Need help with defficiency diagnose

[psixerpsx]

Hello this Plant is in week 3 or 4 in flower and this defficiency started to show up i suspect calcium defficiency but i have been adding seaweed liquid or smaller doses of calmag regularly so i am not sure.
Lights are Jackson nemesis LED with Mars hydro ts1000 in 1x1m tent plants are growing in soil
Nutes plagron terra bloom in 3-4ml to L ,metrop aminoxtrem 0.9ml to L ,cannazym,sometimes seaweed liquid or calmag and Up to preflowering i used fulvic acid and silicate and since last watering i started with green sensation.
Ph entry from 5.8 to 6.5 and i use citric acid

Calcium deficiency. Are you applying silica foliar or watering it in? You're in the window for calcium deficiency. Typical in 4-5 weeks after flipping.

I was using GH Silicate mostly with watering but few times could be also with foliar but only in veg phase

Silica is best absorbed foliar. Poor absorption via roots. You have been giving it the entire grow I assume?

not with every watering and even when i used it it was smaller than normal dosage

Ditch it altogether. It must be used from seedling to flower. Every time. Just forget it for now.

okey and does it have something in common with that calcium deficiency ? i thought it could be something with too much PK blocking uptake of calcium or what... but it does not make much sense since i started using Green Sensation just last watering also with 0,7ml to L GH Calmag but i think it spreaded a little since then
also i have read that it is not good to use silica all way through flower because it cause buds to be rock hard and nice but not really good and i have experienced that

The leaves will begin to turn dark green on the bottom of the plant, bending at the tips creating a "claw". The stems and the foliage will become weak. The leaves that are not getting enough light are usually the first to show clawing symptoms. Nutrient burn signs may be apparent.

What’s your base water? RO can hold onto nutes especially calcium and can cause exactly this look. Especially if you water it in plain, it’ll even strip it out. Adding a little extra Ca will help if that’s the case and never just straight RO.

	PH	cal/mag [mmol/l]	calcium mg/l	magnesium mg/l	nitrogens ?
	7,50	3,6	96,2	29,2	5,8

this is some official water quality table from my area last one should be nitrogens in water or something like that it is really low against another places in my country and i am using it straight from tap no RO just waiting 24h or more before using

Looks very similar to my Lake Michigan tap water; plenty of Calcium and Magnesium.

i am in middle of europe so do you think i should use calmag even with base nutrients and bloom booster like Green Sensation ? which is also 9/10 PK

and what is the problem that cause this ?

I know nothing about your nutes, but as others have noted, looks like you need additional calcium.
Stop feeding non-essentials, just muddies the waters.
Less is more 99% of the time.

Since it’s not RO water and definitely looks like calcium is being locked out/not enough I’d consider if something I was adding could be causing it. I’m not an expert at all but just a tad too much bloom booster would be my #1 suspect. High PK locking out the Ca. Those leaves won’t heal and it’s okay just watch new growth to see. I’d let the plant use them up though until you see it’s getting back on track.

Hello again problem was solved on that plant defficiency is not progressing or much slower.
But another plant from same strain blue sunset sherbert that is little younger maybe now fourth week has started had developed similiar defficiency but i am not sure it is calcium .nutes light everything same as plant above.no other strains i have are having such problems
What is your opinion ? There are no bugs for sure i have been spraying with cannacure regularly and cleaned tent with alcohol but there are some white transparent patches on some leaves like from thrips
