait 30mins and water again. Read ph from this runoff.

Im coming to the end with these lovely plants, ive learnt so much, and im confident theres gonna be a lovely stash of bud at the end.
